Philippa of Clarence also known as Philippa Plantagenet or Philippa de Burgh or Philippa of Eltham (16 August 1355 – 5 January 1382) was a medieval English princess and the suo jure Countess of Ulster.

Biography

She was born at Eltham Palace in Kent on 16 August 1355, the only child of Lionel of Antwerp, 1st Duke of Clarence, and Elizabeth de Burgh, 4th Countess of Ulster. Her father was the second surviving son of King Edward III of England and Philippa of Hainault. She was the eldest grandchild of King Edward and Queen Philippa, her namesake.

Philippa married Edmund Mortimer, 3rd Earl of March, at the age of fourteen, in the Queen's Chapel at Reading Abbey. Her cousin, King Richard II, remaining childless, made Philippa and her descendants next in line to the throne until his deposition. In the Wars of the Roses, the Yorkist claim to the crown was based on descent from Edward III through Philippa, her son Roger Mortimer, and granddaughter Anne Mortimer, who married Richard of Conisburgh, 3rd Earl of Cambridge, a son of her uncle Edmund of Langley, 1st Duke of York.

Philippa died in around 1377. The precise date of her death is unknown, but Philippa had certainly died by December 1379. Her date of death is often confused with that of her mother-in-law, who died in January 1382. Philippa was buried at Wigmore Abbey, Herefordshire.
