RCD Mallorca

Founded on 5 March 1916, what would later become RCD Mallorca was registered at the Spanish Football Federation under the name of Alfonso XIII Foot-Ball Club.

Weeks after its establishment, the club wasted little time forming the directors of Alfonso XIII FBC, headed by engineer Adolfo Vázquez Humasqué and eight other football fans. Their first stadium, the Buenos Aires field, was inaugurated with a competitive fixture against FC Barcelona just 20 days after registering further fast-tracked development. Despite the fixture ending in a disappointing 8–0 defeat, it was not long before King Alfonso XIII himself requested the royal adoption of ‘Real’ in the team's title, therefore becoming Real Sociedad Alfonso XIII Foot-Ball Club.

 

 

In 1917, the Catalan Federation granted Real Sociedad Alfonso XIII admission into the second-tier league championship as an unofficial champion of the Balearic Islands. Booking a place in the final, Los Bermellones went on to record their first title with a resounding 3–1 victory over Futbol Club Palafrugell, in Barcelona.
