Antasari was born in 1797. He was a prince from a line of the royal family. Because Antasari wanted to repel the Dutch, he cooperated with the leaders of Martapura, Kapuas, Pelaihari, Barito, and Kahayan. On 18 April 1859, the Banjarmasin War broke out between Antasari's alliance, which was able to field some 6,000 armed men, and the Dutch. The war took place mainly in South and Central Kalimantan. Antasari's forces attacked the Dutch in Gunung Jabuk and also the Dutch coal mines in Pengaron. Meanwhile, his allies attacked other Dutch posts. They also attacked Dutch ships when they sank the ship Onrust in December 1859. The Dutch had attempted to make Antasari surrender and end the war by offering him wealth and power in exchange for his surrender, but Antasari rejected to negotiate. In early August 1860, Antasari's forces were in Ringkau Katan. They were defeated in a battle on 9 August, after Dutch reinforcements had arrived from Amuntai. Antasari, together with Prince Miradipa and Tumenggung Mancanegara, defended Tundakar fort on 24 September 1861. He also defended a fort in Mount Tongka on 8 November 1861 with Gusti Umar and Tumenggung Surapati. In October 1862, Antasari was planning a big attack. However, an outbreak of smallpox led to his death on 11 October 1862.​
