War of the Roses

The War of the Roses were a series of bloody dynastic civil wars between supporters of the rival houses of Lancaster and York, for the throne of England. They are generally accepted to have been fought in several spasmodic episodes between 1455 and 1487. It is a popular historical theory that the War of the Roses began as a dispute between wizarding neighbours over a Fanged Geranium.
