During the time when the Batak kingdom was based in Bakara, the Sisingamangaraja dynasty of the Batak kingdom divided their kingdom into four regions by the name of Raja Maropat, which are:-
Raja Maropat Silindung
Raja Maropat Samosir
Raja Maropat Humbang
Raja Maropat Toba
Dutch colonization
During the Dutch colonization, the Dutch formed Tapanuli Residency in 1910. The Tapanuli Residency is divided into four regions that is called afdeling ; and today it is known as regency or city, namely:-
Afdeling Sibolga and Ommnenlanden, today it is Central Tapanuli Regency and Sibolga.
Afdeling Bataklanden, which later became North Tapanuli Regency, Humbang Hasundutan Regency, Toba Samosir Regency, Samosir Regency, Dairi Regency and Pakpak Bharat Regency.
After the independence, the government of Indonesia retain Tapanuli as Residency. Dr. Ferdinand Lumban Tobing became the first Tapanuli Resident. Although there were changes made to the name, but the division of the region was still the same. For example, the name of Afdeling Bataklanden was changed to Luhak Tanah Batak and the first luhak appointed was Cornelius Sihonbing; who was once also a Demang Silindung. The title Onderafdeling is also changed to urung, and demangs that surpervises onderafdeling are promoted as kepala urung. Onderdistrik then became urung kecil, and is supervised by kepala urung kecil; which was previously known as assistant demang. Just as it was in the past, the government of the Tapanuli Residency were divided into four districts, namely:-
During the transfer of sovereignty in early 1950s, the Tapanuli Residency that was unified into North Sumatra province were divided into four new regencies, namely:-
In December 2008, the Tapanuli Residency was unified under North Sumatra province. At the moment, Toba is under the Toba Samosir Regency's region with Balige as its capital.
Culture
The Toba people practices a distinct culture. It is not a must for Toba people to live in Toba region, although their origin is from Toba. Just as it is with other ethnicities, the Toba people have also migrated to other places to look for better life. For example, majority of the Silindung natives are the Hutabarat, Panggabean, Simorangkir, Hutagalung, Hutapea and Lumbantobing clans. Instead all those six clans are actually descendants of Guru Mangaloksa, one of Raja Hasibuan's sons from Toba region. So it is with the Nasution clan where most of them live in Padangsidimpuan, surely share a common ancestor with their relative, the Siahaan clan in Balige. It is certain that the Toba people as a distinct culture can be found beyond the boundaries of their geographical origins. The region of Toba, known as "the king of Batak" is precisely Sianjur village situated on the slopes of Mount Pusuk Buhit, about 45 minutes drive from Pangururan, the capital of Samosir Regency today.
The Toba clan
or family name is part of a Toba person's name, which identifies the family they belong. The Batak people always have a surname or family name. The surname or family name is obtained from the father's lineage which would then be passed on to the offspring continuously. Pardede, Napitupulu, Panggabean, Siahaan, Sihombing, Sitorus, Pandjaitan, Marbun, Lumban Tobing, Aritonang, Pangaribuan, Hutapea and Simatupang are popular surnames.
Traditional house
The traditional house of the Toba people is called Rumah Bolon. It is a rectangular building that can house up to five or six families. One can enter a Rumah Bolon through a staircase in the middleof the house with odd numbers of steps. When a person enters the house, one must bow in order to avoid one's head from knocking the transverse beam at the entrance of the traditional house. The interpretation of this is that the guests must respect the owner of the house.
Views of Toba people in Indonesian culture
The Batak Toba are known throughout Indonesia as capable musicians, and are perceived as confident, outspoken and willing to question authority, expressing differences in order to resolve them through discussion. This outlook on life is contrasted to Javanese people, Indonesia's largest ethnic group, who are more culturally conciliatory and less willing to air differences publicly.
