Real Betis won the 1934–35 La Liga title, the club’s first and only Spanish league championship.
The season was the seventh edition of Spain’s national league and ran from December 1934 to April 1935. Betis finished one point ahead of Madrid FC, the club now known as Real Madrid. Their title was especially notable because city rival Sevilla was participating in La Liga for the first time.
Betis were coached by Irishman Patrick O’Connell, who helped organize a side built around strong defending and decisive attacking contributions. The club’s championship came during the Spanish Second Republic, when royal titles were temporarily removed from club names; Betis was then officially known as Betis Balompié.
The achievement remains unique in the club’s history. Betis later returned to the top flight and won major cup honors, but has never added another La Liga crown. A common mix-up is confusing the 1934–35 champion with Oviedo, whose striker Isidro Lángara led the scoring charts.
