Formed in 1940 by the merger of Deportivo Gallo and Union Deportiva Eibarresa, the club was originally known as Eibar Futbol Club before changing its name to Sociedad Deportiva Eibar. Promoted to La Tercera in 1950, the Basques reached La Segunda five years later. However, after a five-year stint they suffered relegation and spent all but three of the following 28 years in the third tier of Spanish football.
Eibar returned to the ‘silver category’ in 1988, yet much of the time since then has been spent alternating between La Segunda and Segunda B. Nonetheless, back-to-back promotions ensured top-flight football at Ipurua for the first time following a 1-0 home win over Deportivo Alaves in May 2014.
At the same time, the club was threatened with relegation due to its inability to convert to a public limited company, as required by law, but two months later announced it had reached the established goal of necessary share capital.
Los Armeros (The Gunners), as Eibar are known, had perhaps their finest moment in the 2012-13 edition of the Copa del Rey when they knocked out neighbours Athletic Bilbao on the away goals rule before falling to Malaga in the last 16.
