North Borneo Chartered Company in the context of "Governor of North Borneo"

Sabah (Malay pronunciation: [ˈsabah]) is a state of Malaysia located in northern Borneo, in the region of East Malaysia. Sabah has land borders with the Malaysian state of Sarawak to the southwest and Indonesia's North Kalimantan province to the south. The Federal Territory of Labuan is an island just off Sabah's west coast. Sabah shares maritime borders with Vietnam to the west and the Philippines to the north and east. Kota Kinabalu is the state capital and the economic centre of the state, and the seat of the Sabah State government. Other major towns in Sabah include Sandakan and Tawau. The 2020 census recorded a population of 3,418,785 in the state. It has an equatorial climate with tropical rainforests, abundant with animal and plant species. The state has long mountain ranges on the west side which forms part of the Crocker Range National Park. Kinabatangan River, the second longest river in Malaysia runs through Sabah. The highest point of Sabah, Mount Kinabalu is also the highest point of Malaysia.

The earliest human settlement in Sabah can be traced back to 20,000–30,000 years ago along the Darvel Bay area at the Madai-Baturong caves. The state has had a trading relationship with China starting from the 14th century AD. Sabah came under the influence of the Bruneian Empire in the 14th and 15th centuries. The state was subsequently acquired by the British North Borneo Chartered Company in the 19th century. During World War II, North Borneo was occupied by the Japanese for three years. It became a British Crown Colony in 1946. On 31 August 1963, the newly-renamed Sabah was granted self-governance by the British. Following this, Sabah became one of the founding members of the Federation of Malaysia (established on 16 September 1963) alongside the Crown Colony of Sarawak, the Colony of Singapore (expelled in 1965), and the Federation of Malaya (Peninsular Malaysia or West Malaysia). The federation was opposed by neighbouring Indonesia, which led to the Indonesia–Malaysia confrontation over three years along with the threats of annexation by the Philippines along with the Sultanate of Sulu, threats which continue to the present day.

Kota Kinabalu (Malaysian: [ˈkota kinaˈbalu]; formerly known as Jesselton), colloquially referred to as KK, is the state capital of Sabah, Malaysia. It is also the capital of the Kota Kinabalu District as well as the West Coast Division of Sabah. The city is located on the northwest coast of Borneo facing the South China Sea. The Tunku Abdul Rahman National Park lies to its west and Mount Kinabalu, which gave the city its name, is located to its east. Kota Kinabalu has a population of 452,058 according to the 2010 census; when the adjacent Penampang and Tuaran districts are included, the metro area has a combined population of 628,725. The 2020 Census revealed an increase in the municipal population to 500,421, while the wider area including the Penampang and Putatan districts had a population of 731,406.

Historically, the Kadazandusuns called the area by the name of Dondoung. In the 15th century, the area of Kota Kinabalu was under the influence of Bruneian Empire. In the 19th century, the British North Borneo Chartered Company (NBCC) first set up a settlement near the Gaya Island. However, it was destroyed by fire in 1897 by a local leader named Mat Salleh. In July 1899, the place located opposite to the Gaya Island was identified as a suitable place for settlements. Development in the area was started soon after that; and the place was named "Api-api" before it was renamed after Sir Charles Jessel, the vice-chairman of NBCC, as "Jesselton". Jesselton became a major trading port in the area, and was connected to the North Borneo Railway. Jesselton was largely destroyed during World War II. The Japanese occupation of Jesselton provoked several local uprisings notably the Jesselton Revolt but they were eventually defeated by the Japanese. After the war, NBCC was unable to finance the high cost of reconstructions and the place was ceded to the British Crown Colony. The British Crown declared Jesselton as the new capital of North Borneo in 1946 and started to rebuild the town. After the formation of Malaysia, North Borneo was renamed as Sabah. In 1967, Jesselton was renamed as Kota Kinabalu, Kota being the Malay word for City and Kinabalu after the nearby Mount Kinabalu. Kota Kinabalu was granted city status in 2000.

Tawau (Malaysian: [ˈta wau]), formerly known as Tawao, is the capital of the Tawau District in Sabah, Malaysia. It is the third-largest city (or town) in Sabah, after Kota Kinabalu and Sandakan. It is located on the Semporna Peninsula in the southeast coast of the state in the administrative centre of Tawau Division, which is bordered by the Sulu Sea to the east, the Celebes Sea to the south at Cowie Bay and shares a border with North Kalimantan, Indonesia. The town had an estimated population as of 2010, of 113,809, while the whole municipality area had a population of 397,673 (including 47,466 in Kalabakan, subsequently split off to form a separate district). The municipal area had a population of 372,615 at the 2020 Census.

Before the founding of Tawau, the region around it was the subject of dispute between the British and Dutch spheres of influence. In 1893, the first British merchant vessel sailed into Tawau, marking the opening of the town's seaport. In 1898, the British set up a settlement in Tawau. The North Borneo Chartered Company (BNBC) accelerated growth of the settlement's population by encouraging the immigration of Chinese. Consequent to the Japanese occupation of North Borneo, the Allied forces bombed the town in mid-1944, razing it to the ground. After the Japanese surrender in 1945, 2,900 Japanese soldiers in Tawau became prisoners of war and were transferred to Jesselton. Tawau was rebuilt after the war, and by the end of 1947, the economy was restored to its pre-war status. Tawau was also the main point of conflict during the Indonesia–Malaysia confrontation from 1963 to 1966. During that period, it was garrisoned by the British Special Boat Section, and guarded by Australian Destroyers and combat aircraft. In December 1963, Tawau was bombed twice by Indonesia and shootings occurred across the Tawau-Sebatik Island international border. Indonesians were found trying to poison the town's water supply. In January 1965, a curfew was imposed to prevent Indonesian attackers from making contact with Indonesians living in the town. While in June 1965, another attempted invasion by the Indonesian forces was repelled by bombardment by an Australian destroyer. Military conflict finally ended in December 1966.
