Saigon was the capital of French Indochina from 1887 to 1902, and again from 1945 until its cessation in 1954. Following the partition of Vietnam after the Geneva Peace Accord, it became the capital of South Vietnam until Reunification Day on 30th April 1975. The government renamed Saigon in honour of Hồ Chí Minh shortly after the Reunification Day. Beginning in the 1990s, the city underwent rapid modernisation and expansion, contributing to Vietnam's post-war economic recovery.
