Philippa of Hainault (d. 1369)
Philippa of Hainault (sometimes spelled Hainaut; Middle French: Philippe de Hainaut; 24 June 1310 (or 1315) – 15 August 1369) was Queen of England as the wife and political adviser of King Edward III. She acted as regent in 1346, when her husband was away for the Hundred Years' War.

Daughter of Count William of Hainaut and French princess Joan of Valois, Philippa was engaged to Edward, Prince of Wales, in 1326. Their marriage was celebrated in York Minster on 24 January 1328, some months after Edward's accession to the throne of England and Isabella of France's infamous invasion. After her husband reclaimed the throne, Philippa influenced King Edward to take interest in the nation's commercial expansion, was part of the successful Battle of Neville's Cross, and often went on expeditions to Scotland and France. She won much popularity with the English people for her compassion in 1347, when she successfully persuaded the King to spare the lives of the Burghers of Calais. This popularity helped maintain peace in England throughout their long reign.
