Singapore became an independent nation on 9 August 1965, when it was separated from the Federation of Malaysia after less than two years of union. The split, announced in Kuala Lumpur and Singapore on the same day, turned a small island city with no natural resources into a sovereign state under Prime Minister Lee Kuan Yew.
Background: from colony to merger
Modern Singapore began as a British trading post after the founding of Singapore by Stamford Raffles in 1819. It became a major port and naval base, was occupied by Japan after the Fall of Singapore in 1942, and returned to British rule in 1945.
In 1959 Singapore gained full internal self-government. The People’s Action Party (PAP), led by Lee Kuan Yew, won the general election, and Lee became prime minister. Lee and his colleagues believed that a small island could not survive alone and that its future lay in union with the Federation of Malaya, its economic hinterland.
Malaya’s prime minister, Tunku Abdul Rahman, was at first reluctant, because adding Singapore’s large Chinese population would change the ethnic balance of the federation. He came to support a wider union that also included the British Borneo territories of Sabah and Sarawak. Singaporeans approved merger in a referendum on 1 September 1962, and Malaysia came into being on 16 September 1963.
Two years of tension
The union was troubled from the start. Indonesia under Sukarno opposed Malaysia and launched an armed “Confrontation” against it, including bomb attacks in Singapore. Inside the federation, the PAP and the ruling Alliance, dominated by the United Malays National Organisation (UMNO), quarrelled over economic policy, revenue sharing and a proposed common market.
The deepest dispute was about the nature of the new country. The Malaysian constitution gave special rights to Malays. The PAP campaigned for a “Malaysian Malaysia”, in which citizens would be treated equally regardless of race. UMNO leaders saw this as a challenge to the Malay position, and the PAP’s decision to contest seats in mainland Malaya in the 1964 federal election deepened mistrust.
In July 1964 communal riots broke out in Singapore during a procession marking the Prophet Muhammad’s birthday, and further riots followed in September. Dozens of people were killed. In May 1965 the PAP helped form the Malaysian Solidarity Convention, an alliance of opposition parties, which alarmed the federal government further.
The separation
By mid-1965 the Tunku, who was recovering from illness in London, concluded that separation was the only way to avoid more bloodshed. Secret talks followed between his deputy Tun Abdul Razak and Singapore’s finance minister Goh Keng Swee. The separation agreement was signed on 7 August 1965.
On the morning of 9 August 1965 the Malaysian parliament passed a constitutional amendment removing Singapore from the federation, by 126 votes to none. Singapore radio broadcast a proclamation of independence the same morning. That afternoon Lee Kuan Yew held a televised press conference at which he broke down, calling the separation “a moment of anguish” because he had believed in merger all his life.
The new republic
Singapore moved quickly to establish itself. It joined the United Nations on 21 September 1965 and the Commonwealth in October. Yusof Ishak, Singapore’s head of state (Yang di-Pertuan Negara) since 1959, became the first President, and Singapore was formally constituted as a republic. The national flag and the anthem “Majulah Singapura”, adopted in 1959, became symbols of the new state.
The challenges were serious. Singapore had a population of about 1.9 million, high unemployment, no water supply of its own and little land. Its defence depended on British bases, and in 1968 Britain announced it would withdraw its forces east of Suez, a pullout largely completed by 1971. The government introduced National Service in 1967, expanded public housing through the Housing and Development Board and courted foreign manufacturers through the Economic Development Board.
Key people
- Lee Kuan Yew (1923–2015): PAP leader and prime minister from 1959 to 1990, the dominant figure of independent Singapore.
- Tunku Abdul Rahman (1903–1990): first prime minister of Malaya and Malaysia, who decided on separation.
- Goh Keng Swee (1918–2010): finance and later defence minister, who negotiated the separation terms and shaped economic policy.
- Yusof Ishak (1910–1970): first President of the Republic of Singapore.
Legacy
Relations between Singapore and Malaysia recovered over time, though disputes over water supply, land and borders continued for decades. Both countries became founding members of the Association of Southeast Asian Nations (ASEAN) in 1967.
Singapore’s later economic success made 1965 a founding story of survival against the odds. Lee’s tearful press conference is one of the most replayed scenes in the country’s history, and 9 August is celebrated each year as National Day with a parade.

Why it matters
Singapore’s separation from Malaysia created one of the world’s few modern city-states. The circumstances of its birth, a small, multiracial island suddenly on its own, shaped its emphasis on economic growth, defence and racial harmony for decades afterwards.
Frequently asked questions
When did Singapore become independent?
Singapore became an independent and sovereign state on 9 August 1965, when it separated from the Federation of Malaysia. The date is celebrated every year as Singapore's National Day.
Was Singapore expelled from Malaysia?
Malaysia's prime minister Tunku Abdul Rahman decided that Singapore should leave the federation, and the Malaysian parliament voted for separation on 9 August 1965. The separation agreement was signed by leaders of both governments on 7 August, so historians describe it as a negotiated expulsion rather than a voluntary exit.
Why did Singapore separate from Malaysia?
The main causes were political and communal tensions between Lee Kuan Yew's People's Action Party and the ruling Alliance led by UMNO. Disputes over Malay special rights, the PAP's call for a 'Malaysian Malaysia', economic disagreements and race riots in 1964 convinced the Tunku that separation was the only way to avoid further violence.
Why did Lee Kuan Yew cry in 1965?
At a televised press conference on 9 August 1965 Lee Kuan Yew broke down while explaining the separation. He had long campaigned for merger with Malaysia and called the split a moment of anguish.
How long was Singapore part of Malaysia?
Singapore was part of Malaysia for just under two years, from the federation's creation on 16 September 1963 until 9 August 1965.
