King Edward III in the context of "Battle of Crécy"

Richard II (6 January 1367 – c. 14 February 1400), also known as Richard of Bordeaux, was King of England from 1377 until he was deposed in 1399. He was the son of Edward, Prince of Wales (later known as the Black Prince), and Joan, Countess of Kent. Richard's father died in 1376, leaving Richard as heir apparent to his grandfather, King Edward III; upon the latter's death, the 10-year-old Richard succeeded to the throne.

During Richard's first years as king, government was in the hands of a series of regency councils, influenced by Richard's uncles John of Gaunt and Thomas of Woodstock. England at that time faced various problems, most notably the Hundred Years' War. A major challenge of the reign was the Peasants' Revolt in 1381, and the young king played a central part in the brutal suppression of this crisis. Less warlike than either his father or grandfather, he sought to bring an end to the Hundred Years' War. A firm believer in the royal prerogative, Richard restrained the power of the aristocracy and relied on a private retinue for military protection instead. In contrast to his grandfather, Richard cultivated a refined atmosphere centred on art and culture at court, in which the king was an elevated figure.

Duke of Cornwall (Cornish: Duk a Gernow) is a title in the Peerage of England, traditionally held by the eldest son of the reigning British monarch, previously the English monarch. The Duchy of Cornwall was the first duchy created in England and was established in a royal charter in 1337 by King Edward III. In 2022, Prince William became Duke of Cornwall with the accession to the throne of his father, King Charles III; William's wife, Catherine, became Duchess of Cornwall.
