Early versions of football were played in the present-day United States as early as 1685, and freshmen at Harvard University in 1734 were asked to provide "foot-balls". This resembled modern soccer only in kicking activities, and was often violent. Several sets of rules began to be codified by the 1860s, such as the "Boston game" a combination of rugby football and soccer.
