On 15 December 1907, Porto played its first match against a foreign team, hosting Spain's Real Fortuna. In the following month, Porto returned the visit and played its first match abroad. Four years later, the club won the inaugural staging of the Taça José Monteiro da Costa, securing its first-ever major title. In 1912, Porto joined efforts with Leixões to establish the Porto Football Association, which began organising the regional championship in the following year. Porto finished the first season as runners-up, behind local rivals Boavista, but in the following season the club won its first championship. By the end of the 1920–21 season, Porto had been regional champions six times in seven years, and outright winners of the Taça José Monteiro da Costa, after claiming a third consecutive victory in 1916.
