The first full-length study of one of the most controversial figures of later fourteenth century England. Robert de Vere was a close friend of the young King Richard II. He was accused of a wide range of political crimes and private vices by his opponents, the Lords Appellant. Defeated by them at the battle of Radcot Bridge in 1387, he died abroad in exile aged only 30. He was, in the eyes of many contemporaries - most notably the hostile chroniclers Walsingham and Froissart - and modern historians, a typical royal favourite: unmartial, immoral, self-seeking, and promoted and enriched far beyond what he deserved. But what was a royal favourite, and what were the accusations made against them? This book investigates these questions across late medieval England, and assesses de Vere against contemporary criteria. Based on extensive archival research, this book shows there was more to de Vere than a grasping courtier. He had been Earl of Oxford since the age of nine, heir to a large landed estate, and had twice served in foreign wars. He also made a serious attempt to govern the English lordship in Ireland given to him by Richard. The findings here show him to be a far more rounded and complex figure than previously assumed.
