Between 1872 and 1914, when competitive football was interrupted by the First World War, Scotland played 113 international matches, resulting in 70 victories, 23 draws and 20 defeats. This total does not include a match in 1902 which was declared void after a disaster at Ibrox Park in which 25 spectators died. Scotland played an annual friendly against England each year until 1883, and added a regular game against Wales in 1876. These two teams remained Scotland's only opponents until the British Home Championship was instituted in 1884, consisting of a round-robin tournament between England, Scotland, Wales and Ireland. Of the 31 tournaments staged prior to the war, Scotland won 10 outright and 6 jointly. Scotland's 11–0 defeat of Ireland in 1901 is the national team's biggest win, and the 6–1 victory over England at Kennington Oval in 1881 remains the team's biggest win away to fierce rivals England. Scotland's games with England during this period drew extremely large crowds, with five matches prior to the First World War attracting crowds of over 100,000 spectators. The compilers of the World Football Elo Ratings retrospectively consider Scotland to have been ranked at number 1 during much of the early period of international football.
