1911 Copa del Rey

This complaint was unsuccessful, but ended up causing incidents, angry protests from other teams and the withdrawal of several of them; which prevented a normal development of the tournament.

To put an end to the schism of the previous edition (which led to the celebration of two championships), the Spanish Federation accepted to hold the tournament in Vizcaya for the first time.

After the remaining teams, except the military academies, supported Real Sociedad and most of them threatened to also withdraw, Athletic decided not to use these players in their matches, but declined Fortuna Vigo's request to replay their match, which caused a general discomfort in the rest of the contenders and a feeling of comparative grievance that degenerated into more incidents and withdrawals.
