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.
La Liga
In April 1927, José María Acha, a director at Arenas Club de Getxo, first proposed the idea of a national league in Spain. After much debate about the size of the league and who would take part, the Real Federación Española de Fútbol eventually agreed on the ten teams who would form the first "Primera División" in 1929. Barcelona, Real Madrid, Athletic Bilbao, Real Sociedad, Arenas Club de Getxo and Real Unión were all selected as previous winners of the Copa del Rey. Atlético Madrid, Espanyol and Europa qualified as Copa del Rey runners-up and Racing de Santander qualified through a knockout competition. Only three of the founding clubs, Real Madrid, Barcelona and Athletic Bilbao, have never been relegated from the "Primera División".
