Real Sociedad were founder members of La Liga in 1928. The team came fourth with Francisco “Paco” Bienzobas finishing as top scorer. The team’s name was changed to Donostia Club de Futbol in 1931 with the advent of the Second Spanish Republic, but changed back to Real Sociedad after the Spanish Civil War in 1939. The team has generally fluctuated between the Primera and Segunda divisions, in one period (during the 1940s) managing to be relegated and promoted seven times. Around that time, the sculptor Eduardo Chillida was the team’s goalkeeper until injury put a stop to his football career.
