Scotland was one of the earliest modern footballing nations, with Glasgow club Queen's Park early pioneers of the game throughout the UK. More clubs formed in Scotland, resulting in the commencement of the first major competition in 1873, the Scottish Cup, then the founding of the Scottish Football League in 1890. With the official sanctioning of professionalism, the Old Firm of Celtic and Rangers became dominant in Scotland, and remain so, although other clubs have enjoyed brief periods of success too.
