Westminster Chronicle of King Richard II, 1381-1394
The Westminster Chronicle is one of the most vivid and important narrative sources for the reign of Richard II. Written by an anonymous chronicler closely connected with Westminster Abbey, it covers the years 1381 to 1394, from the Peasants’ Revolt to the political tensions, court ceremonies, diplomatic negotiations, royal progresses, and public crises of Richard’s later reign. Rich in detail the chronicle records major events such as the conflicts between the King and Lords Appellant, King and the City of London, negotiations with France and Scotland, the death and funeral of Queen Anne of Bohemia, the illness of Charles VI of France, and the changing fortunes of leading nobles including John of Gaunt, Thomas of Gloucester, Robert de Vere, and the Earl of Arundel. The Chronicle offers readers a remarkable window into late fourteenth-century England, combining political observation, courtly spectacle, urban drama, ecclesiastical affairs, and moral judgement. It is an essential source for anyone interested in medieval monarchy, London, Westminster, and the troubled reign of Richard II.
