Singapore

Historical overview

Singapore developed as a major trading port under the British Empire after the arrival of Stamford Raffles in 1819. Together with Penang and Malacca, it became part of the Straits Settlements in 1826. Its strategic position made it a significant centre of regional commerce, migration and colonial administration.

Japanese forces captured Singapore in February 1942, ending British control during the Second World War. The Japanese occupation lasted until 1945 and included severe violence, detention and the Sook Ching operation against people suspected of anti-Japanese activity. The occupation profoundly influenced post-war political consciousness and the demand for self-government.

Constitutional change accelerated in the 1950s. The Rendel Constitution took effect in 1955, creating a partly elected Legislative Assembly. The 1958 constitutional settlement provided for self-government, and the 1959 election brought the People’s Action Party to power. Lee Kuan Yew became the first prime minister of self-governing Singapore.

Singapore joined the Federation of Malaysia on 16 September 1963. Political, economic and communal tensions contributed to separation. On 9 August 1965, Singapore became an independent sovereign republic. The Proclamation of Singapore and the Republic of Singapore Independence Act 1965 are essential primary documents for the archive. Historical DevelopmentAfter independence, Singapore developed a highly centralised parliamentary system, an export-oriented economy and extensive public housing and education programmes. Its political development has also raised debates about freedom of expression, assembly, media regulation, opposition politics and the balance between public order and civil liberties.
