Salvadoran football began in the city of Santa Ana, on a field known as "Campo Marte." This was the first time El Salvador hosted a football game. On July 26, 1899, players from Santa Ana and San Salvador competed in the inaugural game. The visitors won 1-0. Two years later, in 1900, the national federation was founded with representatives from all over El Salvador. They held their first official tournament that same year. Santa Ana's team was named "Rojos" or "Red Rovers" after its color. They defeated Alba 4-1 in the final. Football became popular throughout El Salvador. There were many clubs who played against each other for prestige and money. The most famous match was probably the final of the first national championship which took place in Santa Ana on November 12, 1901. Racing Club beat Alba 5-4 in front of 10,000 people. This is when they invented the "clásico" or classic between two teams from San Salvador: Olimpia and Vista Alegre. These games were very important at the time because the winners would play in the final match of the season against another club from San Salvador for the title. The number of spectators at football matches increased every year. This made it difficult for fans to get in so police started allowing groups of ten people into the stadium.
