Clube Atlético Mineiro (Brazilian Portuguese: [ˈklubi aˈtlɛtʃiku miˈneɾu]), commonly known as Atlético Mineiro or Atlético, and colloquially as Galo (pronounced [ˈgalu], "Rooster"), is a professional football club based in Belo Horizonte, Minas Gerais, Brazil. The team competes in the Campeonato Brasileiro Série A, the first level of Brazilian football, as well as in the Campeonato Mineiro, the top tier state league of Minas Gerais. Atlético Mineiro is the oldest active football club in Minas Gerais, founded on 25 March 1908 by twenty-two students from Belo Horizonte. Despite having liberal, upper-class founders, the club opened its doors to players of every social class, establishing itself as a "people's club", and becoming one of the most-supported clubs in Brazil. The club's mascot, a rooster, has been strongly associated with Atlético since its introduction in the 1930s. Over the years, the word galo (Portuguese for "rooster") became a common nickname for the club itself. The team's regular home kit comprises black-and-white striped shirts, with black shorts and white socks.
