From 1904 until the dawn of professional leagues in Spain, Athletic Club dominated Basque football through sheer resilience and regional pride. During these formative years, the primary competition was the Copa del Rey, where the team secured ten titles before the national league existed. This era established the club's reputation as a powerhouse capable of challenging any side on Spanish soil. The construction of San Mamés in 1913 marked a pivotal moment, giving the fans a dedicated temple to celebrate their victories. Matches at this ground became legendary events that drew thousands of supporters. The team philosophy relied heavily on local talent and physical strength, laying the groundwork for the future Basque-only policy that would define the club's identity for generations.
