El Salvador qualified for the FIFA World Cup twice in their history, in 1970 and 1982. On both occasions the team were eliminated in the first round after losing all three matches.
A qualifying match against the Honduran national team for the 1970 tournament was so hotly contested that it was the spark that brought a state of war between El Salvador and Honduras. The conflict became known as the Football War.
The 1982 tournament included a 10-1 mauling from Hungary that provided the most goals in a game in the history of the finals as well as equalling the record for winning margin.
