The State of Vietnam was a state that claimed authority over all of Vietnam during the First Indochina War although it controlled about under 5% of national territory of Vietnam. The provisional government was a brief transitional administration between colonial Cochinchina and an independent state. The state was created in 1949 and was internationally recognized in 1950, although its main power was mainly in a small part of the south, whereas the Democratic Republic of Vietnam mainly dominated almost Vietnamese territory. Former emperor Bảo Đại was chief of state (Quốc Trưởng). Ngô Đình Diệm was appointed prime minister in 1954, and after ousting Bảo Đại the following year, became president of the Republic of Vietnam.
