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.
The Wars were fought largely by armies of mounted knights and their feudal retainers. The House of Lancaster found most of its support in the north and west of the country, while support for the House of York came mainly from the south and east. The Wars of the Roses, with their heavy casualties among the nobility, were a major factor in the weakening of the feudal power of the nobles, leading to the growth of a strong, centralised monarchy under the Tudors.
