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. 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 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. ==Honours==
