In 1483 after the death of Edward IV, Edward (age 24) led an uprising in Kent against Richard III and had to flee the country, but returned in 1485 to be knighted and serve Henry VII in the Netherlands, France and Ireland. He was sent to Ireland as Lord Deputy in 1494-5 to establish “Poynings Law”, whereby Irish administration was made directly dependent on the English Crown and privy council.  In 1497 he was presented to Hockwold church as Lord Warden of the Cinque-ports, and thereafter he was employed in negotiations with England’s allies on the continent. When he died in 1521, he had no surviving legitimate children, so Henry Percy, 5th Earl of Northumberland was found to be cousin and heir.
