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.
