In 1903, Santiago formed its own football association. This association had antecedents in the neighbors of Cousino Park (current O'Higgins Park) and some Santiago College students, led by a professor, Mister Vincent, who put on a demonstration at Mars Field, which allowed the club to begin to attract more participants. On 16 October 1903, the club was formed thanks to the management of the students the club was founded as Santiago Football Club. The team played its first match against the teacher's team, three days later on 19 October. In 1928, the club won the amateur league (Liga Central de Football).
