Henry Beaufort, 3rd Duke of Somerset was a commander during which wars to control the throne of England between 1455-1487?
Wars of the Roses The Wars of the Roses were a series of wars for control of the throne of England fought between supporters of two rival branches of the royal House of Plantagenet: the House of Lancaster (associated with a red rose), and the House of York (whose symbol was a white rose). The conflict lasted through many sporadic episodes between 1455 and 1487; however, there was fighting before and after this period between the houses. The power struggle ignited around social and financial troubles following the Hundred Years' War, combined with the mental infirmity and weak rule of Henry VI which revived interest in Richard of York's claim to the throne. Historians disagree about whether the Wars of the Roses were caused by the structural problems of feudalism or Henry VI's ineffectiveness as king.
Edmund Mortimer, 5th Earl of March Edmund de Mortimer, 5th Earl of March and 7th Earl of Ulster (6 November 1391 – 18 January 1425) was an English nobleman. A great-great-grandson of King Edward III of England, he was heir presumptive to King Richard II of England, his first cousin twice removed, when Richard II was deposed in favour of Henry IV. Edmund Mortimer's claim to the throne was the basis of rebellions and plots against Henry IV and his son Henry V, and was later taken up by the House of York in the Wars of the Roses, though Mortimer himself was an important and loyal vassal of Henry V and Henry VI. Edmund Mortimer was the last Earl of March of the Mortimer family.
