The Roses Tournament is an annual sports competition between Lancaster University and the University of York in England, often described as the largest inter-university sports tournament in Europe. It is organised by their respective Students' Unions, YUSU and LUSU. It takes its name from the 15th-century civil war, the Wars of the Roses, between the House of Lancaster and the House of York. The counties of Lancashire and Yorkshire are traditionally symbolized by the red and the white rose respectively, although York teams today play in gold and black kits. The competition is held every year during the early May bank holiday weekend, alternating its venue between the two universities.
