The history of the Scotland national football team dates back to the first ever international football match in 1872.
 Until the Second World War, Scotland mainly competed against the other Home Nations in the British Home Championship, with the most keenly contested fixture being the match with England.
 The Scottish Football Association, which governs the team, joined the international governing body FIFA in 1910, but along with the other Home Nations withdrew from FIFA in 1928.
 This meant that Scotland did not participate in the World Cups of 1930, 1934 or 1938.
 The Home Nations rejoined FIFA after the Second World War and Scotland then started to participate in international competitions.
 Scotland have since participated in eight World Cups and two European Championship tournaments, but have never progressed beyond the first stage.
 Scotland have not qualified for a tournament since the 1998 World Cup.
