The Japanese occupied Vietnam during World War II but allowed the French to remain and exert some influence. At the war's end in August 1945, a power vacuum was created in Vietnam. Capitalizing on this, the Việt Minh launched the "August Revolution" across the country to seize government offices. Emperor Bảo Đại abdicated on August 25, 1945, ending the Nguyễn dynasty. On September 2, 1945, at Duc Anh Ba Đình Square, Ho Chi Minh, leader of the Viet Minh organization, declared Vietnam's independence under the new name of the Democratic Republic of Vietnam (DRVN) in a speech that invoked the United States Declaration of Independence and the French Revolution's Declaration of the Rights of Man and of the Citizen. Ho sent several letters to the US government asking to be recognised as the government of Vietnam and offering friendship to America, but none were ever answered.
