Edward III created the Duchy of Cornwall as an estate for the Black Prince; A.L. Rowse describes how it has been held ever since by the sovereign’s heir or lain dormant in the Crown.
The eldest son of Edward III took a decisive part in the battles of the Hundred Years’ War and was regarded as a paragon of chivalry. C.T. Allmand describes how the Black Prince, as he would become known, was his father’s chief lieutenant in Aquitaine, 1355-72.
