History of Singapore
During World War 2, Singapore was conquered and occupied by the Japanese Empire from 1942 to 1945. When the war ended, Singapore reverted to British control, with increasing levels of self-government being granted, culminating in Singapore's merger with the Federation of Malaya to form Malaysia in 1963. However, social unrest and disputes between Singapore's ruling People's Action Party and Malaysia's Alliance Party resulted in Singapore's expulsion from Malaysia. Singapore became an independent republic on 9 August 1965.
Chinese Singaporeans
Following the decline of Srivijayan power, Temasek was alternately claimed by the Majapahit and the Siamese, but the invasion of 1377 and 1391 caused Singapore to be destroyed. Following that, there were little Chinese records of the visiting of Chinese to Singapore. Singapore is marked as Dan Ma Xi in the Mao Kun map that dates back to the naval voyage of Chinese explorer Zheng He in 1403. In 1420, en route the 6th voyage, Zheng He passed by Singapore, but there were no records of presence of Chinese.
