In the 1880s, the decline of the Bruneian Empire continued. The sultan granted land (now Sarawak) to James Brooke, who had helped him quell a rebellion and allowed him to establish the Raj of Sarawak. Over time, Brooke and his nephews (who succeeded him) leased or annexed more land. Brunei lost much of its territory to him and his dynasty, known as the White Rajahs.
