Edmund of Woodstock, 1st Earl of Kent (5 August 130119 March 1330), whose seat was Arundel Castle in Sussex, was the sixth son of King Edward I of England, and the second by his second wife Margaret of France, and was a younger half-brother of King Edward II. Edward I had intended to make substantial grants of land to Edmund, but when the king died in 1307, Edward II refused to respect his father's intentions, mainly due to his favouritism towards Piers Gaveston. Edmund remained loyal to his brother, and in 1321 he was created Earl of Kent. He played an important part in Edward's administration as diplomat and military commander and in 1321–22 helped suppress a rebellion. Discontent against the King grew and eventually affected Edmund. The discontent was largely caused by Edward's preference for his new favourites, Hugh Despenser the Younger and his father. In 1326, Edmund joined a rebellion led by Queen Isabella and Roger Mortimer, whereby King Edward II was deposed. Edmund failed to get along with the new administration, and in 1330 he was caught planning a new rebellion and executed. Once the new king, Edward III, came of age and assumed personal control of the government, he posthumously annulled the charges against his uncle. The title and estates of the Earl of Kent descended on Edmund's son, also called Edmund. When this Edmund died, in 1331, his brother John became earl. Though he was officially exonerated, Edmund did not enjoy a great reputation during his life and afterwards, due to his unreliable political dealings. Family background and early years 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 (born 1284). After Eleanor died, the king married Margaret of France, with whom he had two children who survived to adulthood: Thomas (born 1300) and, when the king was sixty-two, Edmund. Edmund was born at Woodstock in Oxfordshire on 5 August 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. On 7 July 1307, before Edmund had turned six, King Edward I died, leaving Edmund's half-brother Edward to succeed as King Edward II. Though not resident in the two boys' household, Edward I had taken great interest
