Peru Liga 1

Football was introduced in Peru in the 19th century by British residents in Lima. The early players were British residents, British sailors that stopped at the port in Callao, or upper class Peruvians were introduced to the sport on their travels. The first recorded football match in Lima was played on 7 August 1892 between British residents and Peruvians at the club ground Santa Sofía belonging to the Lima Cricket and Lawn Tennis club. Interest in sport slowly grew among the upper class Peruvians who established clubs, such as Lima Cricket & Lawn Tennis and Regatas Lima club dedicated their sporting activities to cricket and tennis, and aquatic sports. Additional clubs would follow: Lawn Tennis club, Unión Cricket, and Unión Ciclista Lima. Football would gain a following: Unión Cricket would be the inaugural club to include football in their activities. Other clubs would follow.

Just before the turn of the 20th century, football was encouraged among students that began to hold small inter-scholastic championships. The first football club in Peru was Association FBC, founded on 20 May 1897 by students from different schools. Several other schools and students started their own football clubs. One club founded on 9 June 1902 by cricket enthusiasts from the Instituto Chalaco was Atlético Chalaco. They started to play football and become a representative team of Callao. Conversely, some educational institutions, like Universidad San Marcos would adopt a system of competition among clubs formed of faculty of each its colleges. Their competitions started as early as 1899. In time one faculty team would separate from the university to form their own independent football club, known today as Universitario. Clubs unaffiliated with educational institutions started to form. One of these clubs was Sport Alianza—today Alianza Lima—which was founded by Italians and Chinese of the working class of Lima in 1901 although their available records date from around 1912.

After a period of time of random play competition among clubs, the idea of a league and championship status developed. In 1912, club Sporting Miraflores invited several other clubs in Lima and Callao to participate in the formation of a football league. Those clubs that accepted established the la Liga Peruana de Fútbol (Peruvian Football League); teams from Callao declined the invitation. The inaugural season in 1912 established two divisions; Primera División and Segunda División, both of 8 clubs. The Primera División composed of Lima Cricket, Association FBC, Miraflores Sporting, Jorge Chávez N°1, Sport Alianza, Escuela Militar de Chorrillos, Sport Inca and Sport Vitarte while the Segunda División composed Atlético Grau N°1, Atlético Peruano, Carlos Tenaud N°1, Carlos Tenaud N°2, Sport Libertad Barranco, Sport Magdalena, Sport Lima y Unión Miraflores. Lima Cricket inaugurated the tournament championship title; Association finished second.

The first edition was a relative success despite some minor setbacks. For instance, Escuela Militar de Chorrillos withdrew from the tournament in the middle of the season after only have earned 1 point. The second edition of the Liga Peruana had Jorge Chávez N°1 reach the top. The following year Lima Cricket would tally a second title. Sport José Gálvez—who refused to participate in 1912—won consecutive championships in 1915 and 1916. In 1917 Sport Juan Bielovucic championed the Liga. Sport Alianza would earn its first titles in 1918 and 1919. Sport Inca and Sport Progreso won the 1920 and 1921 seasons respectively. The league ran uninterrupted for 10 seasons until La Liga Peruana de fútbol temporarily disbanded due to disagreements. Between 1922 and 1925 no championships were played.

The Peruvian Football Federation was founded in 1922 and restarted the Peruvian football league in 1926 with the addition of teams from Callao. Unfortunately, the two championships in 1926 and 1927 suffered drawback as teams withdrew from the league mid-season. Of the 11 competing teams, Sport Progreso was crowned champion. Because many clubs withdrew from the tournament, Sport Progeso only played 6 games. The following season, Alianza Lima conquered its third title; they had already won two back-to-back titles in 1918 and 1919. This season featured 8 teams. As in 1926, the league did not finish properly and Alianza Lima won after winning its 3 matches. In 1928, the federation increased the number of teams to 19 and separated them into 2 groups. 5 teams advanced to second stage where the winner was league champion. The first Clásico took place in this season. In the second stage Alianza Lima faced the newly invited Federación Universitaria. The match was a 1–0 win for Federación Universitaria and began the biggest rivalry in the history of Peruvian football. At the end of the second stage, Federación Universitaria and Alianza Lima were tied for first place which led to two extra matches between them to declare the 1928 champion. The first match was a 1–1 draw and the second was a 2–0 win for Alianza Lima.

Following a second-place finish in their first division debut, Federación Universitaria would go on to win their first title in 1929. In 1930, the federation experimented with a new format. They separated the teams in 3 groups of 4 teams. The winner of each group advanced to the championship group to define the season champion. The three finalists were Atlético Chalaco, Alianza Lima, and Federación Universitaria. Atlético Chalaco would go on to win Callao's first title. Alianza Lima won the next four seasons. In 1935, the title would go back to Callao after Sport Boys–founded in 1927 and debuted in 1933–defeated the 4 teams it was competing against. In 1936, no championship was contested due to the participation of Peru in the Summer Olympics in Berlin. The championship returned in 1937 to be won by Sport Boys. The Peru national team that competed in Berlin was made up of mostly footballers who played in Sport Boys. One of the few exceptions was Teodoro Fernández who played for Universitario and scored 6 goals in 2 games. Deportivo Municipal, another club that would become a traditional team in Peruvian football, won its first championship in 1938 and a second in 1940 whilst Universitario a tallied four titles by winning in 1939 and 1941. Prior to 1939, teams played all other teams once in the course of the season. For the 1939, 1940, and 1941 seasons, teams played all others twice instead—a double round-robin tournament.

In 1941 the Asociación No Amateur (Non-Amateur Association) took the stand as the league's organizer and renamed the league Campeonato de Selección y Competencia. In 1942, Sport Boys won a third championship, finishing one point ahead of Deportivo Municipal. In this season, a single round-robin tournament was performed but the double round-robin returned next season. Deportivo Municipal lifted their third league trophy in 1943, and began to consolidate their place in Peruvian football. In 1944, a new champion was crowned by the name of Sucre. Universitario returned to the top after winning consecutive title between 1945 and 1946. In 1947 Atlético Chalaco won its last top flight division title. 1948 saw Alianza Lima taste glory again after trophyless seasons since their conquests between 1931 and 1933. 1949 and 1950—won by Universitario and Deportivo Municipal respectively—were the last two championships played before football would become a professional sport in Peru. Between 1946 and 1949, a triple round-robin tournament was employed until in 1950 the double round-robin system made its return. Midway through the 20th century, most of the clubs which had founded La Liga Peruana de fútbol had disappeared from the top flight and five teams had become the dominant forces in Peru; Alianza Lima, Universitario de Deportes, Deportivo Municipal, Sport Boys and Atletico Chalaco.

In 1951 the top flight of Peruvian football earned professional status and the organization of the league was handed over to the ACF or Asociación Central de Fútbol (Central Football Association). Sport Boys won the first professional championship. In the next 4 years, Alianza Lima rose to conquer 3 titles in 1952, 1954 and 1955. In addition, one-time champion Sucre won a second championship in 1953. The professional era saw the rise of a new team that would rival the five dominant clubs of the amateur era. During the course of Peruvian football, Rimac-based Sporting Tabaco was a regular contender. However, in December 1955, the brewery Backus and Johnston founded Sporting Cristal to represent them in the top flight. In their debut in professional football, Sporting Cristal won their first championship in 1956. The following season, a relatively unknown club by the name of Centro Iqueño won the championship. In addition, the 1957 season employed a new tournament format. After the double round-robin stage, the 10 teams were split into 2 groups for a further 4 matches. The top 5 would play for the season title and the bottom 5 for avoiding relegation. This format would be used until 1959, and in 1964 and 1965 (a similar format would be employed in 1969 and 1970). Sport Boys won a fifth title in 1958 while Universitario won an eighth in 1959.

The 1960 season had a new attractive feature to Peruvian football; the champion would qualify to the newly created Copa de Campeones—today Copa Libertadores. Universitario de Deportes was the first Peruvian club to compete in the South American continental tournament after winning the 1960 season. In 1962 the ACF ended its run and the ADFP took its place as the current organizer of the league. In 1965, the runner-up would join the champion in the Copa Libertadores as CONMEBOL expanded the continental tournament. Up until 1965, only clubs based in Lima or Callao competed. Therefore, in 1966 the Asociación decided to expand the league outside Lima and Callao leading the championship to be renamed the Campeonato Descentralizado (Decentralized Championship). Atlético Grau of Piura, Melgar of Arequipa, Octavio Espinosa of Ica, and Alfonso Ugarte de Chiclín of Trujillo were the first four Peruvian clubs from the country interior to be invited to play in the top flight of Peruvian football, expanding it to 14 teams. The twist in this first Descentralizado was that only the best placed club outside Lima and Callao would remain in the first division; the other three would be relegated along with 1 Lima/Callao-based team. Miguel Grau—finished sixth—remained in the first division while Universitario was crowned first Descentralizado champion. With the new national championship, the Copa Perú was created to promote clubs outside the capital hub along with the Segunda División which promoted clubs from Lima and Callao. The first Copa Perú was played in 1967—prior to the start of the 1967 Descentralizado—returning Alfonso Ugarte de Chiclín and Octavio Espinoza to the top flight in addition to newcomer Juan Aurich of Chiclayo. Universitario would go on to win the second edition of the Torneo Descentralizado. However, in this season, only one club from the country interior was relegated instead of three.

In the Torneo Descentralizado's third edition, improvements were made by the teams outside the capital hub, also known as provincianos to denote the clubs originate from the provinces of Peru. Notably Juan Aurich of Chiclayo tied with Sporting Cristal at the end of the season for first place. The championship was to be defined in a single playoff match in the Estadio Nacional. Sporting Cristal won the playoff 2–1 but Juan Aurich, as runner-up, qualified for the Copa Libertadores, being the first provinciano to do so. In 1969, the tournament suffered a minor change in the format. The tournament was played with 14 teams, as had been since 1966, however after the first leg of the round robin matchups, the table was split into two parts, with the top 6 fighting for the national title and the bottom 8 avoiding relegation. Universitario won their third Descentralizado title totalizing thirteen Primera División titles.

In 1970, the national championship would modify the previous season's format. After the clubs played each other in a double round-robin tournament, the clubs would be separated into two groups of 7 each, then playing an additional double round-robin tournament to determine the champion. Sporting Cristal finished first obtaining their fourth league title, tying Deportivo Municipal's record. For the 1971 season, the championship was expanded to 16 teams. Universitario won the season title reaching fourteen Primera División titles, tying

arch-rivals Alianza Lima in first division titles. Universitario's participation in the following season's Copa Libertadores would lead to an appearance in the continental finals against Independiente of Argentina, defeating Alianza Lima, Universidad de Chile and Unión San Felipe in the first group stage as well as defending champion Nacional and three-time champion Peñarol in the second group stage. In the first leg of the finals, they would draw in Lima 0–0 and lose 2–1 in Avellaneda. As in the 1972 Copa Libertadores, Universitario would finish second in the Descentralizado of 1972 to Sporting Cristal, tying Sport Boys 5 title record.

Starting in 1984, the regional leagues would be employed which would be a complex system which featured up to 40 teams from all over the country.

In 1997 the tournament format was modified again, this time employing a similar system being used in Argentina at the time. The general idea of the system was to divide the season into two tournaments called the Apertura and Clausura tournaments. At the end of the season the tournament winners faced in a season final for the championship title. The 1997 season did not have a final after Alianza Lima won both tournaments automatically winning the 1997 title ending an 18-season title drought. At the end of the 2008 season this format was abolished due to the lack of championship playoffs in 2007 and 2008. The 2009 season employed a new liguilla format including a regular season between 16 teams which would qualify to two groups depending on their placement at the end of the regular season. The winners of each group would dispute a two-legged final at the end of the season to determine the national champion.

In 2018 the Peruvian Football Federation announced that the league would be restructured, called "Liga de Fútbol Profesional", later changed to ''Liga 1'', and organized by the national federation itself instead of the ADFP, starting with the 2019 edition.

As of 2022, Universitario, Alianza Lima and Sporting Cristal have won 26, 26 and 20 official league titles respectively. They are regarded as the Big Three of Peru. However, other teams have risen to new heights. In particular, a team from Cusco, Cienciano, has been the only Peruvian team to win international tournaments (Copa Sudamericana 2003 and Recopa Sudamericana 2004), though it has yet to win the domestic league title. Other notable teams include Melgar, Binacional, Juan Aurich and Unión Huaral, which are the only non-capital teams to have won a national championship.
