The history of Singapore began when Singapore was expelled from Malaysia and became an independent republic on 9 August 1965. After the separation, the fledgling nation had to become self-sufficient, and faced problems including mass unemployment, housing shortages and lack of land and natural resources such as petroleum.

During Lee Kuan Yew's term as prime minister from 1959 to 1990, his administration curbed unemployment, raised the standard of living and implemented a large-scale public housing programme. The country's economic infrastructure was developed, racial tension was eliminated and an independent national defence system was created. Singapore evolved from a dying nation to first world status towards the end of the 20th century.In 1990, Goh Chok Tong succeeded Lee as Prime Minister. During his tenure, the country tackled the economic impacts of the 1997 Asian financial crisis and the 2003 SARS outbreak, as well as terrorist threats posed by the Jemaah Islamiah (JI) post11 September and the Bali bombings. In 2004 Lee Hsien Loong, the eldest son of Lee Kuan Yew, became the third prime minister.

Singapore ( (listen)), officially the Republic of Singapore, is a sovereign island city-state in maritime Southeast Asia. It lies about one degree of latitude (137 kilometres or 85 miles) north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Riau Islands (Indonesia) to the south, and the South China Sea to the east. The country's territory is composed of one main island, 63 satellite islands and islets, and one outlying islet, the combined area of which has increased by 25% since the country's independence as a result of extensive land reclamation projects. It has the third greatest population density in the world. With a multicultural population and recognising the need to respect cultural identities, Singapore has four official languages; English, Malay, Mandarin, and Tamil. English is the lingua franca. Multiracialism is enshrined in the constitution and continues to shape national policies in education, housing, and politics.

Modern Singapore was founded in 1819 by Sir Stamford Raffles as a trading post of the British Empire. In 1867, the colonies in Southeast Asia were reorganised and Singapore came under the direct control of Britain as part of the Straits Settlements. During the Second World War, Singapore was occupied by Japan in 1942, and returned to British control as a separate crown colony following Japan's surrender in 1945. Singapore gained self-governance in 1959 and in 1963 became part of the new federation of Malaysia, alongside Malaya, North Borneo, and Sarawak. Ideological differences led to Singapore being expelled from the federation two years later and it became an independent country.

After early years of turbulence and despite lacking natural resources and a hinterland, the nation rapidly developed to become one of the Four Asian Tigers based on external trade, becoming a highly developed country; it is ranked ninth on the UN Human Development Index and has the second-highest GDP per capita (PPP) in the world. Singapore is the only country in Asia with a AAA sovereign rating from all major rating agencies. It is a major financial and shipping hub, has consistently ranked the most expensive city to live in since 2013, and has been identified as a tax haven. Singapore is placed highly in key social indicators: education, healthcare, quality of life, personal safety, and housing, with a home-ownership rate of 91 percent. Singaporeans enjoy one of the longest life expectancies, fastest Internet connection speeds, lowest infant mortality rates and lowest levels of corruption in the world.Singapore is a unitary parliamentary republic with a Westminster system of unicameral parliamentary government. While elections are considered generally free, the government exercises significant control over politics and society, and the People's Action Party has ruled continuously since independence. One of the five founding members of ASEAN, Singapore is also the headquarters of the Asia-Pacific Economic Cooperation (APEC) Secretariat, the Pacific Economic Cooperation Council (PECC) Secretariat, and many international conferences and events. Singapore is also a member of the United Nations, World Trade Organization, East Asia Summit, Non-Aligned Movement, and the Commonwealth of Nations.
