We compete in the EFL Championship, the second tier of English football. Founded as Millwall Rovers in 1885, the club has retained its name despite having last played in the Millwall area of the Isle of Dogs in 1910. From then until 1993, the club played at what is now called The Old Den in New Cross, before moving to its current home stadium nearby, called The Den. The traditional club crest is a lion rampant, referred to in the team's nickname 'The Lions'. Millwall's traditional kit consists of blue shirts, white shorts, and blue socks.
In Millwall's 92 seasons in the Football League from 1920-21 to 2018-19, the club have been promoted eleven times (five times as champions) and relegated nine times. We have spent the majority of our existence yo-yoing between the second and third tiers of English football. The club did have a brief spell in the top flight between 1988 and 1990, in which we achieved our highest ever league finish of tenth place in the First Division in 1988-89. Millwall reached the 2004 FA Cup final and qualified for Europe for the first time in our history, playing in the UEFA Cup. The club have also won two League One play-off finals in 2010 and 2017, the Football League Group Cup in 1983, and were Football League Trophy finalists in 1999.
In the media, Millwall's supporters have often been associated with hooliganism, with numerous films having been made fictionalising their notoriety. Our fans are renowned for their terrace chant 'No one likes us, we don't care'. Millwall have a long-standing rivalry with West Ham United. The local derby between the two sides has been contested almost a hundred times since 1899. The club also share a rivalry with Leeds United, and contest the South London derby with local rivals Crystal Palace and Charlton Athletic
