sides– and the Cup Tie Competition, contested by winners of "Copa de Competencia" in both countries. Boca Juniors also participated in the Copa Escobar-Gerona (created when Conmebol already existed), winning two titles. Conmebol has mentioned those competitions as "the first official and international matches between clubs in South America". The South American Football Confederation (CONMEBOL) has organized different competitions at club level throughout history. The first competition organized by Conmebol was the South American Championship of Champions in 1948, at the initiative of the Colo-Colo club, which had the idea of organizing a tournament with the champions of each of the local leagues in South America, and the winner was designated as the South American champion. After this contest, the dispute of the official international championships was interrupted until 1960, when the South American teams began to participate in the Copa de Campeones de América, which adopted the name of Copa Libertadores de América in 1965. At the beginning, only the league champions participated, but with the passing of the editions, the number of participating teams has expanded. Due to this, the Argentine Soccer Association (AFA) has developed different classification methods for Conmebol tournaments. The formats were varying on the different occasions in which they were implemented, in addition to having different amounts of places to participate in the maximum international tournament. Over the years, many competitions were implemented, of which most were discontinued. The FIFA competitions are the Intercontinental Cup/FIFA Club World Cup, to which can only qualify by virtue of winning the Copa Libertadores. Copa Aldao The Copa Aldao was a AFA/AUF club competition contested annually, albeit irregularly, between the league champions of Argentina and Uruguay. The cup is one of several inter-South American club competitions that have been organised on the continent. The first competition was scheduled for the 1913 season (although it was never played) and the last in 1955 (actually played in 1959, no champions proclaimed). The Copa Ricardo Aldao is seen today as the first stepping-stone into the creation of Copa Libertadores. Boca played in 1919, 1920, and 1940, but could never win the title. Tie Cup The Tie Cup was a football tournament played between representatives of the Argentina and Uruguay Associations. It was one of the earliest international football tournaments played between members of different national football associations, played on an annual basis until 1919. The competition was inspired by English FA
