American military institutions importantly shaped the popular sport of college football. From support at its two oldest service academies, interest in football spread through military units across the country with military actors involved in the formation of the country's first collegiate athletic conference and the National Collegiate Athletic Association. Subsequently, the US military functioned as an agent of authoritative diffusion, fostering interest in college football after the First World War. Furthermore, military institutions, including the draft, affected not only which team would be most successful during the Second World War but also how civilians would play the game. These effects call to mind Charles Tilly's work on state formation and security-driven resource extraction as well as Harold Lasswell's garrison state idea.
