The history of Campeonato Mineiro can be divided into two parts: before and after the construction of the Mineirão, in September 1966.

This is partly because in the early 20th century Brazil did not have a well established transportation and communication infrastructure, that could help it organize a national league in the country, which was made worse by the nation's enormous size.

Reinaldo, Cerezo, Éder, Ronaldo, Dario and Tostão had their professional football debut in the competition.

a: In 2002, the three main clubs in Minas Gerais (América, Atlético and Cruzeiro) plus Mamoré did not take part in the Campeonato Mineiro, because they were competing in the Copa Sul-Minas.

Because of this, the Minas Gerais football body created a short tournament called the ‘Supercampeonato Mineiro’ bringing these four teams together with Caldense, winners of the 2002 Mineiro championship.
