Blackpool Football Club are an English football club founded in 1887 from the Lancashire seaside town of Blackpool. They are competing in the 2011–12 season of the The Championship, the second tier of professional football in England, having been relegated from the Premier League at the end of the 2010–11 campaign. It was their debut season in the Premier League, and it was their first appearance in England's top flight since 1971. They hold the record for being the only club in English football to be promoted through all four divisions via the play-offs. The club's home ground has been Bloomfield Road since 1901, and their main nicknames are the Seasiders, the 'Pool and the Tangerines, the latter in reference to the colour of their home kit, which is often mistaken for orange. Their motto is Progress, as featured on the club crest. They have a fierce local rivalry with Preston North End, who currently play in the third tier. Meetings between the two clubs are known as the West Lancashire derby.
