The sport of rugby union has been played at the Summer Olympics on four occasions, with the last being in 1924. The winners, and thus the reigning champions, were the U.S. team. Rugby union made one more appearance as a demonstration event but was then removed from the Games. World Rugby has most recently been very keen to see it return to the Games and is adamant that the sport (specifically referring to rugby sevens) satisfies every respect of the criteria set out in the Olympic Charter.
