19 April 1925 - Colo-Colo Heats Up In Chile

On 19 April 1925, a group of former Magallanes players formed a new club. Named Colo-Colo, it has since become Chile's most successful club, with a record 29 Primera Division titles.

The splinter group, led by Chilean international striker David Arellano (pictured), left Magallanes after failing to persuade their former club to take professional status. The chose the name of a famous chief from the local Mapuche tribe, who is also represented on the club's badge.

They won their first regional title in their first season, then won two more in 1928 and 1929. Unfortunately, David Arellano did not see the latter two, as he sustained an injury during a 1927 friendly against Spanish club Real Valladolid. He contracted peritonitis and died the following day. In his memory, Colo-Colo added a black line over the badge.

Chile established the Primera Division in 1932 and Colo-Colo won it for their first time in 1937. Since then, they've won it a record total of 29 times, almost double the next-highest tally (Universidad de Chile have the second most with 15).

Colo-Colo have also enjoyed success on the international stage, winning the Copa Libertadores and Copa Interamericana in 1991, as well as the 1992 Recopa Sudamericana.

6 June 1973 - No Copa For Colo-Colo

On 6 June 1973, Independiente won their fourth Copa Libertadores, beating Colo-Colo after extra time in a replay.

The most successful club in the competition's history, Independiente won their first tournament titles in 1963 and 1964, then won it again in 1972. As defending champions, they entered the 1973 edition in the semifinal group stage, where they advanced over San Lorenzo and Millonarios.

Colo-Colo, meanwhile, topped their opening-round group that included Uníon Española, Emelec, and El Nacional, then advanced to their first final by winning their semifinal group over Botofogo and Cerra Porteños.

Scheduled to be played over two legs, the Final opened on 22 May in Buenos Aires, where the two teams played to a 1-1 draw. One week later in Santiago, they drew again, 0-0, to force a replay at a neutral ground. They met on 6 June in Montevideo and again found little to separate them. They were even at 1-1 at the end of regulation before Indepentiente eventually found an extra-time winner.

Independiente returned to the Final three more times (1974, 1975, 1984) and currently hold a tournament-record seven titles. Colo-Colo eventually got a title of their own, winning it in 1991 on their only other trip to the Final.
