This Day in History: 1286-06-30
On 30th June 1286, John de Warenne, 7th Earl of Surrey, was born. He succeeded his grandfather, John de Warenne (his father having been killed in a tournament when he was only six months old), in September 1304 as Earl of Surrey, becoming a ward of Edward I. He was eight years old when his mother died. In 1306, he was married to King Edward I‘s granddaughter, Joan of Bar, when she was only ten. The marriage was unsuccessful and Joan was largely abandoned by her husband who had been trying to divorce her since 1313. John would have numerous illegitimate children during his life and would take ownership of Sandal Castle in 1304 at the age of eighteen. De Warenne’s aunt, Isabella de Warenne, was married to John Balliol, who became king of Scotland in 1292.
