Wars of the Roses
From Wikipedia, the free encyclopedia.
The Wars of the Roses (1455–1487) is the name generally given to the intermittent civil war fought over the throne of England between adherents of the House of Lancaster and the House of York. Both houses were branches of the Plantagenet royal house, tracing their descent from King Edward III. The name Wars of the Roses was not used at the time, but has its origins in the badges chosen by the two royal houses, the Red Rose of Lancaster and the White Rose of York.
