The name of Bintulu was derived from the local native language "Mentu Ulau" (picking heads). Bintulu was a small fishing village when Rajah James Brooke acquired it in 1861. Brooke later built a fort there in 1862. In 1867, the first General Council meeting (now Sarawak State Legislative Assembly) was convened in Bintulu. It is the earliest state legislature system in Malaysia. The construction of the earliest airstrip in Bintulu began in 1934 but was halted in 1938 due to financial difficulties. During World War II, the airstrip was heavily bombed by Allied forces. The British later rebuilt the airstrip, and it became fully operational in 1955. The old airport was replaced by a new airport in 2002. Bintulu remained a fishing village until 1969 when oil and gas reserves were discovered off the coast. Since then, Bintulu has become the centre of energy intensive industries such as a Malaysia LNG plant, a Shell Middle Distillate Synthesis plant, and a Bintulu combined cycle power plant. The economy has also expanded into oil palm and forest plantations, palm oil processing, wood-waste processing, and cement manufacturing. The port of Bintulu is the busiest in Sarawak. The town is also a gateway to Samalajau Industrial Park.
