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.
Self-governance of Singapore
In 1963, Singapore joined Malaysia, relieving it of colonial rule and becoming an autonomous state within the Malaysian federation. After a fallout in the relations between the United Malays National Organisation (UMNO) and the People's Action Party (PAP), the ruling parties of the Federation and Singapore respectively, full independence came about with Singapore's expulsion from Malaysia in 1965.
