Angkola people
The Angkola people are one of the sub-ethnic groups of the Batak people, found mainly in North Sumatra, Indonesia. They primarily inhabit in the southern part of Tapanuli region. The Angkola language is similar to Mandailing language also with Toba language, but it is sociolinguistically distinct.
The name Angkola is believed to have originated from the Angkola River, which was named by an officer called Rajendra Kola who was passing through Padang Lawas and later came to power there. The southern part of the Angkola River is called Angkola Jae, while the northern part is called Angkola Julu.
The Angkola people practice patrilineal kinship, and the clans and surnames of the Angkola people are based on the patrilineal system. There are only a few Angkola surnames – Siregar, Dalimunthe, Harahap, Hasibuan, Rambe, Nasution, Daulay, Tanjung, Ritonga, Batubara, and Hutasuhut, amongst others. Angkola society strictly prohibits marriage between people with the same surname.
Most of the Angkola are Muslims, while a small minority are Christians.
