Capital Liberation Day is observed in Vietnam every October 10, commemorating the liberation of Hanoi by Viet Minh troops in 1954. The origins of this observance trace back to the end of French colonial rule, following World War II, when the Viet Minh fought for independence against both Japanese and French forces. The culmination of their struggle was marked by the Geneva Accords, which temporarily divided Vietnam at the 17th parallel, granting control of North Vietnam, including Hanoi, to the Viet Minh. The official observance of this day was established after the reunification of Vietnam in 1976, and it serves as a day of remembrance for the significant historical event in the nation's fight for independence.
