Roger Mortimer

The Most Traitorous Earl of Edward II's Court

Definition

Roger Mortimer, 1st Earl of March (1287-1330) was an English nobleman who deposed King Edward II of England (reign 1307-1327) and then established himself as the kingdom's de facto ruler. Though he had initially been loyal to the king, Mortimer eventually became disillusioned with Edward's reign and rebelled. He was captured and imprisoned in the Tower of London, but he made a daring escape and fled to Paris. There, he conspired with Queen Isabella of France – Edward II's wife and Mortimer's lover – to invade England, which they successfully did in late 1326. After forcing Edward II's abdication, Mortimer and Isabella briefly ruled as joint regents. However, Mortimer's corruption and unpopularity soon led to his downfall. The new King Edward III of England staged a coup, and Mortimer was arrested and executed in 1330.
