Crystal Palace Football Club is an English professional football club based in Selhurst, South London, that competes in the Premier League, the highest level of English football. They were founded in 1905 at the famous Crystal Palace Exhibition building and played their home games at the FA Cup Final stadium situated inside the historic Palace grounds. The club were forced to leave the Palace in 1915 due to the outbreak of the First World War, and played at Herne Hill Velodrome and the Nest until 1924, when they moved to their current home at Selhurst Park.
The club spent its early years in the Southern League before joining the Football League in 1920, and becoming the first ever champions of the newly formed Third Division in 1920–21. Since 1964, Palace have mainly played in the top two leagues of English football and have only dropped below the second tier once, for three seasons between 1974 and 1977. During the late 1980s and early 1990s, Palace became a force in the top flight, reaching the 1990 FA Cup Final, and finishing in third place in the top division in 1990–91, their highest league position to date.
