Founded in 1923 as the result of a merger between all of the town's clubs, Elche entered the league system in 1929, reaching Segunda División in 1934 and La Liga in 1959, finishing fifth in the latter tournament in 1963–64. The club were runners-up in the Copa del Rey in 1969. Elche became the first and only club in the history of La Liga to be relegated due to unpaid tax debts in the 2014–15 season. Elche returned to La Liga in 2020–21 after being promoted to the Segunda División and then La Liga in only three seasons.
Elche Club de Fútbol was founded in the summer of 1923, after the merger of all of the town's football teams. The club's first-ever game was against Monóvar, where they beat the home team 4–0, and its first official match was a 2–0 win over Crevillente. In its first years Elche, like many teams of the time, played in an all white uniform. The team played its first league season in 1929–30, in the Tercera División, achieving promotion to the Segunda División in 1934. However, Elche suffered relegation for the first time six years later, but were promoted back the following season.
In the late 1950s, Elche achieved two consecutive promotions from the third level to La Liga, securing the club's first promotion to the latter competition with a 3–0 success against Tenerife in 1959.
