Arsenal was founded in 1886 in Woolwich and in 1893 became the first club from the south of England to join the Football League. In 1913, it moved north across the city to Arsenal Stadium in Highbury. In the 1930s the club won five League Championship titles and two FA Cups. After a lean period in the post-war years it won the League and FA Cup Double, in the 1970–71 season, and in the 1990s and first decade of the 21st century won two more Doubles and reached the 2006 UEFA Champions League Final. Arsenal has a long-standing rivalry with North London neighbours Tottenham Hotspur, with whom it contests the North London derby. Arsenal is the fourth most valuable association football club in the world as of 2012, valued at $1.3 billion.
