Chilean Primera División
[citation needed] The first edition of professional competition was contested by the eight founding teams and was won by Magallanes after defeating Colo-Colo in a decisive match.
As part of the negotiations for reunification, four teams from AFS, namely, Ferroviarios, Carlos Walker, Deportivo Alemán, and Santiago F.C., would join the 1934 professional competition.
In the 1940 championship, the traditional two-wheel system was restored and Universidad de Chile had a great squad under the leadership of Luis Tirado and with players such as Víctor Alonso, the tournament's top scorer with 20 goals, Abanés Passalacqua and goalkeeper Eduardo Simián, and was crowned professional champion for the first time after only three years in the top division.
In the 1948 tournament, historic Italian players such as goalkeeper Daniel Chirinos, defender Carlos Varela and strikers Juan Zárate and Domingo Romo once again led Audax Italiano to its third professional title.
In the 1961 tournament, Universidad de Chile and Universidad Católica tied in points and forced two final matches in which, after a draw in the first leg, the Cruzados team won the return leg by 3-2, with a penalty kick by Alberto Fouillioux at 85 minutes, a score that led it to obtain its third national title.
The arrival of the 1970s saw Colo-Colo, in the national championship, obtain its tenth star after seven years, by beating Unión Española in a close final, counting on great figures such as Francisco Valdés, Carlos Caszely, Leonel Sánchez (who arrived as a reinforcement for Colo-Colo that year), Humberto Cruz, Juan Carlos Gangas, Víctor Zelada, the Uruguayan José María Piriz and the Brazilian Elson Beyruth.
In 1971, the tournament returned to the round-robin system, with the Unión San Felipe team, coached by Luis Santibáñez, winning the championship.
At the bottom of the table, Colo-Colo had to play a match to stay in the top flight for the first time in its history, which it managed to overcome after beating Universidad de Concepción 1-0, with a goal from Argentine Pablo Solari, in a duel that was played on February 17, 2021, at the Estadio Fiscal de Talca.
The 2024 tournament is considered by fans and analysts as the best of the long tournaments, after a fierce fight between Colo Colo and Universidad de Chile (the first between the two since 1998) obtaining almost 20 points over the third place, which was the surprising Deportes Iquique of Miguel Ramírez (who was returning to the top flight and who snatched Chile 3 for the 2025 Copa Libertadores from Universidad Católica, which occurred on Saturday of the Telethon).
The Cruzados team led by Brazilian Tiago Nunes and who lost at home 2-1 to Coquimbo Unido, had to settle for securing their ticket to the 2025 Copa Sudamericana.
The title finally fell to the side of the white team, led by the Argentine Jorge Almirón, after tying 1-1 on the last date as a visitor against the relegated Deportes Copiapó and given that the blue team led by his compatriot Gustavo Álvarez, could not win their home game against Everton, tying by the same score, which would have forced a final match.
Currently, the two teams that place bottom in the season, are relegated to Primera B de Chile, and replaced by the champions and the playoff winners of this division.
