The Glasgow Merchants' Charity Cup was a knockout football tournament open to teams from in and around Glasgow and later on in the tournament's history, teams from outwith Glasgow. Invitations were made and sent out by the Glasgow Charity Cup Committee (GCCC) at their discretion, but no criteria were ever published.

The Old Firm is the collective name for the Scottish football clubs Celtic and Rangers, which are both based in Glasgow. The two clubs are the most successful and popular in Scotland, and the rivalry between them has become deeply embedded in Scottish culture. It has reflected and contributed to political, social and religious division and sectarianism in Scotland. As a result, matches between them have had an enduring appeal around the world.
