Stockport County Football Club is a professional football club based in Edgeley, Stockport, England, which competes in EFL League One, the third tier of the English football league system. Formed in 1883 as Heaton Norris Rovers, the team adopted their name in 1890 after the County Borough of Stockport. They have played at Edgeley Park since 1902, traditionally in blue and white, and are nicknamed The Hatters after the town's former hat-making industry. Stockport County joined the Football League in 1900 and competed in it continuously from 1905 to 2011. The team spent most of their history in the lower reaches of the Football League, but the 1990s were more successful with the club competing in the First Division (now known as the Championship) for five seasons, whilst they also reached the League Cup semi-finals in 1996–97. However, instability on and off the pitch eventually led to Stockport falling back to the lower divisions. The club started the 2011–12 season in the Conference National, having been relegated from Football League Two for the first time in their history at the end of 2010–11. At the end of 2012–13, Stockport were relegated to the Conference North.
