The name Samarinda originates from the description of the way in which the Bugis houses were constructed. At that time houses were customarily built on a raft and generally had the same height. This provided important social symbolism of equality between residents; no person's house, and thus no person, was seen as higher or lower than another. They named the settlement “Samarenda”, meaning “equally low”. After hundreds of years of use the pronunciation of the name changed slightly and the city became known as Samarinda.
At the start of the Gowa War, the Dutch under Admiral Speelman's command attacked Makassar from the sea. Meanwhile, the Netherlands' Bugis ally Arung Palakka led a ground attack. The Kingdom of Gowa was forced to surrender and Sultan Hasanuddin was made to sign the Treaty of Bongaja on 19 November 1667.
The treaty did not quell all trouble for the Dutch however, since the Bugis from Gowa continued their struggle using guerilla tactics.
