Batak

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.
