House of York

The fourth surviving legitimate son of Edward III and Philippa of Hainault, Edmund of Langley, 1st Duke of York, was created earl of Cambridge in 1362 and the first duke of York in 1385. Edmund's first marriage was to Isabella of Castile, Duchess of York, daughter of Peter of Castile and María de Padilla, and sister of Constance of Castile, second wife of Edmund's older brother John of Gaunt. Through this marriage Edmund had two sons, Edward, 2nd duke of York and the younger Richard of Conisburgh. His second marriage was to Joan Holland, whose sister Alianore Holland was mother to Anne Mortimer, the great-great-granddaughter of Edward III via Lionel of Antwerp, Duke of Clarence, second surviving son of Edward III, and the elder brother of John of Gaunt. Richard of Conisburgh married Anne Mortimer, the marriage producing two children, Isabel of Cambridge and Richard of York, 3rd Duke of York. It was through Anne Mortimer's lineage that the Yorkists derived their main claim to the throne.

Following Edmund of Langley's death in 1402, his son Edward succeeded to the dukedom but had no issue before he was killed at the Battle of Agincourt in 1415.^[1] His other son Richard had been executed for treason earlier in the same year following his involvement in the Southampton Plot to depose Henry V in favour of Edmund Mortimer, Richard's brother-in-law. The dukedom therefore passed to Richard's son, who became Richard of York, 3rd Duke of York. Being descended from Edward III in both the maternal and the paternal line gave Richard a significant claim to the throne if the Lancastrian line should fail, and by cognatic primogeniture arguably a superior claim.^[2] He emphasised the point by being the first to assume the Plantagenet surname in 1448. Having inherited the March and Ulster titles, he became the wealthiest and most powerful noble in England, second only to the king himself. Richard married Cecily Neville, a granddaughter of John of Gaunt, and had thirteen or possibly fifteen children:^[3]

• Anne of York (1439–1476)—(Mitochondrial DNA taken from a descendant of her second daughter, Anne St Leger, Baroness de Ros, was used in the identification of the remains of Richard III, which were found in 2012.^[4])
• Henry (b. 1441; died as a child)
• Edward (1442–1483)
• Edmund (1443–1460)
• Elizabeth (1444–1503)—married John de la Pole, 2nd Duke of Suffolk; she was the mother of several claimants to the throne.
• Margaret (1446–1503)—married Charles the Bold, Duke of Burgundy.
• William (b. 1447; died as a child)
• John (b. 1448; died as a child)
• George (1449–1478)
• Thomas (b. 1450/51; died as a child)
• Richard (1452–1485)
• Ursula (b. 1455; died as a child)
• In her will, Cecily stated that Katherine and Humphrey were her children, but they may have been her grandchildren through de la Pole.

Despite his elevated status, Richard Plantagenet was denied a position in government by the advisers of the weak Henry VI, particularly John Beaufort, 1st Duke of Somerset, and the queen consort, Margaret of Anjou. Although he served as protector of the realm during Henry VI's period of incapacity in 1453–54, his reforms were reversed by Somerset's party once the king had recovered.

The Wars of the Roses began the following year, with the First Battle of St Albans. Initially, Richard aimed only to purge his Lancastrian political opponents from positions of influence over the king. It was not until October 1460 that he claimed the throne for the House of York. In that year the Yorkists had captured the king at the battle of Northampton, but victory was short-lived. Richard and his second son Edmund were killed at the battle of Wakefield on 30 December.

Richard's claim to the throne was inherited by his son Edward. With the support of Richard Neville, 16th Earl of Warwick ("The Kingmaker"), Edward, already showing great promise as a leader of men, defeated the Lancastrians in a succession of battles. While Henry VI and Margaret of Anjou were campaigning in the north, Warwick gained control of the capital and had Edward declared king in London in 1461. Edward strengthened his claim with a decisive victory at the Battle of Towton in the same year, in the course of which the Lancastrian army was virtually wiped out.

The early reign of Edward IV was marred by Lancastrian plotting and uprisings in favour of Henry VI. Warwick himself changed sides, and supported Margaret of Anjou and the king's jealous brother George, Duke of Clarence, in briefly restoring Henry in 1470–71. However, Edward regained his throne, and the House of Lancaster was wiped out with the death of Henry VI himself, in the Tower of London in 1471. In 1478, the continued trouble caused by Clarence led to his execution in the Tower of London; popularly he is thought to have been drowned in a butt of malmsey wine.

On Edward's death in 1483, the crown passed to his twelve-year-old son Edward V. Edward IV's younger brother Richard, Duke of Gloucester, was appointed Protector, and the young king, and his brother Richard, were accommodated into the Tower of London. The famous Princes in the Tower's fate remains a mystery. As today it is unknown whether they were killed or who might have killed them. Parliament declared, in the document Titulus Regius, that the two boys were illegitimate, on the grounds that Edward IV's marriage was invalid, and as such Richard was heir to the throne. He was crowned Richard III in July 1483.

Though the House of Lancaster's claimants were now the Royal Houses of Portugal and Castile through the Duke of Lancaster's two legitimate daughters, who had married into those houses, Henry Tudor, a descendant of the Beauforts, a legitimized branch of the House of Lancaster put forward his claim. Furthermore, some Edwardian loyalists were undeniably opposed to Richard, dividing his Yorkist power base. A coup attempt failed in late 1483, but in 1485 Richard met Henry Tudor at the battle of Bosworth Field. During the battle, some of Richard's important supporters switched sides or withheld their retainers from the field. Richard himself was killed. He was the last of the Plantagenet kings, as well as the last English king to die in battle.

Henry Tudor declared himself king, took Elizabeth of York, eldest child of Edward IV, as his wife, claiming to have united the surviving houses of York and Lancaster, and acceded to the throne as Henry VII, founder of the Tudor dynasty which reigned until 1603.

At the point Henry VII of England seized the throne there were eighteen Plantagenet descendants who might today be thought to have a stronger hereditary claim. By 1510 this number increased with the birth of sixteen Yorkist children.^[5] However, Henry VII married Elizabeth of York the eldest daughter of Edward IV. This made their children his cognatic heirs.^[6] Margaret of York, Duchess of Burgundy—Edward's sister—and members of the de la Pole family—children of Edward's sister Elizabeth and John de la Pole, 2nd Duke of Suffolk— continued in attempts to restore a Yorkist line.^[7] Margaret's nephew Edward, Earl of Warwick, the son of her brother George, was imprisoned in the Tower of London, but in 1487 Margaret financed a rebellion led by Lambert Simnel pretending to be Warwick, or "Edward VI". John de la Pole, 1st Earl of Lincoln, joined the revolt and was killed in the suppression of the uprising at the Battle of Stoke Field in 1487.^[8] Warwick was implicated in further failed invasions supported by Margaret by Perkin Warbeck claiming to be Edward IV's son Richard of Shrewsbury and executed on 28 November 1499. With this both the houses of Plantagenet and York went extinct in the legitimate male line.^[9]
