Leganes

The club was officially founded on 23 June 1928. Its first president was Ramón del Hierro. However the club had to suspend operations in 1936 due to the Spanish civil war, where they remained inactive until they reformed on 4 September 1946.

Leganés played the vast majority of its existence in the lower leagues. In 1977 the club regained promotion to the fourth division, where it had played before for seven years when the category was still the third level.

After a steady progression, Leganés reached the new division three in 1987, being promoted to the second division six years later and maintaining its league status for 11 seasons; during this timeframe, it collected two consecutive eighth places (best) from 1995 to 1997.

On 24 December 2008, Victoria Pavón and Felipe Moreno acquired a majority stake of the club. Since July 2009, Victoria Pavón has been the president of the club.

In the 2013–14 season, Leganés was promoted to Segunda División after 10 seasons in Segunda B.

In the 2015–16 season, for the first time in their history, Leganés earned promotion to La Liga, which was sealed on 4 June 2016 with a 1–0 away win against CD Mirandés, thus becoming the fifth team from Community of Madrid ever to play in La Liga, after Real Madrid, Atlético Madrid, Rayo Vallecano and Getafe. They remained in the top flight for four seasons, reaching a peak of 13th in 2018–19, before relegation in the last game of the following season, a 2–2 home draw with Real Madrid. During this spell, the team qualified for the first time to the semifinals of the Copa del Rey, by eliminating Real Madrid in the quarterfinals thanks to a 2–1 win at Santiago Bernabéu Stadium. In 2017, Leganés planned to change their name to "Leganés Madrid" to aid putting them "on the map".

In the 2023–24 season, Leganes won Segunda Division and were promoted to La Liga, thus returning after a four-season absence. They were immediately relegated back to Segunda in the 2024-25 season.
