At the conclusion of the Vietnam War on 30 April 1975, the city came under the control of the Vietnamese People's Army.Among Vietnamese diaspora communities and particularly the U. (which had fought the communists), this event is commonly called the "fall of Saigon", while the Socialist Republic of Vietnam refers to it as the "Liberation of Saigon".In 1956, after South Vietnam's independence from France in 1955, the région of Saïgon–Cholon became a single city called Saïgon following the merger of the two cities of Saïgon and Cholon.
The former name Saigon is still widely used by many Vietnamese, especially in informal contexts.
A large Vauban citadel called Gia Định was built Conquered by France and Spain in 1859, the city was influenced by the French during their colonisation of Vietnam, and a number of classical Western-style buildings and French villas in the city reflect this.
Saigon had, in 1929, a population of 123,890, including 12,100 French.
Following the death of Franklin Roosevelt and the abandonment of anti-colonialist policies the U. supported France in regaining its control over the country, with effective control spanning mostly in the Southern half and parts of the Red River Delta region like Hanoi, Haiphong and Thái Bình.
Former Emperor Bảo Đại made Saigon the capital of the State of Vietnam in 1949 with himself as head of state.
