History of Athletic Bilbao
Meanwhile, sons of the Basque educated classes had made the opposite journey and went to Britain to complete their studies in civil engineering and commerce. While in the United Kingdom, these students developed an interest in football and on their return to Bilbao they began to arrange games with British workers. In 1898, students belonging to the Gymnasium Zamacois founded the "Athletic Club", using the English spelling. In 1901, a meeting was held in the Café García, which established more formal rules and regulations. In 1902, the two Bilbao clubs formed a combined team, known as "Bizcaya", in the first Copa del Rey. They returned with the trophy after defeating Barcelona in the final. This would lead to the eventual merger of the two clubs as "Athletic Club" in 1903. In the same year, Basque students also formed "Athletic Club Madrid"; this club later evolved into Atlético Madrid. The club's foundation date is a subject of debate among football historians. The club itself declares 1898, but others claim 1901 or 1903 as the true founding year.
Atlético Madrid
By 1939, when La Liga had resumed, Athletic had merged with "Aviación Nacional" of Zaragoza to become "Athletic Aviación de Madrid". Aviación Nacional had been founded in 1939 by members of the Spanish Air Force. They had been promised a place in the Primera División for the 1939–40 season, only to be denied by the RFEF. As a compromise, this club merged with Athletic, whose squad had lost eight players during the Civil War. The team were awarded a place in the 1939–40 La Liga campaign only as a replacement for Real Oviedo. With the legendary Ricardo Zamora as manager, the club subsequently won their first La Liga title that season and retained the title in 1941. The most influential and charismatic player of these years was the captain Germán Gómez, who was signed from Racing de Santander in 1939. He played eight consecutive seasons for the "Rojiblancos" until the 1947–48 campaign. From his central midfield position, he formed a legendary midfield alongside Machín and Ramón Gabilondo.
In 1941, a decree issued by Francisco Franco banned teams from using foreign names and the club became "Atlético Aviacion de Madrid". In 1947, the club decided to drop the military association from its name and settled on its current name of "Club Atlético de Madrid". The same year saw Atlético beat Real Madrid 5–0 at the "Metropolitano", their biggest win over their cross-town rivals to date.
