Crown Colony of Sarawak gains self-governance.

The Crown Colony of Sarawak was a British Crown colony on the island of Borneo, established in 1946, shortly after the dissolution of the British Military Administration. It was succeeded as the state of Sarawak through the formation of the Federation of Malaysia on 16 September 1963.

Self-governance, self-government, self-sovereignty or self-rule is the ability of a person or group to exercise all necessary functions of regulation without intervention from an external authority. It may refer to personal conduct or to any form of institution, such as family units, social groups, affinity groups, legal bodies, industry bodies, religions, and political entities of various degrees. Self-governance is closely related to various philosophical and socio-political concepts such as autonomy, independence, self-control, self-discipline, and sovereignty.
