Ho Chi Minh City History 2026: Saigon from French Colony to Reunification

Ho Chi Minh City’s history moves from Khmer fishing settlement through French colonial capital, American War base, and postwar rapid growth into Vietnam’s commercial engine.

Before French Colonialism

The land now occupied by HCMC was part of the Khmer Empire until the 17th century, when Nguyen lords began moving Vietnamese settlers south into the Mekong Delta. By the 18th century, the settlement of Prey Nokor (the Khmer name) had been absorbed into Vietnamese territory and renamed Gia Dinh.

Gia Dinh was the base from which Nguyen Anh (later Emperor Gia Long) fought to unify Vietnam, with French military support, in the late 18th century.

French Indochine (1859–1945)

France captured Gia Dinh in 1859, establishing Saigon as the administrative capital of French Cochinchina. The French transformed the city systematically: wide boulevards (modelled on Paris), drainage canals, administrative buildings (the current Reunification Palace site, Notre-Dame Cathedral, the Central Post Office), and the port infrastructure that made Saigon one of the most important commercial cities in Southeast Asia.

The rice trade from the Mekong Delta, processed through Saigon’s mills and exported through its port, made the city wealthy. The French colonial quarter — the buildings of which still stand throughout Districts 1 and 3 — was designed to project permanence and European civilisation.

The American War period (1955–1975)

After the 1954 Geneva Accords, Vietnam was temporarily divided at the 17th parallel. South Vietnam, with Saigon as its capital, was supported by the United States as a bulwark against communist expansion.

The American military presence transformed Saigon — the city accommodated tens of thousands of US service members and civilian contractors, their money flooding into bars, hotels, and services along Tu Do Street (now Dong Khoi). The city’s population swelled with refugees from the countryside.

The 1968 Tet Offensive included an assault on Saigon itself — Viet Cong forces briefly occupied the US Embassy compound. The footage was broadcast globally and fundamentally changed American public opinion about the war.

The Fall of Saigon (April 30, 1975)

North Vietnamese forces entered Saigon on April 30, 1975. A tank crashed through the Reunification Palace gates — the iconic image of the war’s end. The US evacuation by helicopter from the embassy roof the previous day (April 29) is one of the most photographed events of the 20th century.

The city was renamed Ho Chi Minh City in 1976 after reunification, though most Vietnamese and nearly all foreigners continue to call it Saigon informally.

Post-reunification to the present

The immediate post-1975 period was economically difficult — the Doi Moi economic reforms of 1986 opened Vietnam to market economics and foreign investment. HCMC responded faster than Hanoi, its commercial culture adapting quickly to the new environment.

From the 1990s onward, HCMC grew rapidly. The city of 3 million in 1980 had grown to over 9 million by the 2020s, with the greater metropolitan area significantly larger. The skyline, dominated by French colonial buildings in 1975, now has dozens of high-rise towers.
