Edmund of Woodstock, 1st Earl of Kent
Edmund of Woodstock, 1st Earl of Kent was the sixth son of Edward I of England, and a younger halfbrother of Edward II. Edward I had intended to make substantial grants of land to Edmund, but when the king died in 1307, Edward II failed to follow through on his fathers intentions, much due to his favouritism towards Piers Gaveston. Edmund still remained loyal to his brother, and in 1321 he was created Earl of Kent. He played an important part in Edwards administration, acting both as diplomat and military commander, and in 132122 helped suppress a rebellion against the king.
Edward I of England had a great number of children with his first wife, Eleanor of Castile, but only one son who survived into adulthood the future Edward II . After Eleanor died, the king married Margaret of France, with whom he had two children Thomas and, when the king was sixtytwo, Edmund. Edmund was born at Woodstock in Oxfordshire onAugust 1301, and was therefore referred to as Edmund of Woodstock. Son of the English king, he was also, through his mother, grandson of Philip III of France. OnJuly 1307, before Edmund had turned six, King Edward I died, leaving Edmunds halfbrother Edward to succeed as King Edward II.
