The 1969 play-off match between El Salvador and Honduras (two teams that are not only neighbors but rivals) was filled with anticipation and aggression. This playoff match would decide which nation would be attending the world cup, and which would be staying home. El Salvador and Honduras had each won one match which forced a third, and final, play-off match.¹ In the prior matches, fights had broken out between fans in the street and in the stands during the game.  But on the day of the final play-off, a much more significant event would take place. The game was scheduled in Mexico City: a third-party country with no bias toward either team.  The day of the playoff, El Salvador dissolved all diplomatic ties with Honduras right before the match.

In the first game between the two nations, Honduras won the match 1-0 in its own capital. Some Hondurans stayed outside of the hotel that the El Salvador team had been staying at and threw rocks, set off car alarms and threw firecrackers.² The 2^nd match took place in San Salvador, where the home fans would watch their team win by a commanding score of 3-0. Before the 2nd match took place, the Honduran National team had a security force with them at all times. During the game the security at the stadium was extremely tight with lots of alcohol and weapons confiscated as a security precaution. As the Honduran national anthem played, the home team and fans were extremely disrespectful towards the players and their country. This caused some whiplash for El Salvadorians living in Honduras as their businesses were boycotted and vandalized.³ Leading up to the  series of matches, the two nations were in a deep dispute over land reform and immigration. El Salvador was sending its poorest citizens into Honduras so the wealthy could maintain their land.⁴ El Salvador had a much bigger population than Honduras. Honduras had a population of about 2 million, where as El Salvador had a population of almost 4 million.⁵

However, they had a significantly smaller amount of land which forced more than 275,000 El Salvadorians to flee into Honduras, causing poverty and crime.⁶ Honduras accused the El Salvadorians of stealing jobs from the native people of Honduras. But after the 2^nd games violence, El Salvador accused Honduras of staying silent while El Salvadorians living in Honduras were raped, murdered, robbed, and oppressed. Neither side was willing to negotiate to the smallest extent, which led to tensions building up even more. In the final match between the two teams, El Salvador won the game in overtime with the score of three to two.⁷ This caused numerous Salvadorians to be killed in Honduras.⁸

On July 14^th, 1969, almost 3 weeks after the final playoff game, El Salvador bombed targets inside of Honduras. They crippled Honduras by attacking their main airport which left them unable to react to the attack at optimal speed.⁹ El Salvador then attacked from the ground by marching through the two main roads that connect the countries. Only one day later, the El Salvadorian army had pushed Honduras back over 8 kilometers. The El Salvadorian Army continued to make steady progress. They were nearing the capital city of Honduras, Tegucigalpa, when Honduras finally pushed back.  The Honduran Air Force attacked Llopango base. The bombers eventually progressed to Acajutla port, which was important because it was home to El Salvadorian oil refineries. Later that evening huge smoke clouds covered the coast as the the oil refineries were bombed.¹⁰

Fearing that the nearing El Salvadorian army would overtake the capital, Honduras called the Organization of American States for help. The Organization of American States (OAS) had an urgent meeting on the evening of July 15^th and called for El Salvador to withdraw its troops from Honduras ensuring that its people living in Honduras would not be harmed.¹¹ El Salvador refused, demanding reparations be paid to them and their citizens. El Salvador attempted to further the attack the capital city, but they were unable to proceed with the attack. The previous strike on their oil refineries had destroyed their line of fuels and supplies and they no longer had supplies arriving every other day.  Somoza Debayle, the dictator of Nicaragua was also helping Hondurans by arming them with weapons and providing ammunition. The OAS worked night and day in order to provide a cease-fire that would please both parties. Finally, on the night of July 18^th, a ceasefire was arranged and became effective two days later.¹²

Although the cease-fire had been called, El Salvador refused to leave Honduras. They stayed until they were threatened by the OAS with economic sanctions against them. The El Salvador government finally withdrew troops on August 2, 1969. The aftermath of the 100-hour war was anything but slim. More than 2000 civilians were killed, with more than 100,000 immigrants displaced.¹³ Although they were no longer at war with each other, these two nations peace treaty only came into force on December 10, 1980.¹⁴
