Founded in 1923 under the name of Imperio Foot-Ball Club, the club changed its name to Imperio Club de Fútbol in 1940 due to the new language rules in all country.
After the Spanish Civil War ended in 1939, the Imperio CF reorganized and created a new board with the aim of competing in the Castilla Championship. The team's greatest achievement was competing in Spain's Segunda División for one season in 1939–40 season, under coach José Quirante, and with the likes of Ramón Colón, Antonio Muñoz, and Cuestita, which ended in relegation.[1] Imperio's members, aware of the delicate nature of the moment and in need of financial aid, know how to move quickly and skillfully, establishing contacts with the recently merged Athletic-Aviación Club, the future Atlético Madrid.[2] Seeing the potential resources that this club has, Ángel Lehoz, Luis Mesa, Ventura Miguel, and Gregorio Lázaro arrange a meeting with the Atlético's Manuel Gallego, and Juan Touzón, and Imperio FC is declared a colchonero subsidiary with Ángel Lehoz as president.[2]
