América de Quito

Creation and early years (1918–1954)

Liga de Quito's roots lie in a semi-pro sports team based out of the Central University of Ecuador on 23 October 1918, headed by Dr. César Jácome Moscoso. Under the leadership of Dr. Bolívar León, the club was officially founded on 11 January 1930. In the early days, Liga participated in a variety of disciplines, including football, basketball, athletics, boxing, baseball, swimming, ping-pong, and chess. The club's initial budget was about 500 sucres. The first team's players were students from the university, and had to pay for their own uniforms, medicines, and expenses. Dr. León designed the first uniform, placing its crest, a white "U" on an inverted red and blue triangle, on a white shirt, honoring the team's beginnings at the university. Amongst Liga's first players were Carlos Andrade Marín, Oswaldo Mosquera, Alfonso Cevallos, Alfonso Troya and "El Mono" Icaza.

In 1932, Liga won their first football title at an amateur Pichincha tournament; there was no national amateur league at the time. Five teams participated: Liga, Gladiador, Gimnástico, Atlético, and Cleveland. Liga won all their games, and in the final match, played at the Estadio El Ejido, defeated Gladiador by a score of 4–0. Playing for Liga were Jorge Zapater, Eduardo Flores, Alfonso Cevallos, César González, Jorge Vallarino, Jorge Naranjo, Bolívar "Ñato" León, Alejandro Dávalos, Humberto Yáñez, Humberto Freire, and Ernesto García, with Bolívar León as coach. Liga would also win amateur titles in 1952 and 1953, before the league turned professional the following year.

Beginning of professional era (1954–1966)

By 1955, the amateur football association in Pichincha had evolved into the Asociación de Fútbol No Amateur de Pichincha (Pichincha Non-Amateur Football Association), which subsequently organized a professional league for their member clubs from Quito and Ambato. The inaugural Campeonato Professional Interandino (Inter-Andean Professional Championship) was held in 1954. Liga won the league's first title, under the management of Lucho Vásquez. The club finished as the runner-up in 1955 and 1956, before winning again in 1958 under Argentine Roberto Ortega. The club won four titles during the 1960s, in 1960, 1961, 1966, and 1967, and finished as runner-up in 1962, 1963, and 1964. Liga had the most successful run of any professional Interandino-era club, accumulating a total of 6 regional titles.

In 1957 and from 1960 onwards, winning the Interandino title qualified a team to participate in a tournament which crowned a national champion of Ecuadorian professional football. Liga first participated in 1960, after winning the Interandino cup that year. The team's three subsequent Interandino victories did not lead to a national title; the club's best performance was a third-place finish in 1964.

Foreign players became integral to the squad during the 1960s. International players included Paulista José Gomes Nogueira in 1960, Chilean Román Soto in 1961, and Paraguayan José María Ocampo in 1966.

National success, relegation, and comeback (1967–1989)

In 1967, all regional tournaments were discontinued in favor of a single national tournament. Liga won its first national championship in 1969, one year after joining the new league, under the leadership of Brazilian José Gomes Nogueira. Liga's ranks at the time included Francisco "El Tano" Bertocchi, Jorge Tapia, Armando "Tito" Larrea, Carlos Ríos, Santiago Alé, Enrique Portilla, and Ramiro Tobar. Liga's victory granted the club its first Copa Libertadores participation in 1970, where it reached the second phase of the tournament, with '"El Tano" Bertocchi tying for the title of top goalscorer of the tournament.

Liga's success was short-lived; in 1972, the club finished seventh of the eight teams participating in the Serie A. At the time, only four teams from the province of Pichincha could play in the top flight. As the worst-performing Pichincha team, Liga took part in a playoff match against the best-performing Pichincha team in Serie B, Universidad Católica, for a berth in the next season's Serie A tournament. Liga lost the match, relegating it to Serie B for the 1973 season, at the end of which the club faced a second relegation, down to the Segunda Categoria of Ecuadorian football. The club was able to gain promotion back to the Serie B in time for the 1974 season. After winning the first stage of the 1974 Serie B, Liga returned to the Serie A after two years in the lower flights. Liga's rise continued as the team won their second national title after defeating El Nacional. The success was followed by another title win in 1975, marking Liga's first back-to-back national championships. Liga's 1975 and 1976 Copa Libertadores participations saw the squad twice reach the semi-finals of the continental tournament. Key to Liga's success were players Polo Carrera, Oscar Zubía, Jorge Tapia, Gustavo Tapia, Walter Maesso, Juan Carlos Gómez, Ramiro Tobar, Juan José Pérez, and Roberto Sussman, along with Colombian coach Leonel Montoya. Liga would round out the decade with a runners-up finish in 1977, allowing for another Copa Libertadores participation in 1978.
