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.
Names of Singapore
Vietnamese either uses the word "Singapore" or "Xin Ga Po" for the country (and "Cộng hòa Singapore" or "Cộng hòa Xin Ga Po" for "Republic of Singapore") but has traditionally used versions taken from the "hán tự" 新加坡, namely "Tân Gia Pha" or "Tân Gia Ba" (and "Tân Gia Ba Cộng hòa quốc" for "Republic of Singapore" [新加坡共和國]). It has also used such "hán tự"-derived names other for historical names including "Chiêu Nam" for "Shōnan" (昭南) and "Hạ Châu".
