History of Singapore
During World War 2, Singapore was conquered and occupied by the Japanese Empire from 1942 to 1945. When the war ended, Singapore reverted to British control, with increasing levels of self-government being granted, culminating in Singapore's merger with the Federation of Malaya to form Malaysia in 1963. However, social unrest and disputes between Singapore's ruling People's Action Party and Malaysia's Alliance Party resulted in Singapore's expulsion from Malaysia. Singapore became an independent republic on 9 August 1965.
Colony of Singapore
The Colony of Singapore was a British Crown colony that existed from 1946 until 1963, when Singapore became part of Malaysia. When the Empire of Japan surrendered to the Allies at the end of World War II, the island was handed back to the British in 1945. In 1946, the Straits Settlements were dissolved and Singapore together with the Cocos-Keeling and Christmas islands became a separate Crown colony. The colony was governed by the British Empire until it gained partial internal self-governance in 1955.
