Pasaman is located in the north of West Sumatra. The town of Bonjol, birthplace of Tuanku Imam Bonjol, is notable for being the area where the Trans-Sumatran Highway crosses the equator. Although the majority ethnic group in West Sumatra is Minangkabau, in Pasaman Regency there is another substantial ethnic group, the Mandailing from North Sumatra; this is particularly true of the most northern districts within the regency which together form a geographical projection into North Sumatra, namely Rao, Rao Utara, Rao Selatan and Mapat Tunggul Districts. Consequently the name "Pasaman" means "equality" between the two groups in the Minangkabau language (Indonesian: Persamaan). The first Vice-Regent of Pasaman was H. Ahmad Dahlan Nasution from Duo Koto, King of Sontang (kingdom of Mandailing in Pasaman).
