Batak is a collective term used to identify a number of ethnic groups predominantly found in North 
Sumatra, 
Indonesia. The term is used to include the 
Toba, 
Karo, 
Pakpak, 
Simalungun, 
Angkola and 
Mandailing, which are distinct but related groups with distinct, albeit related, languages and customs (
adat). Occasionally it is also used to include the 
Alas people of Central/Southern 
Aceh, but usually only as relates to language groups.
 
In North Sumatra, Toba people typically assert their identity as 
'Batak', while other 'Bataks' may explicitly reject that label, 
preferring instead to identify as specifically 'Simalungun', 'Karo', etc.
Prehistory
Linguistic and archeological evidence indicates that Austronesian speakers first reached Sumatra from Taiwan and the Philippines through Borneo and/or Java about 2,500 years ago, and the Batak probably evolved from these settlers. While the archaeology of southern Sumatra testifies the existence of 
neolithic settlers, it seems that the northern part of Sumatra was 
settled by agriculturalists at a considerably later stage.

Although the Batak are often considered to be isolated peoples, 
largely because they were inland, away from influence by seafaring 
European colonials, there is evidence that they have been involved with 
trade and contact with other neighbouring kingdoms for a millennium or 
more. Reliable historical records of the Batak before 1800 are almost 
non-existent. The Bata were possibly documented in Zhao Rugua's 13th-century Description of the Barbarous People, which refers to a 'Ba-ta' dependency of Srivijaya. The Suma Oriental, of the 15th century, refers to the kingdom of Bata, bounded by Pasai and the Aru Islands.
The Bataks were likely involved with trade with Srivijaya for benzoin and camphor,
 both of which were important commodities for trade with China, and grew
 in the Batak lands of northwest Sumatra, perhaps from the eighth or 
ninth centuries, and continuing for the next thousand years, Batak men carrying the products on their backs for sale at ports.
It is suggested that the important port of Barus in Tapanuli was populated primarily by Batak people. A Tamil
 inscription has been found in Barus dated 1088, while contact with 
Chinese and Tamil traders took place at Kota Cina, a trading town 
located in what is now northern Medan
 that was established in the eleventh century, and comprising 10,000 
people by the twelfth century. Tamil remains have been found on key 
trade routes to the Batak lands.
These trading opportunities may have caused migration of Batak from 
Pakpak and Toba to the present-day Karo and Simalungun 'frontier' lands,
 where they were exposed to greater influence from visiting Tamil 
traders, while the migration of Batak to the Angkola-Mandailing lands 
may have been prompted by eighth-century Srivijayan demand for camphor.
The Karo marga or tribe Sembiring
 "black one" is believed to originate from their ties with Tamil 
traders, with specific Sembiring sub-marga, namely Brahmana, Colia, 
Pandia, Depari, Meliala, Muham, Pelawi, and Tekan all of Indian origin. 
Tamil influence on Karo religious practices are also noted, with the 
pekualuh secondary cremation ritual specific to the Karo and Dairi 
people.
From the sixteenth century onwards, Aceh increased the production of pepper,
 an important export commodity, and in doing so needed to import rice, 
which grew well on the Batak wetlands. Batak people in different areas 
cultivated either sawah "wet rice fields" or ladang "dry 
rice", and the Toba Batak, most expert in agriculture, would have 
migrated to meet demand in new areas. The increasing importance of rice 
had religious significance, increasing the power of the Batak high 
priests, who had responsibility for ensuring agricultural success.
 Language
Batak speak a variety of closely related languages, all members of the Austronesian language family. There are two major branches, a northern branch comprising the Pakpak-Dairi, Alas-Kluet and Karo
 languages, which are similar to each, and a distinctly different 
southern branch, comprising three mutually intelligible dialects: Toba, Angkola and Mandailing. Simalungun
 is an early offspring of the southern branch. Some Simalungun dialects 
can be understood by speakers of Batak Karo, whereas other dialects of 
Simalungun can be understood by speakers of Toba. This is due to the 
existence of a linguistic continuum that often blurs the lines between 
the Batak dialects. Batak dialect still influences the dialects in Medan city until now.
The Batak possess their own script known as the Surat Batak.
 The writing has chiefly ceremonial importance within traditional 
religious ceremonies, and was subject to little change for this reason. 
It is likely that the Batak people originally received their writing 
system from southern Sumatra.
Society
Batak societies are 
patriarchally organized along clans known as 
Marga. A traditional belief among the Toba Batak is that they originate from one ancestor "Si Raja Batak", with all 
Margas descended from him. A family tree that defines the father-son relationship among Batak people is called 
tarombo.
 In contemporary Indonesia, Batak people have a strong focus on 
education and a prominent position in the professions, particularly as 
teachers, engineers, doctors and lawyers. Toba Batak are known 
traditionally for their weaving, wood carving and especially ornate stone tombs.
 
Before they became subjects of the colonial 
Dutch East Indies
 government, the Batak had a reputation for being fierce warriors. Today
 the Batak are mostly Christian with a Muslim minority. Presently the 
largest Christian congregation in Indonesia is the 
HKBP (
Huria Kristen Batak Protestan) Christian church. The dominant Christian theology was brought by 
Lutheran German missionaries in the 19th century, including the well-known missionary 
Ludwig Ingwer Nommensen. Christianity was introduced to the Karo by 
Dutch Calvinist missionaries and their largest church is the GBKP (
Gereja Batak Karo Protestan). The 
Mandailing
 and Angkola Batak were converted to Islam in the early 19th century. A 
significant minority of Batak people do not adhere to either 
Christianity or Islam, however, and follow traditional practices known 
as the 
agama si dekah, the old religion, which is also called 
perbegu or 
pemena.
 
 Ritual cannibalism
Ritual cannibalism is well documented among Batak people, performed in order to strengthen the eater's 
tendi.
 In particular, the blood, heart, palms and soles of the feet were seen as rich in 
tendi.
 
In 
Marco Polo’s
 memoirs of his stay on the east coast of Sumatra (then called Java 
Minor) from April to September 1292, he mentions an encounter with hill 
folk whom he refers to as “man-eaters”.
 From secondary sources, Marco Polo recorded stories of ritual 
cannibalism among the "Battas". Marco Polo's stay was restricted to the 
coastal areas, and he never ventured inland to directly verify such 
claims. Despite never personally witnessing these events, he was 
nonetheless willing to pass on descriptions which were provided to him, 
in which a condemned man was eaten:
 
- "They suffocate him. And when he is dead they have him cooked, and 
gather together all the dead man's kin, and eat him. And I assure you 
they do suck the very bones till not a particle of marrow remains in 
them...And so they eat him up stump and rump. And when they have thus 
eaten him they collect his bones and put them in fine chests, and carry 
them away, and place them in caverns among the mountains where no beast 
nor other creature can get at them. And you must know also that if they 
take prisoner a man of another country, and he cannot pay a ransom in 
coin, they kill him and eat him straightway.
 
The Venetian 
Niccolò de' Conti (1395–1469) spent most of 1421 in Sumatra in the course of a long trading journey to 
Southeast Asia
 (1414–1439), and wrote a brief description of the inhabitants: "In a 
part of the island called Batech live cannibals who wage continual war 
on their neighbors.".
 
Sir Thomas 
Stamford Raffles
 in the 1820s studied the Batak and their rituals and laws regarding the
 consumption of human flesh, writing in detail about the transgressions 
that warranted such an act as well as their methods. Raffles stated that "It is usual for the people to eat their parents 
when too old to work," and that for certain crimes a criminal would be 
eaten alive: “The flesh is eaten raw or grilled, with lime, salt and a 
little rice.”.
 
The German physician and geographer 
Franz Wilhelm Junghuhn visited the Batak lands in 1840-41. Junghuhn says about cannibalism among the Batak (whom he called "Battaer"):
 
- “People do the honest Battaer an injustice when it is said that they
 sell human flesh in the markets, and that they slaughter their old 
people as soon as they are unfit for work...They eat human flesh only in
 wartime, when they are enraged, and in a few legal instances.”
 
Junghuhn tells how after a perilous and hungry flight he arrived in a
 friendly village, and the food that was offered by his hosts was the 
flesh of two prisoners who had been slaughtered the day before,
 however he maintains that the Batak exaggerated their love of human 
flesh in order to frighten off would-be invaders and to gain occasional 
employment as mercenaries for the coastal tribes who were plagued by pirates .
 
Oscar von Kessel visited Silindung in the 1840s and in 1844 was 
probably the first European to observe a Batak cannibalistic ritual in 
which a convicted adulterer was eaten alive. Interestingly, his 
description parallels that of Marsden in some important respects, 
however von Kessel states that cannibalism was regarded by the Batak as a
 judicial act and its application was restricted to very narrowly 
defined infringements of the law including theft, adultery,
 spying or treason. Salt, red pepper and lemons had to be provided by 
the relatives of the victim as a sign that they accepted the verdict of the community and were not thinking of revenge.
 
Ida Laura Pfeiffer visited the Batak in August 1852 and although she did not observe any cannibalism, she was told that:
 
- "Prisoners of war
 are tied to a tree and beheaded at once; but the blood is carefully 
preserved for drinking, and sometimes made into a kind of pudding with 
boiled rice. The body is then distributed; the ears, the nose, and the 
soles of the feet are the exclusive property of the Rajah,
 who has besides a claim on other portions. The palms of the hands, the 
soles of the feet, the flesh of the head, and the heart and liver, are 
reckoned peculiar delicacies, and the flesh in general is roasted and 
eaten with salt. The Regents
 assured me, with a certain air of relish, that it was very good food, 
and that they had not the least objection to eat it. The women are not 
allowed to take part in these grand public dinners."
 
Dutch and German 
missionaries to the Batak in the late 19th century observed a few instances of cannibalism and wrote lurid descriptions to their home parishes in order to raise donations. The growing Dutch influence in northern Sumatra led to increased Malay influence in coastal trade and plantations, pushing the Karo farther inland. Growing ethnics tensions culminated in the 1872 Karo Rebellion
 where the Karo were suppressed by Dutch and Malay forces. Despite this,
 Karo resistance to Dutch imperialism lingered into the early twentieth 
century.
 In 1890 the Dutch colonial government banned cannibalism in the regions under their control.
 Rumors of Batak cannibalism survived into the early 20th century but it
 seems probable that the custom was rare after 1816, due partially to 
the influence of 
Islam.
 
Geography
  | 
| Batak's in North Sumatra | 
The Batak lands consist of 
North Sumatra province, excluding 
Nias island and the historically Malay kingdoms of the East coast. In addition, part of the Karo lands extend into modern-day 
East Aceh Regency in 
Aceh province, while parts of the Mandailing lands lie in 
Rokan Hulu Regency in 
Riau. Significant numbers of Batak have migrated in recent years to prosperous neighbouring Riau province.
 
To the south of North Sumatra are the Muslim 
Minangkabau of 
West Sumatra, while to the north there are various Muslim Acehnese peoples.
 
 Traditional Batak religion
Batak village on Samosir island
 
 
 
The various Batak cultures differ in their pre-colonial religious 
ideas as they do in many other aspects of culture. Information about the
 old religious ideas of the 
Mandailing
 and Angkola in southern Batakland is incomplete, and very little is 
known about the religion of the Pakpak and Simalungun Batak. For the 
Toba and Karo on the other hand the evidence in the writings of 
missionaries and colonial administrators is relatively abundant. 
Information on the traditional forms of Batak religion is derived mainly
 from the writings of German and Dutch missionaries who became increasingly concerned with Batak beliefs towards the end of the 19th century.
 
Various influences affected the Batak through their contact with Tamil and Javanese traders and settlers in southern Batakland, and the east and west coast near Barus and Tapanuli, in particular the large Padang Lawas
 temple complex in Tapanuli. These contacts took place many centuries 
ago and it is impossible to reconstruct just how far the religious ideas
 of these foreigners were adopted and reworked by the Batak. It is 
suggested that the Bataks adopted aspects of these religions, 
specifically Mahayana Buddhist, 
Shaivist, and 
Tantrist practices
 within their own customs.
 
The modern Indonesian state is founded on the principles of pancasila,
 which requires the belief in 'one and only God', the practice of either
 Protestantism, Catholicism, Islam, Buddhism or Hinduism, one of which 
must be entered on an individual's KTP.
 Traditional religions are not officially recognised, and accordingly 
traditional religions are increasingly marginalised, although aspects of
 the traditional Batak religion are still practised alongside 
Christianity, and, to a lesser extent, Islam.
 Creation myths
There are many different versions in circulation. These were formerly
 passed down through oral tradition but have now been written down in 
the local languages. There are also large collections of Batak tales 
collected by European scholars since the mid-19th century and recorded 
in European languages, mostly Dutch.
At the beginning of time there was only the sky with a great sea 
beneath it. In the sky lived the gods and the sea was the home of a 
mighty underworld dragon Naga Padoha. The earth did not yet exist and human beings, too, were as yet unknown. All the surviving myths record that at the beginning of creation stands the god Mula Jadi Na Bolon.
 His origin remains uncertain. A rough translation of the name is the 
"beginning of becoming". The creation of everything that exists can be 
traced back to him. Mula Jadi lives in the upper world which is usually thought of as divided into seven levels. His three sons, Batara Guru, Mangalabulan and Soripada were born from eggs laid by a hen fertilized by Mula Jadi. Two swallows act as messengers and helpers to Mula Jadi in his act of creation. Their functions vary in the different versions. Mula Jadi
 begets three daughters whom he gives as wives for his three sons. 
Mankind is the result of the union of the three couples. Besides the 
three sons of Mula Jadi there is another god, Asiasi, whose place and function in the world of the gods remains largely unclear. There is some evidence that Asiasi can be seen as the balance and unity of the trinity of gods.
The ruler of the underworld, i. e. the primeval sea, is the serpent-dragon Naga Padoha. He too existed before the beginning and seems to be the opponent of Mula Jadi. As ruler of the underworld Naga Padoha also has an important function in the creation of the earth.

What all the six gods so far mentioned have in common is that they 
play a minor role in ritual. They do not receive any sacrificial 
offerings from the faithful and no places of sacrifice are built for them. They are merely called on in prayers for help and assistance.
The origin of the earth and of mankind is connected mainly with the daughter of Batara Guru, Sideak Parujar, who is the actual creator of the earth. She flees from her intended husband, the lizard-shaped son of Mangalabulan,
 and lets herself down on a spun thread from the sky to the middle world
 which at that time was still just a watery waste. She refuses to go 
back but feels very unhappy. Out of compassion Mula Jadi sends his granddaughter a handful of earth so that she can find somewhere to live. Sideak Parudjar
 was ordered to spread out this earth and thus the earth became broad 
and long. But the goddess was not able to enjoy her rest for long. The 
earth had been spread out on the head of Naga Padoha, the dragon 
of the underworld who lived in the water. He groaned under the weight 
and attempted to get rid of it by rolling around. The earth was softened
 by water and threatened to be utterly destroyed. With the help of Mula Jadi and by her own cunning Sideak Parudjar was able to overcome the dragon. She thrust a sword into the body of Naga Padoha up to the hilt and laid him in an iron block. Whenever Naga Padoha twists in the fetters an earthquake occurs.
After the lizard-shaped son of 
Mangalabulan, the husband the gods intended for her, had taken another name and another form, 
Sideak Parujar marries him. 
Sideak Parujar
 becomes the mother of twins of different sexes. When the two have grown
 up their divine parents return to the upper world leaving the couple 
behind on the earth. Mankind is the result of their incestuous union. The couple settle on Pusuk Buhit, a volcano on the western shore of 
Lake Toba, and found the village of Si Anjur Mulamula. The mythological ancestor of the Batak, 
Si Raja Batak is one of their grandchildren.
 
The tendi cult
 
In the religious world of the Toba and Karo Batak the gods and the 
creation of mankind are far less significant than the complex concepts 
connected with the tendi (Karo) or tondi (Toba) and the begu. Probably the most useful translations of these terms are "life-soul" and "death-soul". A person receives his "life-soul" (tendi) from Mula Jadi Na Bolon before he is born. The destiny of the individual tendi is decided by the tendi itself before birth. Various myths are woven around manner in which the tendi choose their destiny from Mula Jadi. Warneck, a missionary and for a long time superintendent (ephorus) of the Batak Church, recorded two particularly expressive myths in his major work on Batak religion. What is significant is that the tendi themselves are responsible for their destiny:
- "Mula Jadi presents him with all kinds of things to choose from. If the tendi
 asks for ripe pepper, then the person whom he animates will be a poor 
fellow; if he asks for flowers, then he will live only a short time; if 
he asks for a hen, the person will be restless; rags indicate poverty; 
an old mat, lack of fame; a gold piece, wealth; plate, spear, medicine 
pot indicate that he will become a great chief or understand magic 
arts."
 
- "With Mula Jadi in the upper world is a mighty tree called Djambubarus. Mula Jadi
 has written on all its leaves. On one leaf is written 'many children', 
on others 'wealth' or 'respect' and so on. 'Contemptible life', 
'poverty', 'wretchedness' are also written on the leaves. All the 
possible different fates of the person are entered on the leaves. Every tendi that wishes to descend to the middle world must first ask Mula Jadi for one of the leaves. Whatever is written on the leaf chosen by him will be his destiny in the middle world."
 
Among the Karo and the Toba there are sometimes widely diverging versions of where the tendi dwells and how many tendi there are. According to the Toba a person has seven tendi. The second tendi is found in the placenta and amniotic fluid
 of the new-born baby, and accordingly the afterbirth is given special 
attention after the birth of a child. It is usually buried under the 
house, is called saudara (brother) and is regarded as the 
person's guardian spirit. Similar ideas about the afterbirth are also 
found among the Karo, who also bury the placenta and amniotic fluid 
under the house and regard them as two guardian spirits (kaka and agi) who always remain close to the person.
  | 
| Batak : Totem Pole | 
All Batak regard the loss of 
tendi as signifying a great danger for "body and soul". 
Tendi can be separated from their owners through inattentiveness, or as a result of black magic by a 
datu with evil intentions. In other words, the 
tendi is not tied to the body; it can also live for a time outside the body. The final loss of the 
tendi inevitably results in death. There are a variety of ideas about where exactly in the body the 
tendi
 dwells. It is present to a particularly high degree in certain parts of
 the body, especially the blood, the liver, the head and the heart. 
Sweat too is described as rich in 
tendi. It is believed that illnesses are connected with the absence of 
tendi, and the bringing back of the 
tendi is a main method of healing. The Karo, for instance, have gifts, called 
upah tendi (
upah = wage, payment, gift), which they give to their 
tendi so that their 
tendi
 stay with them. These gifts may consist of a knife, a gong, a 
particular piece of clothing, a water buffalo or a small holy place. The
 gifts are carefully cared for in order to keep the 
tendi satisfied.
 
Tendi love the sound of the surdam (a bamboo flute). If a tendi has abandoned the body of a patient, the playing of the surdam in the raleng tendi ritual can contribute to the tendi returning to the body of the sick person. It must be emphasized that only the datuk are in a position to interpret and influence people's tendi correctly. If their endeavors are unsuccessful, then clearly the tendi has chosen another destiny for itself.
 Death cult
At death the 
tendi leaves the human body through the fontanelle and the "death-soul" (
begu) is set free. It is thought that the 
tendi vanishes and after the death of any human being only the 
begu continues to exist. The Batak believe that the 
begu
 continue to live near their previous dwelling (in a village of the dead
 which is thought to be situated not far from the cemetery) and that 
they may contact their descendants. Bad dreams, particular misfortune 
and such like may be signs that the 
begu of an ancestor is not satisfied with the behavior of its descendants. Any individual can attempt to pacify an enraged 
begu by means of food and drink offerings and prayers. If this does not work, a 
datu or a 
guru must be called in. The 
begu are not immortal, since death also rules in the land of the dead: a 
begu dies seven times before it is changed into a straw and finally becomes earth.
 
The Batak believe that three categories of begu exist. The bicara guru are the begu of stillborn babies or of babies who have died before teething. It is possible to turn bicara guru into guardian spirits if misfortune has befallen the family of the child shortly after its death. With the help of a guru sibaso, the bicara guru
 can be made the family's guardian spirit for which a shrine is provided
 and to which sacrifices are regularly made. Once a year the bicara guru is accorded a special feast, preceded by ritual hair washing.
The begu of members of the family who have had a sudden death (mate sada-uari)
 can also act as guardian spirits for the family. They include the 
victims of accidents, suicides, murder victims, or people struck by 
lightning. A shrine is built where they are venerated and where 
sacrifices are made. A third category consists of the begu of dead virgins (tungkup). Their graves, called bata-bata or ingan tungkup, are maintained for a long time by their relatives.
 Burial traditions
Batak 
burial traditions are very rich and complex. Immediately after death various ritual actions are performed to make the 
begu
 understand that from now on its world is separate from that of its kin.
 Symbolically this is done by reversing the mat on which the corpse is 
laid out so that the body lies with its head at the foot of the mat. 
Thumbs and toes respectively are tied together and the body is rubbed 
all over with 
camphor and its orifices stopped with camphor, then it is wrapped in a white cotton cloth. During this 
perumah begu ceremony a 
guru sibaso declares to the 
begu of the deceased that it is definitely dead and must take leave of its relatives.
 
Wealthier families have their coffins (Karo: 
pelangkah) made of the wood of the 
kemiri tree (
Ateurites rnoluccana), carved in the shape of a boat, its bow decorated with the carved head of a 
hornbill, or a horse, or a 
mythical beast known as a 
singa. The lid is then sealed with 
resin
 and the coffin may be placed in a special location near the family's 
house until a reburial ceremony can take place (see below). Families 
that are not wealthy use simple wooden coffins or wrap the body in a 
straw mat.
 
The corpse is carried a few times round the house, usually by women, and then to the 
cemetery with musical accompaniment from the 
gondang
 orchestra and the continual firing of guns. At any crossroads the 
corpse is put down and eleven people go around it four times to confuse 
the 
begu. It is hoped that the 
begu will then be unable to
 find its way back to the village. When the funeral procession arrives 
at the cemetery the grave is dug and the corpse laid in it, flat on its 
back. Care is taken that the head lies towards the village so that, in 
the unexpected event that the body should get up, he or she will not be 
looking in the direction of the village. The bodies of 
datuk and 
those who have died from lightning are buried sitting up with their 
hands tied together. The palms of the hand are tied together and 
betel placed between them.
 
Reburial
The burial tradition includes a reburial ceremony in which the bones 
of one's ancestors are reinterred several years after death. This 
secondary burial is known among the Toba Batak as mangongkal holi, among the Karo as nurun-nurun.
 In a ceremony lasting several days the bones of a particularly honored 
ancestor and those of his descendants are exhumed, cleaned, mourned and 
finally laid to rest again in a bone house known as a tugu or tambak:
- "On the morning of the first day of the festival the graves in the 
cemetery are opened and the bones of the ancestors that are still there 
are removed. The unearthing of the skulls is presented as especially 
moving. The bones are collected in baskets lined with white cloth and 
then ritually cleaned by the women using the juice of various citrus
 fruits. The exhumation and cleaning of the bones is accompanied by the 
singing of laments. The bones are kept in the baskets in the tugu until the next morning, when the remains are wrapped in traditional cloths (ulos)
 and transferred from the baskets to small wooden coffins. After long 
speeches and a communal prayer the coffins are nailed down and placed in
 the chambers of the tugu. A feast consisting of meat and rice follows and traditional dances are performed."
 
In ancient times these 
sarcophagi
 were carved from stone or constructed from wood and later brick. 
Nowadays they are made of cement or concrete. Large and very ornate 
tugu can be seen around Lake Toba and on the island of 
Samosir.

| Batak tugu on the island of Samosir, Lake | 
One motive for the reburial ceremony appears to be to raise the status of the begu
 of the deceased. Traditional Batak beliefs hold that the dead occupy a 
hierarchical status similar to the social position they held in life. 
This means that a rich and powerful individual remains influential after
 death, and this status can be elevated if the family holds a reburial 
ceremony. A rich descendant can advance a begu to the status of a sumangot by means of a great ceremony and a horja
 feast which can last up to seven days. In antiquity a vast number of 
pigs, cattle or even buffalo were slaughtered at such festivals, and the
 gondang orchestra provided an accompaniment.
The next level up from the 
sumangot is the 
sombaon, who are the spirits of important ancestors who lived ten to twelve generations ago. To raise a 
sumangot to a 
sombaon requires another great festival, a 
santi rea,
 often lasting several months, during which the inhabitants of the whole
 district come together. These powerful ancestor spirits offer 
protection and good fortune to their descendants, but the ceremony also 
serves to establish new 
kinship groups descended from the ancestor thus honored.
 
Traditional Batak medicine
In traditional Batak society 
datuk (animist priests) as well as 
gurus practiced 
traditional medicine,
 although the former were exclusively male. Both professions were 
attributed with supernatural powers and the ability to predict the 
future. Treatments and healing rituals bear some resemblance to those 
practiced by 
dukuns
 in other parts of Indonesia. Following the Christianization of the Toba
 and Karo Batak in the late 19th century, missionaries discouraged 
traditional healing and divination and they became largely 
clandestine activities.
 
Both 
datuk and 
guru healers also practiced 
divination by consulting a 
pustaha,
 a handwritten book made of wood and bark in which were inscribed 
recipes for healing remedies, incantations and songs, predictive 
calendars, and other notes on magic, healing and divination written in 
poda, an archaic 
Batak shorthand. According to Winkler, there were three categories of 
Pustaha based on the purpose of their usage:
 
- 1. Protective Magic, which includes diagnosis, therapy, medicinal mixes which have magical properties, such as amulets, parmanisan (love charms), etc.
 - 2. Destructive Magic, which encompasses the art of making poison, the art of controlling or utilizing the power of certain spirits, calling the pangulubalang, and the art of making dorma (magical formulas for causing a person to fall in love).
 - 3. Divination, which involves oracles (words of the gods), the wishes of the spirits, commands from the gods and from the spirits of the ancestors, and an almanac or calendrical system (porhalaan), and astrology to determine auspicious days and months to accomplish certain actions or goals.
 
The 
datu or 
guru consulted the 
pustaha when 
presented with a difficult problem, and in time this became in itself a 
ritual. When missionaries began to discourage traditional healing and 
augury the 
Bible may have been adopted by some 
gurus in place of the 
pustaha.
 
Among the most important healing ceremonies performed in Toba and Karo communities is that of recalling the 
jinujung, or personal guardian spirit. According to Toba and Karo 
cosmology, each person receives a 
jinujung in childhood or at 
puberty
 and they keep it for life unless they are unfortunate enough to lose 
it, in which case they will fall ill. In order to call the 
jinujung back, a female 
guru (
guru sibaso in Karo) goes into a 
trance and the 
jinujung
 will enter into her and speak through her mouth. At this time the sick 
person or the family can negotiate ritual payment to entice it to 
return.
 
Traditional healers are not powerful enough to cure illness due to the loss of a person's 
tendi (this falls under the jurisdiction of the 
datuk), however they do play a role in communicating with 
begu and influencing their behavior.
 
 Malim
Malim is the modern form of the Batak Toba religion. Practitioners of Malim are called Parmalim.
 
Non-Malim Batak peoples (those following Christian or Muslim faith) 
often continue to believe certain aspects of traditional Batak spiritual
 belief.
The 'Perodak-odak' movement among the Karo people in the 1960s was a 
reassertion of the traditional Karo religion, but has largely faded; a 
subsequent Karo movement to identify as 
Hindu was noted starting from the late 1970s in order to adopt, if only in name, one of the recognised religions of Indonesia, while in practice still following traditional beliefs.
 
 Abrahamic religions
 Christianity
At the time of Marco Polo's visit in 1292 the people were described as "wild idolaters" who had not been influenced by outside religions, however by Ibn Battuta's visit in 1345 Arab
 traders had established river-ports along the northern coasts of 
Sumatra and Sultan Al-Malik Al-Dhahir had recently converted to Islam.
Sir Stamford Raffles perceived the Batak lands as a buffer between 
the Islamic Aceh and Minang kingdoms, and encouraged Christian 
missionary work to preserve this.
 This policy was continued by the Dutch, who deemed the non-Muslim lands the 'Bataklanden'.
 
In 1824 two British Baptist missionaries, Richard Burton and Nathaniel Ward, set off on foot from Sibolga and traveled through the Batak lands. After three days' journey they reached the high valley of Silindung and
 spent about two weeks in the Batak region. Considering the shortness of
 their stay their account reveals very intensive first-hand observation.
 This was followed in 1834 by 
Henry Lyman (missionary) and 
Samuel Munson from the 
American Board of Commissioners for Foreign Missions who met with a more hostile reception.
 According to 
Ida Pfeiffer:
 
- "Some time before the arrival of the missionaries some Mohammedan 
priests had made their appearance in the country, accompanied by a band 
of armed men, and had forced them by fire and sword to accept their 
religion...When, therefore, the unfortunate Americans presented 
themselves as religious teachers, the Battakers imagined they were going
 to have a repetition of the same scenes, and resolving to be beforehand
 with their tormentors, they killed them and ate them up."
 
Herman Neubronner van der Tuuk
 was employed by the Nederlands Bijbel Genootschap (Netherlands Bible 
Society) in the 1850s to produce a Batak–Dutch grammar-book and a 
dictionary, which enabled future Dutch and German missionaries to 
undertake the conversion of the Toba and Simalungan Batak.
 
The first German missionaries to the Lake Toba region arrived in 1861, and a mission was established in 1881 by Dr. 
Ludwig Ingwer Nommensen of the German 
Rhenish Missionary Society. The 
New Testament was first translated into Toba Batak by Dr. Nommensen in 1869 and a translation of the 
Old Testament was completed by P. H. Johannsen in 1891. The complete text was printed in Latin script in Medan
 in 1893, although H. O. Voorma describes the translation as “not easy 
to read, it is rigid and not fluent, and sounds strange to the 
Batak…[with] a number of errors in the translation.” 
 
The Toba and Karo Bataks accepted 
Christianity rapidly and by the early 20th century it had become part of their cultural identity.
 
This period was characterized by the arrival of Dutch colonists and 
while most Bataks did not oppose the Dutch, the Toba Batak fought a 
guerrilla war that lasted into the early 20th century and ended only with the death in 1907 of their charismatic priest-warrior-king Si 
Singamangaraja XII, who had battled the Dutch during the First Toba War with both magic and weaponry.
 
 Batak churches
The Huria Kristen Batak Protestan (
HKBP) Church was established in 
Balige in September, 1917. By the late 1920s a nursing school was training 
nurse midwives there. In 1941, the Gereja Batak Karo Protestan (GBKP) was established.
 Although missionaries ceded much power to Batak converts in the first 
decades of the 20th century, Bataks never pressured the missionaries to 
leave and only took control of church activities as a result of 
thousands of foreign missionaries being interned or forced to leave
 after the 1942 invasion of Sumatra by the 
Japanese.
 
The 
Gereja Kristen Protestan Simalungun,
 originally part of the HKBP and preaching in Batak Toba language, 
eventually became a distinctively Simalungun church, adopting Simalungun
 customs and language, before finally incorporating as GKPS in 1963.
 
 Islam
The Mandailing and Angkola people, occupying the southern Batak lands, came under the influence of the neighbouring Islamic 
Minangkabau people as a result of the 
Padri War (1821–1837).
 Some Mandailing had previously converted to Islam, but the Padri war was a watershed event, with the Padri 
Wahabbis suppressing traditional 
adat and promoting 'pure' Islamic faith. Over time Mandailing Islam, has been brought closer to the predominant Southeastern 
Shafi`i school of Islam as a result of Mandailing discourse with other Islamic practitioners and the practice of 
hajj,
 although traditional elements remain, such as dividing inheritance 
among all children, a Mandailing rather than Islamic practice. Islam 
caused the decline in importance of marga, with many Mandailing 
abandoning their marga in favour of Muslim names, much less so among the
 Angkola to their North.
 
The advent of Islam also caused the relegation of the datuk to a 
medicine man, with traditional rice-planting ceremonies and other such 
remnants of traditional culture deemed incompatbile with Islam. The 
'pasusur begu', a ceremony invoking ancestors to aid the community, was 
also suppressed. Other aspects of adat were however tolerated, with the 
Mandailing Islamic ideology placing adat on the same level as Islamic 
law, as in contrast with the Minang practice of placing Islamic law 
above adat. In more recent times, learned Islamic scholars (ulama) 
studying abroad, have suggested that many traditional Mandailing 
practices, such as the 'Raja' hereditary leaders, were in conflict with 
Islam, being indicative of 'pele begu'. The Islamist ulama were in 
conflict for authority with the Namora-Natora, the traditional village 
legal practitioners, who were influenced by adat as much as Islam.
Christian missionaries had been active among the northern Mandailing 
from 1834 onwards, but their progress was restricted by the Dutch 
government, who feared conflict between newly converted Christians and 
Muslims. In addition, the lingua franca of the government was Malay, 
associated with Muslims, as were government civil servants, creating the
 perception that Islam was the religion of modernity and progress. 
Missionaries determined that resistance among the Muslim Mandailing to 
Christianity was strong, and the missionaries abandoned them as 
'unreachable people', moving north to evangelize the Toba.
At the turn of the 20th century, nearly all Mandailing and Angkola 
were Muslims. Despite this, the Dutch administration them as part of the
 Bataklanden, and therefore heathen or Christian. This perception was an
 inaccurate one, and many Mandailing strongly rejected the 'Batak' 
label.
Abdullah Lubis, writing in the 1920s, claimed that while the Mandailing
 followed Batak marga practice, they had never followed the Batak 
religion, and that the Mandailing people pre-dated the Toba, having 
acquired marga directly from 'Hindu' visitors. In the Dutch census, the 
Mandailing objected strongly to being listed in the census as 'Batak 
Mandailing'. Mandailing in Malaysia (who migrated in the years following
 the Padri war), had no such objection to their being deemed 'Malays', 
and indeed Malaysian Mandailing retain little of their distinct 
identity, partly due to a British colonial policy of rice-land ownership
 restrictions for all but Malay-speaking Muslims, and the disapproval of
 'Batak' Muslim practices by the existing Malay Muslim population.
 Other influences
Modern Batak people are subject to religious influences through 
marriage and migration. Formerly Christian villages may, through 
migration of Muslim outsiders, lose their explicitly Christian identity,
 with pork excluded from wedding feasts in favour of meats acceptable to
 Islam.
