El Salvador qualified for the FIFA World Cup twice, in 1970 and 1982. On both occasions the team was eliminated in the first round after losing all three matches.
A qualifying match against Honduras 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.[1][2][3][4]
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.
