Sarawak, the largest state in Malaysia, is located on the South-Western corner of Malaysian Borneo. It is a land of vast primeval rainforests, majestic mountains, caves, unique flora and fauna and diverse ethnic communities. Sarawak's history is one of heroic adventure and romance, piracy and rebellion. The state came under the rule of the White Rajahs when the Sultan of Brunei made James Brook, an English adventurer, the ruler of Sarawak in 1841 for his help in quelling a rebellion. Sarawak shares its boundaries with Kalimantan in the south and Brunei and Sabah in the north. Two-thirds of its land is rainforest and its population of 1.7 million is made up of 23 ethnic groups. Sarawak is best known for its natural and cultural wonders.
