Raja Muda Hashim, the uncle of Omar Ali Saifuddin II, Sultan of Brunei, conceded land to the British adventurer James Brooke (pictured) to establish the Raj of Sarawak.

Omar Ali Saifuddin II was the 23rd Sultan of Brunei from 1828 until his death in 1852. During his reign, Western powers such as the United Kingdom and the United States visited the country. His reign saw the British adventurer James Brooke becoming the White Rajah of Sarawak.

The Sultanate of Brunei or simply Brunei, also known as the Bruneian Empire, was a Malay sultanate centered around Brunei on the northern coast of Borneo in Southeast Asia. Brunei became a sovereign state around the 15th century, when it substantially expanded after the fall of Malacca to the Portuguese, extending throughout coastal areas of Borneo and the Philippines, before it declined in the 17th and 18th centuries. It became a British protectorate in the 19th century.

James Brooke, 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.

The Raj of Sarawak, Kingdom of Sarawak or State of Sarawak, was a kingdom founded in 1841 in northwestern Borneo and was in a treaty of protection with the United Kingdom from 1888. It was formed from a series of land concessions acquired by the Englishman James Brooke from the Sultan of Brunei. Sarawak was recognised as a sovereign state by the United States in 1850, and by the United Kingdom in 1864. Since the formation of Malaysia on 16 September 1963, The Raj has been a constituent state of Malaysia as the state of Sarawak.
