History of football in Argentina (1900–1919)

In the birth of the 20th. century, the sport of association football in Argentina developed an exponential growth, with a high amount of clubs created mainly in the Buenos Aires area, plus the expansion of the sport in the city of Rosario. Among the clubs established in the 1900s were Boca Juniors, River Plate, Independiente, Racing, and San Lorenzo. which would be later known as the Big Five

The new decade was marked by the hegemony of Alumni, a club raised from the Buenos Aires English High School, which would become the most successful team of those times, being considered the first great team in the country. Despite having been dissolved in 1913, their 22 titles place Alumni as one of the most winning team in the history of Argentine football.

The large amount of titles (including the seven-consecutive Primera División titles) by Racing during the second decade of the 20th. century earned them the nickname the Academy apart of being regarded as the successor of Alumni, which had been dissolved in 1913.

The new century also brought the first breakup in Argentine football when several clubs left the official AFA to form a new league, Federación Argentina de Football, in 1912. This dissident league would run for three years until the conflict ended and both associations merged into one. Nevertheless, a new breakup would occur in 1919 when dissident clubs formed the Asociación Amateurs de Football, which organised its competitions until 1926.
