Banjermassin, Or Banjarmassin. I. A large state of S. E. Borneo, governed by a sultan subordinate to the Dutch government; pop. vaguely estimated at about 300,000, nearly all Mohammedans. It borders on the strait of Macassar, and is bounded W. by the Banjer river. A range of mountains, some of them over 3,000 ft. high, runs through the district. Iron, diamonds, and excellent coal are found, and the natives are noted for their skill in making all kinds of arms. Pepper is the most important product of the soil. The trade is controlled by the Chinese. The Dutch settled here in 1747, and in 1787 made a treaty with the sultan by which their supremacy was recognized in consideration of their aid in repelling an invasion from Celebes. The British East India company seized Banjermassin in 1811, but restored it in 1817. II. The chief town of the preceding state, and capital of the Dutch residency of the S. and E. coasts, situated on the left bank of the river Banjer, about 15 m. from its mouth in the Java sea; lat. 3° 23' S., Ion. 114° 37' E.; pop. about 15,000. The houses are raised on piles, the site being frequently inundated, and most of the traffic is carried on in boats. There is a fort, which encloses the Dutch resident's house, barracks, etc.
