Old Firm

The Old Firm is the collective name for the Glasgow association football clubs Celtic and Rangers. The origin of the term is unclear but may derive from the two clubs initial match in which the commentators referred to the teams as "like two old, firm friends", and represents the commercial benefits of the two clubs' rivalry. The name may also be a reference to these two teams being among the original 11 members of the Scottish Football League formed in 1890. The rivalry between the two clubs deeply embedded Scottish culture and had contributed to the political, social and religious division in Scotland. As a result, the fixture was recognised as having enduring appeal.
