바오다이
The Japanese ousted the Vichy French administration in March 1945 and then ruled through Bảo Đại, who renamed his country "Vietnam". He abdicated in August 1945 when Japan surrendered. From 1949 to 1955, Bảo Đại was the chief of state of the State of Vietnam (South Vietnam). Viewed as a puppet ruler, Bảo Đại was criticized for being too closely associated with France and spending much of his time outside Vietnam. He was eventually ousted in a referendum vote in 1955 by Prime Minister Ngô Đình Diệm, who was supported by the United States.
