The history of Burnley Football Club, an English professional association football club, includes an FA Cup win when they defeated Liverpool in the 1914 final, and two top-flight league titles: in the 1920–21 season after a 30-match unbeaten run, and in 1959–60 under manager Harry Potts, with a last-day victory over Manchester City. Founded on 18 May 1882 in Burnley, Lancashire, by Burnley Rovers rugby club members, Burnley F.C. were one of the twelve founder members of the Football League, in 1888–89. From the 1950s until the 1970s under chairman Bob Lord, the club became known for its youth policy and scouting system, and was one of the first to set up a purpose-built training ground. Frequently promoted and relegated, they prevented relegation to the highest level of non-League football on the last matchday in 1986–87. By winning the Fourth Division, in 1991–92, they became the second team to win all four professional divisions of English football. (This article is part of a featured topic: Burnley F.C.)
