Guarani

Guarani Football Club was founded on April 1, 1911, in the city of Campinas, São Paulo, as Guarany Foot-Ball Club, by the initiative of 12 students from the Gymnasio do Estado (now Culto à Ciência). The students, including Pompeo de Vito, Hernani Felippo Matallo and Vicente Matallo, usually played football at Praça Carlos Gomes. Vicente Matallo became Guarani's first president. Guarani was named after maestro Antônio Carlos Gomes' opera "Il Guarany". Antônio Carlos Gomes was born in Campinas, Brazil, and is one of the most distinguished nineteenth century classical composers. Guarani was officially founded on April 1, 1911, but to avoid April Fools' Day jokes by supporters of rival teams, the directors of Guarani changed the official foundation date to April 2, 1911.

In 1949, Guarani won Campeonato Paulista Second tier, earning the right to play in the top tier the following season.

As of 2023, Guarani is one of only two Brazilian clubs not based in a state capital to have won the national championship - the other one being Santos. The club won Campeonato Brasileiro in 1978, after defeating Palmeiras.

In 1979, the club was a semi-finalist in the Copa Libertadores, but was eliminated by the eventual season champions Club Olimpia. This run remains Guarani's best performance in international competitions to date.

In 2016, Guarani qualified for the playoff semifinals of 2016 Campeonato Brasileiro Série C, thus ensuring its return to Serie B after a four-year absence.
