On 30 November 1983, Barcelona won their first Supercopa de España, beating Athletic Bilbao 3-2 on aggregate. They have since gone on to become the competition's most successful club.
It was only the second Supercopa, which pits the previous season's Copa del Rey winner against the reigning La Liga title holder. But a similar competition, the Copa Eva Duarte, was played from 1947 to 1953m which Barcelona won three times, the most for any club (no other club won it more than once).
Bilbao had won the league the previous season, including two defeats of Barcelona along the way, while Barcelona had taken the honors in the Copa del Rey over Real Madrid. The two teams met Bilbao's Estadio San Mamés on 26 October for the first leg of the Supercopa, with Barcelona claiming a 1-3 victory.
In the second leg, played before a crowd of 18,000 at the Camp Nou, Bilbao forward Endika (pictured) scored in just the 2nd minute to set the stage for a comeback, but it proved to be the only goal of the match as the two defenses held firm and Barcelona took the silverware with an aggregate score of 3-2.
Barça have since won the Supercopa an additional 11 times, most recently in 2016, to become the competion's most successful club. Bilbao, meanwhile, went on to win a league and Copa del Rey double in 1984, making them that year's automatic Supercopa champions. They returned to the Supercopa in 2015, where they beat Barcelona 5-1 on aggregate.
