The lower divisions of the 2015 Rugby Europe Sevens were the first with a new classification, where prior years split Division B into two geographical zones. For the inaugural year of the format, Division C was held in Zenica, Bosnia and Herzegovina, with twelve teams contesting five spots for Division B. Division B then played a twelve-team tournament in Zagreb, Croatia, with the two top-placing teams advancing to the 2016 Trophy, and the champion advancing to the Rugby Europe repechage tournament for a chance to qualify for the Olympic qualification tournament.
Ireland dominated the competition, winning all six matches, while scoring 47 tries and conceding only four.[1] Their try scoring was led by Adam Byrne (8), followed by captain Tom Daly (7), and Alex Wootton (6).[1]
