Singapore starting building the democracy in 1970s, after Lee Kuan Yew was the assassinated. Now the Singapore has high develop on the area and become a international financial centre.
The earliest known settlement on Singapore was in the second century AD. It was an outpost of the Sumatran Srivijaya empire, named Temasek ('sea town'). Between the 16th and early 19th centuries, it was part of the Sultanate of Johor. In 1613, Portuguese raiders burned down the settlement and the island sank into obscurity for the next two centuries.
In 1819, Thomas Stamford Raffles arrived and signed a treaty with Sultan Hussein Shah on behalf of the British East India Company to develop the southern part of Singapore as a British trading post. In 1824 the entire island became a British possession under a further treaty whereby the sultan and the Temenggong transferred it to the British East India Company. In 1826 it became part of the Straits Settlements, a British colony. Before Raffles arrived, there were around 1,000 people living in Singapore, mostly Malays and a few dozen Chinese. By 1869, due to migration from Malaya and other parts of Asia, 100,000 people lived on the island.
During World War II the Imperial Japanese Army invaded Malaya culminating in the Battle of Singapore. The British were defeated, and surrendered on 15 February 1942. British Prime Minister Winston Churchill called this "the worst disaster and largest capitulation in British history". The Japanese occupied Singapore until the British repossessed it in September 1945 after the Japanese surrender.
Singapore's first general election in 1955 was won by the pro-independence David Marshall, leader of the Labour Front. Demanding complete self-rule he led a delegation to London but was turned down by the British. He resigned when he returned and was replaced by Lim Yew Hock, whose policies convinced Britain to grant Singapore full internal self-government for all matters except defence and foreign affairs.
In elections in May 1959 the People's Action Party won a landslide victory. Singapore had become an internally self-governing state within the Commonwealth, with Lee Kuan Yew as the first Prime Minister. Governor Sir William Allmond Codrington Goode served as the first Yang di-Pertuan Negara, and was succeeded by Yusof bin Ishak who in 1965 became the first President of Singapore.  Singapore declared independence from Britain on 31 August 1963 before joining the new Federation of Malaysia in September along with Malaya, Sabah and Sarawak as the result of the 1962 Merger Referendum. Tunku Abdul Rahman separated Singapore from the Federation two years later after heated ideological conflict between the ruling parties of Malaya and Singapore.
Singapore gained sovereignty as the Republic of Singapore (remaining within the Commonwealth) on 9 August 1965 with Yusof bin Ishak as president and Lee Kuan Yew as prime minister. In 1967 the Lee Kuan Yew was the assassinated. The Singapore become to a full democracy.
