and journalists, teachers, economists, scientists, and military officers. Important figures such as local king (Sisingamangaraja XII), two Indonesian prime ministers (Amir Syarifuddin Harahap, Burhanuddin Harahap), speakers of the parliament (Zainul Arifin Pohan, Akbar Tanjung), one vice president (Adam Malik Batubara), two governors of the central bank (Darmin Nasution, Arifin Siregar), one attorney general (Marsillam Simanjuntak), and many influential cabinet ministers (Albert Mangaratua Tambunan, Ferdinand Lumbantobing, Luhut Binsar Pandjaitan, M.S.

Although the Batak are a minority among the Indonesian population (3.58%; only 8–9 million Batak people out of 236 million according 2010's census), a large number of notable Batak have achieved prominent places in the Indonesian history.
