Football War The Football War ( Spanish : La guerra del fútbol ) , also known as the Soccer War or 100 Hour War , was a brief war fought by El Salvador and Honduras in 1969 . The cause of the war was economic in nature , namely issues concerning immigration from El Salvador to Honduras . These existing tensions between the two countries coincided with rioting during the second North American qualifying round of the 1970 FIFA World Cup . The war began on 14 July 1969 , when the Salvadoran military launched an attack against Honduras . The Organization of American States negotiated a cease - fire on the night of 18 July ( hence " 100 - hour War " ) , which took full effect on 20 July . Salvadoran troops were withdrawn in early August . Eleven years later the two nations signed a peace treaty on 30 October 1980 and agreed to resolve the border dispute over the Gulf of Fonseca and five sections of land boundary through the International Court of Justice . In 1992 , the Court awarded most of the disputed territory to Honduras , and in 1998 , Honduras and El Salvador signed a border demarcation treaty to implement the terms of the ICJ decree . The total land area given to Honduras from El Salvador after the court ' s ruling was around . As of the beginning of 2006 demarcation had not yet been completed , but Honduras and El Salvador maintain normal diplomatic and trade relations . Context . Although the nickname " Football War " implies that the conflict was due to a football game , the causes of the war go much deeper . The roots of the war were issues over land reform in Honduras and immigration and demographic problems in El Salvador . Honduras is more than five times the size of neighbouring El Salvador , but in 1969 El Salvador had a population that was more than double that of Honduras . At the beginning of the twentieth century , Salvadorans had begun migrating to Honduras in large numbers . By 1969 , more than 300 , 000 Salvadorans were living in Honduras . These Salvadorans made up twenty percent of the peasant population of Honduras . In Honduras , as in much of Central America , a large majority of the land was owned by large landowners or big corporations . The United Fruit Company owned ten percent of the land , making it hard for the average landowners to compete . In 1966 , the United Fruit Company banded together with many other large companies to create la Federación Nacional de Agricultores y Ganaderos de Honduras ( FENAGH ; the National Federation of Farmers and Livestock - Farmers of Honduras ) . FENAGH was anti - campesino as well as anti - Salvadoran . This group put pressure on the Honduran president , General Oswaldo López Arellano , to protect the property rights of wealthy landowners . In 1962 , Honduras successfully enacted a new land reform law . Fully enforced by 1967 , this law gave the central government and municipalities much of the land occupied illegally by Salvadoran immigrants and redistributed it to native - born Honduran peoples as specified by the Land Reform Law . The land was taken from both immigrant farmers and squatters regardless of their claims to ownership or immigration status . This created problems for Salvadorans and Hondurans who were married . Thousands of Salvadoran laborers were expelled from Honduras , including both migrant workers and longer - term settlers . This general rise in tensions ultimately led to a military conflict . Buildup . Honduras and El Salvador met in the second North American qualifying round for the 1970 FIFA World Cup . There was fighting between fans at the first game in the Honduran capital of Tegucigalpa on 8 June 1969 , which Honduras won 1 – 0 . The second game , on 15 June 1969 in the Salvadoran capital of San Salvador , which was won 3 – 0 by El Salvador , was followed by even greater violence . A play - off match took place in Mexico City on 26 June 1969 . El Salvador won the decisive third game 3 – 2 after extra time . That same day , El Salvador dissolved all diplomatic ties with Honduras , stating that " the government of Honduras has not taken any effective measures to punish these crimes which constitute genocide , nor has it given assurances of indemnification or reparations for the damages caused to Salvadorans " . War . Late in the afternoon of 14 July 1969 , concerted military action began . San Salvador City was put on a black out and the Salvadoran Air Force , using passenger airplanes with explosives strapped to their sides as bombers , attacked targets inside Honduras . The better equipped Honduran air force was caught off guard by the Salvadoran aggression . Salvadoran air - raid targets included the airport facility at Toncontin , which left the Honduran Air Force unable to react quickly . The larger Salvadoran army , launched major offensives along the two main roads connecting the two nations and invaded Honduras . Initially , rapid progress was made by the Salvadoran army , by the evening of 15 July , the Honduran army had been pushed back over eight kilometers . The departmental capital of Nueva Ocotepeque fell shortly after along with eight other cities , placing the Salvadoran army within striking distance of the Honduran capital Tegucigalpa . The momentum of the advance did not last , however . The Honduran air force reacted by striking the Salvadoran Ilopango airbase . The effectiveness of the attack on Ilopango has been called into question , however it is generally accepted that the bombing of oil facilities and depots severely disrupted the logistics of the Salvadoran army . There is enough evidence to support the contention that , after the surprise Salvadoran air - raid attacks on Toncontin , the Honduran air force did manage to establish and maintain control of the air in their territory . On 15 July , the Organization of American States met in an emergency session and demanded that El Salvador withdraw from Honduras . The government in San Salvador refused unless promised that reparations would be made to those Salvadorans who were displaced and those who remained in Honduras would not be harmed . During the war , the Third Military Zone of the Honduran Army was discovered to have only half of its allotted soldiers . The money for the missing troops had been collected by an apparently corrupt Honduran Army officer . Nicaraguan dictator Anastasio Somoza Debayle helped Honduras by providing weapons and ammunition . Cease fire . The Honduran government called on the OAS to intervene , fearing that the nearing Salvadoran Army would invade the capital Tegucigalpa , the OAS met in an urgent session and called for an immediate cease - fire and a withdrawal of El Salvador ' s forces from Honduras . El Salvador resisted the pressures from the OAS for several days , demanding that Honduras first agree to pay reparations for the attacks on Salvadoran citizens and guarantee the safety of those Salvadorans remaining in Honduras . A cease - fire was arranged on the night of 18 July ; it took full effect only on 20 July . El Salvador continued until 29 July to resist pressures to withdraw its troops . Then a combination of pressures led El Salvador to agree to a withdrawal in the first days of August . Those persuasive pressures included the possibility of OAS economic sanctions against El Salvador and the dispatch of OAS observers to Honduras to oversee the security of Salvadorans remaining in that country . The actual war had lasted just over four days , but it would take more than a decade to arrive at a final peace settlement . Withdrawal . El Salvador finally withdrew its troops on 2 August 1969 . On that date , Honduras guaranteed Salvadoran President Fidel Sanchez Hernandez that the Honduran government would provide adequate safety for the Salvadorans still living in Honduras . He had also asked that reparations be paid to the Salvadoran citizens as well , but that was never accepted by Hondurans . There were also heavy pressures from the OAS and the debilitating repercussions that would take place if El Salvador continued to resist a withdraw of their troops from Honduras . The war in the Central American skies over El Salvador and Honduras is said to be the last conflict in which piston - engined fighters fought each other , both sides deploying World War II era aircraft . Cavalier P - 51D Mustangs , F4U - 1 , - 4 and - 5 Corsairs , T - 28A Trojans , AT - 6C Texans and even C - 47 Skytrains converted into bombers saw action . Consequences . Both sides of the Football War suffered extensive casualties . Some 300 , 000 Salvadorans were displaced due to the battle . Many had been forcibly exiled or had fled from war - torn Honduras , only to enter an El Salvador in which the government was not welcoming . Most of these refugees were forced to provide for themselves with very little assistance . Over the next few years , more Salvadorans returned to their native land , where they were surrounded by overpopulation and extreme poverty . El Salvador suffered about 900 casualties , troops and civilians , killed during the war . Honduras lost 100 combat troops , and over 2 , 000 civilians during the four - day war . Most of the war was fought on Honduran soil and thousands more were made homeless . Trade between Honduras and El Salvador had been greatly disrupted , and the border officially closed . This damaged the economies of these nations tremendously and threatened the Central American Common Market ( CACM ) .
