Campeonato Mineiro is the state football league of the state of Minas Gerais and is controlled by the Minas Gerais Football Federation FMF (Federação Mineira de Futebol). The history of Campeonato Mineiro can be divided into two parts: before and after the construction of the Mineirão, in September 1966. The Mineirão is the biggest soccer stadium of Minas Gerais and it is located in Minas Gerais' state capital, Belo Horizonte. Before the stadium's inauguration América and Atlético were the most successful teams in the state, but after the construction of the Mineirão, known as the "Era Mineirão" ("Mineirão Era"), another team from the capital, Cruzeiro, also gained prominence. Atlético is the most successful team in the competition, having won 43 championships as of 2015.
