Long ago, Singapore joined a big group called Malaysia.
Long ago, Singapore joined Malaysia.
Leaders wanted to work together. They hoped to keep things safe. Singapore had its own rules for schools.
But the two sides had fights. They disagreed about money and power. This caused many problems.
Soon, the leaders decided to split. Singapore became its own country.
Now, Singapore is a place all on its own.
Singapore was a small island with many people. For a time, it was part of a country called Malaysia.
In 1963, several places joined to form Malaysia. This included Malaya, Sabah, Sarawak, and Singapore. Leaders wanted them to work together. They hoped to stop the spread of communist ideas. Singapore had some special rules. It could make its own rules for schools and jobs. But the main government in Kuala Lumpur handled defense. 
Soon, the two sides had many fights. They disagreed about taxes and money. There were also fights between different groups of people. These problems made it hard to work together. The leader of Malaysia, Tunku Abdul Rahman, decided to separate the two.
On August 9, 1965, Singapore became its own country. This was a big change. Even after they split, they still shared some things. They used the same airlines and even the same money for a while. Later, they each had their own ways of doing things.
Singapore is a small island with a very large population. For a short time in history, it was a state within a bigger country called Malaysia.
To form Malaysia, several different lands had to join together. The Federation of Malaya merged with Singapore and two other places called North Borneo and Sarawak. 
Making this union work was not easy for the leaders. The People's Action Party, or PAP, led the government in Singapore. The Alliance Party led the government in Malaysia. Even though they had an agreement to stay out of each other's politics, tensions grew. There were disagreements about taxes and how much money Singapore should give to the federal government. The central government even threatened to raise Singapore's contribution from 40 to 60 percent. These political fights made the relationship between the two governments very strained.
Other problems arose between the different groups of people living in Singapore. There were racial and economic conflicts that led to race riots in 1964. This was a very hard time for the community. Because of these many disagreements, the Malaysian prime minister, Tunku Abdul Rahman, decided to separate the two. He worked with Singapore's finance minister, Goh Keng Swee, to make this happen. They signed the Separation Agreement on 7 August 1965. On 9 August 1965, Singapore officially became its own sovereign state.
Even after the split, the two nations stayed connected in some ways. For a while, they shared a national airline. It was called Malaysia–Singapore Airlines from 1966 until 1971. 
The State of Singapore refers to a specific period in history when Singapore was a member of Malaysia. This era lasted from 16 September 1963 to 9 August 1965. During this time, Singapore was one of 14 states within the Malaysian federation. It was the smallest state by land area. However, it held the largest population with 1.82 million people. This period was defined by complex political negotiations and efforts to balance local autonomy with national unity.
The formation of Malaysia involved a major merger of several territories. The Federation of Malaya joined with Singapore and the Borneo territories of Sabah and Sarawak. British, Malayan, and Singaporean leaders supported this merger to counter communist influence in Southeast Asia. This strategy was part of a larger British plan called the "Grand Design." The goal was to maintain influence during decolonization while ensuring regional security. The merger was formalized through the Malaysia Agreement and a 1962 integration referendum.
Singapore operated under a system of high autonomy within the federation. The Federal Government in Kuala Lumpur managed defense and external affairs. In contrast, Singapore maintained control over education and labor laws. To manage political representation, Singapore was allocated 15 seats in the Dewan Rakyat, which is the federal parliament. A reciprocal arrangement also existed between the two sides. This meant citizens could not vote in or contest elections in the other's territory. These rules aimed to protect Singapore's autonomy while limiting the political influence of its Chinese-majority population.
Political leadership played a central role in the merger and its eventual end. In Singapore, the People's Action Party (PAP) led the government after the 1959 election. Lee Kuan Yew was the leader of the PAP and a strong advocate for the merger. In Malaysia, the Alliance Party held power. Despite a "tacit agreement" to avoid interfering in each other's politics, tensions rose quickly. The Singapore branch of the Alliance contested the 1963 elections in Singapore. Later, the PAP contested the 1964 federal elections in Malaysia. These actions challenged the established political boundaries between the two governments.
Economic and social conflicts further strained the relationship between Singapore and the federal government. Disagreements arose regarding tax proposals and development loans for Sabah. The federal government even threatened to raise Singapore's revenue contribution from 40 to 60 percent. Social tensions also emerged between the Malay and Chinese populations. These communal tensions resulted in race riots in 1964. These events made the political situation increasingly unstable for both the PAP and the Alliance Party. 
To resolve these deep disagreements, the Malaysian Prime Minister, Tunku Abdul Rahman, decided to separate Singapore from the federation. This decision was supported by Singapore's finance minister, Goh Keng Swee, and some PAP leaders. The Separation Agreement was signed on 7 August 1965. On 9 August 1965, Singapore officially became a sovereign state. For a long time, the public believed Singapore had been abruptly expelled. However, the release of the Albatross file in December 2025 provided more detail about the actual negotiations. This file contained the records of Goh Keng Swee regarding the separation talks.
Even after the separation, the two nations maintained several functional connections. For several years, they shared a national carrier called Malaysia–Singapore Airlines. This airline operated under that name from 1966 until it split in 1971.
