Unione Sportiva Pro Vercelli Calcio was one of the most successful Italian football clubs in the early decades of the twentieth century, with seven national titles won between 1908 and 1922. Based in Vercelli, Piedmont, the team currently plays in Italy's Lega Pro Seconda Divisione.
1907 saw Pro Vercelli's football team win the Subs Division, and subsequently the club were admitted to Italian National League for the first time. Success followed quickly, with the following two years (1908 and 1909) producing the "White Shirts" first National championship titles.
Nevertheless, the Leoni ("Lions", so called for their notorious hard and not always clean tackles) did not take long to prove again their supremacy in Italian football. The following years they remain undefeated, with the unprecedented capture of three titles in a row in 1910-11, 1911-12 and 1912-13.
These years begat the legends of the famous Midfield Line of Wonders, formed by Ara, Milano I and Leone. In the same years Pro Vercelli also formed, the backbone of the first Italian national teams, with nine players representing the Piedmont club.
After such an incredible beginning, however, Pro Vercelli had to wait the end of the Great War and 1920-21 to win another National title. In the following years Pro Vercelli remained among the best Italian teams, but fell short of achieving the top prize. Other teams such as arch-rivals Casale, Genoa and Internazionale Milano overtook the "White Shirts", breaking a dominance not experienced before or since.
In 1921-22, after a row over the structure of the Italian league competition, the Italian Football Federation (FIGC) split, with all the major teams forming the independent Italian Football Confederation (C.C.I.). Pro Vercelli joined the CCI league, which had a structure with fewer matches over the year, subsequently and joyously regaining their 7th National title. Incredibly and unfortunately, it was to be their last - to date.
Pro Vercelli were invited to Rio de Janeiro to play against Flamengo and Botafogo. In the days before formalised European competition, Liverpool F.C., during a European tour as English Champions, played all the strongest team of the continent, defeating all except one: they could only manage to draw with Pro Vercelli in a clash of the finest sides in the world on the day.
