Its assumed that you mean who played Rugby first?
If so then its the Students of Rugby School. Warwickshire. England in 1823. When a student who was playing football picked picked up the ball (which was allowed then) and instead of running backward to pass to a team mate (which was the rule) he ran forward toward the line). The pupils that left and went ton to university at that time took the ball carrying idea with them. One of the first rugby teams was brought together by Arthur Pell, for example, who set up a club at Cambridge University in 1839 and, of significance to football historians per se, the 1848 meeting which led to the 'Cambridge Rules' in 1848 was the result of a game between the Old Rugbeians and the Old Etonians - the latter growing exasperated at the Rugby players' use of hands. The oldest 'football club' was also the product of former Rugbeians, when Guy's Hospital FC was founded in 1843, soon followed by others such as Dublin University FC in 1854 and Blackheath Rugby Club in 1858.
