Leeds United first played European football with their appearance in the 1965–66 Inter-Cities Fairs Cup, a competition which they have won twice.
They had been on the losing side in the same competition a year previously, and won it again in 1970–71, the final season of its existence before it was effectively replaced by the new UEFA Cup.
League title glory in 1992 sealed their return to Europe after more than a decade as England's representatives in the European Cup, where they were eliminated in the second round by Scottish champions Rangers.
In 1999–2000, the club enjoyed its best run in European competitions for 25 years, reaching the semi-finals of the UEFA Cup.
By this stage, however, the club was deep in financial trouble and was starting to sell most of its key players, which contributed to relegation from the Premier League at the end of the 2003–04.
