Inhabitants of the Malaysian peninsula and the island of Singapore first migrated to the area between 2500 and 1500 B.C.. British and Dutch interest in the region grew with the spice trade, and the trading post of Singapore was founded in 1819 by Sir Stamford Raffles. It was made a separate Crown colony of Britain in 1946, when the former colony of the Straits Settlements was dissolved. The other two settlements on the peninsula—Penang and Malacca—became part of the Union of Malaya, and the small island of Labuan was transferred to North Borneo. The Cocos (or Keeling) Islands and Christmas Island were transferred to Australia in 1955 and in 1958, respectively.

Singapore attained full internal self-government in 1959, and Lee Kwan Yew, an economic visionary with an authoritarian streak, took the helm as prime minister. On Sept. 16, 1963, Singapore joined Malaya, Sabah (North Borneo), and Sarawak in the Federation of Malaysia. It withdrew from the Federation on Aug. 9, 1965, and a month later proclaimed itself a republic.

Under Lee, Singapore developed into one of the cleanest, safest, and most economically prosperous cities in Asia. However, Singapore's strict rules of civil obedience also drew criticism from those who said the nation's prosperity was achieved at the expense of individual freedoms.

S. R. Nathan was declared president without an election when he was certified as the only candidate eligible to run in 1999 elections. Prime Minister Goh resigned in August 2004, and Lee Hsien Loong became the country's third premier since it gained independence from Britain in 1965.

For 140 years (1819-1959), the Union Jack flew over Singapore. Then, on 3 December 1959, the National Flag, an important symbol of independence, was unveiled at the installation of the new Head of State, the Yang di-Pertuan Negara. Also unveiled that day were the State Crest and the National Anthem. The flag was conceived and created by a committee headed by the then Deputy Prime Minister, Dr Toh Chin Chye.
