Sarawak is a state of Malaysia. The largest among the 13 states, with an area almost equal to that of Peninsular Malaysia, Sarawak is located in northwest Borneo Island, and is bordered by the Malaysian state of Sabah to the northeast, Kalimantan (the Indonesian portion of Borneo) to the south, and Brunei in the north. The capital city, Kuching, is the largest city in Sarawak, the economic centre of the state, and the seat of the Sarawak state government. Other cities and towns in Sarawak include Miri, Sibu, and Bintulu. As of the 2020 Malaysia census, the population of Sarawak was 2.45 million. 

Sir James Brooke, Rajah of Sarawak (29 April 1803 – 11 June 1868), was a British soldier and adventurer who founded the Raj of Sarawak in Borneo. He ruled as the first White Rajah of Sarawak from 1841 until his death in 1868. Brooke was born and raised during the Company Raj of the British East India Company in India. After a few years of education in England, he served in the Bengal Army, was wounded, and resigned his commission. He then bought a ship and sailed out to the Malay Archipelago where, by helping to crush a rebellion, he became governor of Sarawak. He then vigorously suppressed piracy in the region and, in the ensuing turmoil, restored the Sultan of Brunei to his throne, for which the Sultan made Brooke the Rajah of Sarawak. He ruled until his death.
