The execution of a royal prince was a great provocation to the seventeen-year-old Edward III, who had not been informed about the decision, and it probably contributed to the king's decision to rise up against his protector. In October 1330, Edward III carried out a coup installing himself in personal control of government, and Mortimer was executed. Among the charges against Mortimer was that of procuring Edmund's death, and the charges against the late earl of Kent were annulled. In late 1325, Edmund had married Margaret Wake, sister of Thomas Wake, Baron Wake of Liddell, and the couple had several children. His lands and titles descended on his oldest son by the same name, but this Edmund himself died in October 1331. The earldom then passed to the younger son John.
