Conceived as a character-building exercise, the annual games and nations system were intended to foster a team spirit and encourage physical activity among all pupils. Within each nation, masters were appointed to committees to develop Under 15 and Under 13 cricket and rugby teams, and to broaden participation beyond the First XI and XV by training pupils of every level of ability. The competitive scheme proved popular with pupils and teachers and has since been expanded to encompass a wide variety of games, sports and other extracurricular activities, held throughout the year. Nation badges were introduced in 1928.
