Inconfidência Mineira was an unsuccessful separatist movement in Brazil in 1789. It was the result of a confluence of external and internal causes in what was then colonial Brazil. The external inspiration was the independence of thirteen British colonies in North America following the American Revolutionary War, a development that impressed the intellectual elite of particularly the captaincy of Minas Gerais.

Minas Gerais is one of the 27 federative units of Brazil, being the fourth largest state by area and the second largest in number of inhabitants with a population of 20,539,989 according to the 2022 census. Located in the Southeast Region of the country, it is limited to south and southwest with São Paulo; Mato Grosso do Sul to the west; Goiás and the Federal District to the northwest; Bahia to the north and northeast; Espírito Santo to the east; and Rio de Janeiro to the southeast. The state's capital and largest city, Belo Horizonte, is a major urban and finance center in Brazil, being the sixth most populous municipality in the country while its metropolitan area ranks as the third largest in Brazil with just over 5.8 million inhabitants, after those of São Paulo and Rio de Janeiro. Minas Gerais' territory is subdivided into 853 municipalities, the largest number among Brazilian states.
