Answer:
Isabella and Roger Mortimer led a rebellion against King Edward II of England in 1326, with the aim of removing him from the throne and placing Isabella's son, Edward III, in power.
Isabella was the wife of Edward II, but their marriage had broken down due to his infidelity and poor leadership. She had been sent to France to negotiate a peace treaty, but instead, she entered into an alliance with Roger Mortimer, an exiled English nobleman who had a personal vendetta against Edward II.
Together, Isabella and Mortimer assembled a force of mercenaries and disaffected English nobles and landed in England in September 1326. They were able to gain support from many English nobles who were dissatisfied with Edward's rule, and they quickly took control of several key towns and castles.
Edward II's army was no match for Isabella and Mortimer's forces, and he was eventually captured and forced to abdicate in favor of his son, Edward III. Edward II was imprisoned in Berkeley Castle, where he died under mysterious circumstances in 1327, leading to speculation that he was murdered on the orders of Mortimer and Isabella.
Isabella and Mortimer ruled England as regents for the young Edward III, but their rule was marked by corruption and a lack of popular support. In 1330, Edward III, with the help of loyal nobles, overthrew Mortimer and had him executed for treason. Isabella was placed under house arrest and lived the rest of her life in seclusion.
Overall, Isabella and Mortimer's rebellion against Edward II was successful in achieving their aim of removing him from power and placing Edward III on the throne. However, their rule was unpopular, and they were eventually overthrown themselves, leading to a period of instability and conflict in English politics.
