Singapore ( (listen)), officially the Republic of Singapore, is a sovereign island country and 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 Singapore Strait to the south, the South China Sea to the east, and the Straits of Johor to the north. 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 highest population density in the world. With a multicultural population and recognising the need to respect cultural identities of the major ethnic groups within the nation, Singapore has four official languages: English, Malay, Mandarin, and Tamil. English is the lingua franca and numerous public services are available only in English. Multiracialism is enshrined in the constitution and continues to shape national policies in education, housing, and politics.

Singapore's history dates back at least a millennium, having been a maritime emporium known as Temasek and subsequently as a major constituent part of several successive thalassocratic empires. Its contemporary era began in 1819 when Stamford Raffles established Singapore as an entrept 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, most notably the perceived encroachment of the egalitarian "Malaysian Malaysia" political ideology led by Lee Kuan Yew into the other constituent entities of Malaysiaat the perceived expense of the bumiputera and the policies of Ketuanan Melayueventually led to Singapore's expulsion from the federation two years later; Singapore became an independent sovereign country in 1965.

After early years of turbulence whilst lacking natural resources and a hinterland, the nation rapidly developed to become one of the Four Asian Tigers based on international trade and economic globalisation, integrating itself within the world economy through free trade with minimal to no trade barriers or tariffs, export-oriented industrialisation, and the large accumulation of received foreign direct investments, foreign-exchange reserves, and assets held by sovereign wealth funds. A highly developed country, it is tied for 11th on the UN Human Development Index and has the second-highest GDP per capita (PPP) in the world. Identified as a tax haven, Singapore is the only country in Asia with a AAA sovereign credit rating from all major rating agencies. It is a major aviation, financial, and maritime shipping hub, and has consistently been ranked as one of the most expensive cities to live in for expatriates and foreign workers. Singapore is placed highly in key social indicators: education, healthcare, quality of life, personal safety, infrastructure, and housing, with a home-ownership rate of 88 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, and its legal system is based on common law. Although the country is a multi-party democracy with free elections, the government under the People's Action Party (PAP) wields significant control and dominance over politics and society. The PAP has ruled the country continuously since full internal self-government was achieved in 1959, with 83 out of 104 seats in Parliament as of the 2020 election, the rest of the seats being held by the Workers' Party (WP) and the Progress Singapore Party (PSP). 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 is the host city of 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.

The 2013 Little India riot took place on 8 December 2013 after a fatal accident occurred at SST 21:23 at the junction of Race Course Road and Hampshire Road in Little India, Singapore, causing angry mobs of passersby to attack the bus involved and emergency vehicles that had by then arrived at the location. About 300 migrant labourers were involved in the riot which lasted for around two hours. This was the second riot in post-independence Singapore, and the first in 44 years since the 1969 race riots.
