Charlton Athletic

Charlton Athletic Football Club (also known as The Addicks) is a professional association football club based in Charlton, in the London Borough of Greenwich. The club was founded on 9 June 1905, when a number of youth clubs in the South-East London area, including East Street Mission and Blundell Mission, combined to form Charlton Athletic Football Club. The club is based at The Valley, where it has played since 1919, apart from one year in Catford, during 1923–24, and seven years at Crystal Palace and West Ham United between 1985 and 1992. Charlton turned professional in 1920 and first entered the Football League in 1921. Since then, they have had four separate periods in the top flight of English football: between 1936 and 1957; 1986 and 1990; 1998 and 1999, and 2000 to 2007. Historically, Charlton's most successful period was the 1930s, when the club's highest league finishes were recorded, including runners-up of the league in 1937, and after World War II, when the club reached the FA Cup final twice, winning in 1947. After being relegated from the Championship in 2008–09, they play in Football League One as of the 2009–10 season.
