A Brief History of Singapore and its Economy
In the early 1800s, the Republic of Singapore was first established as a trading post, and soon thereafter, a colony of the British Empire. Singapore was taken over and occupied by the Japanese Army during World War II but regained its place as a British crown colony in 1945.
It became an independent nation in 1963. Following a brief two-year period as a part of the federation of Malaysia, Singapore existed as an independent country since 1965, gradually building one of the strongest economies in the Asia-Pacific region.
The government of Singapore is guided by the country’s Constitution and consists of an executive branch that includes a President and a Prime Minister, a single legislative body – the Parliament, and an independent judiciary that is composed of the Singapore Supreme Court and state courts.
