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 three seasons while Federación Universitaria (now Club Universitario de Deportes) was the winner in 1934. 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. 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.
