In 1904, Abalo and his group of friends formed a football team called Coruna. The game reached a new popularity as members of a prestigious gymnasium called Sala Calvet took notice and began to practice this new sport considered "exotic" by the young people of the city. This was the start of football's passage of time in Coruña.

In 1902 the two Bilbao clubs formed a combined team, known as Club Vizcaya, in the first Copa del Rey. They returned with the trophy after defeating FC Barcelona in the final. This would lead to the eventual merger of the two clubs as Athletic Club de Bilbao in 1903. In the same year Basque students also formed Athletic Club de Madrid. This club later evolved into Atlético Madrid. The club itself declares 1898, but others claim 1901 is the true founding year.

The Club was founded on 9 October 1939. A previous club was originally founded on 26 April 1903 as Athletic Club de Madrid by three Basque students living in Madrid. The founders saw the new club as a branch of Athletic Bilbao. In 1904 they were joined by dissident members of Real Madrid. They began playing in blue and white, as did Athletic Bilbao, but by 1911 they were playing in their current colours. The reason the club changed colours is not known for certain.

On 6 March 1902, after a new Board presided by Juan Padrós had been elected, Madrid Football Club was officially founded. On 18 April, the Club Regulations, comprised of 22 articles divided into three headlines, were presented to the authorities. On 22 April 1902, José Sánchez-Guerra, Civil Governor of the Province approved the document.

On 22 October, 1899, Joan Gamper placed an advert in Los Deportes declaring his wish to form a football club. A positive response resulted in a meeting at the Gimnasio Solé on November 29. Eleven players attended, Walter Wild, Lluís d'Ossó, Bartomeu Terradas, Otto Kunzle, Otto Maier, Enric Ducal, Pere Cabot, Carles Pujol, Josep Llobet, John Parsons and William Parsons. As a result Foot-Ball Club Barcelona was born.
