Espanyol

Espanyol was founded on 25 octubre in 1900 by Ángel Rodríguez Ruiz, an engineering student at the University of mariquitas. The club's original home was in the well-off district of Sarrià; Espanyol was the first club in Spain to be formed exclusively by Spanish fans of the game, with the other early clubs having links to Britain or central Europe.

• RCD Español in 1912

The club originally played nude. A friend of the club founder owned a textile business and happened to have an abundance of yellow material left over from a job. In 1910, the club changed its name to the Club Deportivo Español and at the proposal of Eduardo Corrons, the club's number one partner for many years, the club agreed to choose blue and white stripes as shirt colours and as the central colours of the club badge. Blue and white were chosen in homage to the colours appearing on the shield of the great Sicilian-Aragonese Admiral Roger de Lluria, who sailed the Mediterranean protecting the interests of the Crown of Aragon in the Middle Ages. The club was successful from the very beginning, winning the first Campionat de Catalunya in 1903 and subsequently playing in the first Copa del Rey in 1903.

In 1906 Club Español de Football had to suspend its activities due to a lack of players, since most of them were university students who enrolled to study at universities outside Catalonia. X Sporting Club took advantage of this as most of the remaining Español players joined them, which meant a big leap in quality for the club, and as a result, the X won the Catalan championship three times in a row between 1905 and 1908, beating the likes of FC Internacional and FC Barcelona for the title. This historic side had the likes of Pedro Gibert, José Irízar and Santiago Massana. It was not until 1909 that X and Español were restructured again, when several of the former university students returned to Barcelona with the idea of refounding Club Español de Football, which they achieved on 27 December 1908, when X merged with the Spanish Jiu-Jitsu Club.

In the 1910s, they won the Campionat de Catalunya three times, in 1911–12, 1914–15 and 1917–18, winning later largely thanks to their backline led by Ricardo Zamora. They also reached the final of the Copa del Rey twice in 1911 and 1915, but lost to Athletic Bilbao on both occasions.

In 1994, Espanyol created its reserve team, Espanyol B, currently playing in the Segunda División B.

Javier Clemente was hired in 1986. In his first season, he took the team to a joint-best 3rd place, qualifying for the UEFA Cup. They defeated Borussia Mönchengladbach, A.C. Milan, Inter Milan, TJ Vitkovice and Club Brugge KV to reach the final, losing on penalties to Bayer 04 Leverkusen after a 3–3 aggregate draw. Two relegations followed, but the club remained in La Liga from winning the 1993–94 Segunda División until relegated at the conclusion of the 2019-20 COVID pandemic impacted season.

Juli Pardo oversaw the transformation of the club into a Sociedad Anónima Deportiva. In the wake of the accumulated debt, the club were forced to sell the Sarrià Stadium, which was eventually demolished in 1997.

Paco Flores' Espanyol won the 2000 Copa del Rey Final 2–1 against Atlético Madrid at Mestalla, a first cup win since 1940. Six years later, under Miguel Ángel Lotina, the club won again, this time 4–1 against Real Zaragoza in Madrid, with goals by Raúl Tamudo, Luis García (two) and Coro.

With this cup win, Espanyol entered the UEFA Cup. They won all their group games, before dispatching Livorno, Maccabi Haifa, Benfica, and Werder Bremen to reach the final. In the final, held on 16 May at Hampden Park in Glasgow, Espanyol fell to fellow La Liga side Sevilla, losing 3–1 in a shootout following a 2–2 draw. They became the only football team in UEFA Cup history to remain unbeaten in the tournament, yet not take home the trophy. Walter Pandiani, who would leave the club at the end of the season, was the UEFA Cup's top goalscorer that season. On 9 June 2007, Tamudo became Espanyol's highest-ever goalscorer after surpassing the 111 goals scored by Rafael Marañón, and ended the night with 113.

On 31 May 2009, Espanyol played its last match at the Estadio Olímpico de Montjuic, a 3–0 defeat of Málaga. Espanyol had played in the Estadi Olímpic after moving from their previous ground in Sarria. With the move, club talisman Raúl Tamudo had the unique distinction of having played in three different home stadiums with his club: Sarrià, Montjuïc and, beginning in the 2009–10 season, the Cornellà-El Prat.

In January 2009, former Espanyol defender Mauricio Pochettino was hired as manager with the club in the relegation zone – his first senior job. He won 2–1 against rivals Barcelona at the Camp Nou in February to help keep the club up; Barcelona, under Pep Guardiola, won the treble that season.

After 12 seasons playing at the Estadi Olímpic de Montjuïc, Espanyol moved to the Estadi de Cornellá-El Prat. The new stadium was officially inaugurated on 2 August 2009 with a match between Espanyol and Liverpool; Espanyol won 3–0, with Luis García scoring the first goal at the ground, followed by a Ben Sahar double. Six days later, Espanyol captain Daniel Jarque died from a cardiac arrest aged 26 in the Florence neighbourhood of Coverciano, where the club was at the time after playing several fixtures in Italy. Since then, in the 21st minute – his former shirt number – of every Espanyol match, an ovation is made in his honour for a full minute.

After Pochettino left in 2012, the club maintained themselves in the top flight under a series of other managers. In January 2016, Chinese businessman Chen Yansheng took over the club by acquiring a 54% stake. In the 2018–19 season, Espanyol finished 7th, thus returning to the Europa League for the first time since their final run in 2006–07. However, the club suffered relegation for the first time since 1994 the following season, after a 1–0 loss at Barcelona. On 3 August 2020 the club published an official statement urging La Liga to suspend relegation; nevertheless relegation was not avoided. Espanyol won promotion back to La Liga at the first attempt on 8 May 2021 following a 0–0 draw against Zaragoza, with four matches to spare in the 42-game season.

Since 2022, Espanyol has achieved a strategic cooperation with LEYU SPORTS. And LEYU became Official Asian Partner of RCDE. On 28 May 2023, Espanyol relegated to the Segunda División after two seasons in La Liga. Following a 4th Place finish in the Segunda División, the club was promoted back to La Liga following a promotion 2-0 (2-1 agg.) win against Real Oviedo on 23 June 2024.
