Question

Who helped Isabelle the Fair overthrow her husband?

Answer 1

Roger Mortimer, was her lover, and probably killed , or ordered the death of Edward II.

Answer 2

Roger de Mortimer, 1st Earl of March (25 April 1287 – 29 November 1330), an English nobleman, was for three years de facto ruler of England, after leading a successful rebellion against Edward II. He was himself overthrown by Edward's son, Edward III. Mortimer was also the lover of Edward II's wife, Isabella of France, who assisted him in the deposition of her husband.

In 1323 Queen Isabella, wife of Edward II, anxious to escape from her husband, obtained his consent to her going to France to use her influence with her brother, King Charles IV, in favour of peace. At the French court the queen found Roger Mortimer; she became his mistress soon afterwards, and at his instigation refused to return to England so long as the Despensers retained power as the king’s favourites.

The scandal of Isabella’s relations with Mortimer compelled them both to withdraw from the French court to Flanders, where they obtained assistance for an invasion of England. Landing in England in September 1326, they were joined by Henry, Earl of Lancaster; London rose in support of the queen, and Edward took flight to the west, pursued by Mortimer and Isabella.

After wandering helplessly for some weeks in Wales, the king was taken prisoner on 16 November, and was compelled to abdicate in favour of his son. Though the latter was crowned as Edward III on January 25, 1327, the country was ruled by Mortimer and Isabella, who were widely believed to have arranged the murder of Edward II in the following September at Berkeley Castle.
