John of Gaunt, 1st Duke of Lancaster (second creation), KG (6 March 1340 – 3 February 1399) was a member of the House of Plantagenet, the third surviving son of King Edward III of England and Philippa of Hainault. He was called "John of Gaunt" because he was born in Ghent, rendered in English as Gaunt. When he became unpopular later in life, scurrilous rumours and lampoons circulated that he was actually the son of a Ghent butcher, perhaps because Edward III was not present at the birth. This story always drove him to fury.[1] As a younger brother of Edward, Prince of Wales (Edward, the Black Prince), John exercised great influence over the English throne during the minority of his nephew, Richard II, and during the ensuing periods of political strife, but was not thought to have been among the opponents of the king. John of Gaunt's legitimate male heirs, the Lancasters, included Kings Henry IV, Henry V, and Henry VI. His other legitimate descendants included, by his first wife, Blanche, his daughters Queen Philippa of Portugal and Elizabeth, Duchess of Exeter; and by his second wife, Constance, his daughter Queen Catherine of Castile. John fathered five children outside marriage, one early in life by a lady-in-waiting to his mother, and four surnamed "Beaufort" (after a former French possession of the Duke) by Katherine Swynford, Gaunt's long-term mistress and third wife. The Beaufort children, three sons and a daughter, were legitimised by royal and papal decrees after John and Katherine married in 1396; a later proviso that they were specifically barred from inheriting the throne, the phrase excepta regali dignitate (English: not eligible for the royal dignity), was inserted with dubious authority by their half-brother Henry IV. Descendants of this marriage included Henry Beaufort, Bishop of Winchester and eventually Cardinal; Joan Beaufort, Countess of Westmorland, grandmother of Kings Edward IV and Richard III; John Beaufort, 1st Earl of Somerset, the great-grandfather of King Henry VII; and Joan Beaufort, Queen of Scots, from whom are descended, beginning in 1437, all subsequent sovereigns of Scotland, and successively, from 1603 on, the sovereigns of England, of Great Britain and Ireland, and of the United Kingdom to the present day. The three succeeding houses of English sovereigns from 1399 — the Houses of Lancaster, York and Tudor — were descended from John through Henry Bolingbroke, Joan Beaufort and John Beaufort, respectively. When John died in 1399, his estates were declared forfeit as King Richard II had exiled John's son and heir, Henry Bolingbroke, in 1398, for 10 years. Bolingbroke returned from exile to reclaim his inheritance and depose Richard. Bolingbroke then reigned as King Henry IV of England (1399–1413), the first of the descendants of John of Gaunt to hold the throne of England.
