Edward III (13 November 1312 – 21 June 1377), also known as Edward of Windsor before his accession, was King of England from January 1327 until his death in 1377. He is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II.
Edward III transformed the Kingdom of England into one of the most formidable military powers in Europe. His fifty-year reign was one of the longest in English history, and saw vital developments in legislation and government, in particular the evolution of the English Parliament, as well as the ravages of the Black Death. He outlived his eldest son, Edward the Black Prince, and was succeeded by his grandson Richard II.
Philippa of Hainault
Philippa of Hainault (sometimes spelled Hainaut; Middle French: Philippe de Hainaut; 24 June 1310 (or 1315)[1][2][3] – 15 August 1369) was Queen of England as the wife and political adviser of King Edward III.[4] She acted as regent in 1346,[5] when her husband was away for the Hundred Years' War.
Daughter of William I, Count of Hainaut, and French princess Joan of Valois, Philippa was engaged to Edward, Prince of Wales, in 1326.[6] 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.[7] 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.[8]
