The Wales national football team is the third-oldest side in international association football. The team played their first match in March 1876, four years after Scotland and England had contested the first-ever international match. Wales played annual fixtures against Scotland, England, and later Ireland, and these were eventually organised into the British Home Championship, an annual competition between the Home Nations. Wales did not win their first championship until the 1906–07 tournament and this remained the nation's only triumph before the First World War. Wales improved considerably in the post-war period, and claimed three titles during the 1920s, although the team was often hindered by the reluctance of Football League clubs to release their players for international duty. The situation was so grave that, in the early 1930s, Wales were forced to select a team of lower league and amateur players which became known as "Keenor and the 10 unknowns", a reference to captain Fred Keenor and the relative obscurity of his teammates.
