Edward II ascended to the English throne in 1307, beginning a turbulent twenty-year reign that would ultimately expose the inherent fragility of medieval kingship. His time as monarch was defined by persistent political friction between the Crown and the leading nobility, as well as a series of military setbacks that undermined his authority. Most notably, his forces suffered a significant defeat against the Scots at the Battle of Bannockburn in 1314, a failure that severely damaged his standing among the ruling classes.

A central source of domestic instability throughout his rule was the King's close relationships with controversial royal favourites, most prominently Piers Gaveston and Hugh Despenser. These associations drew the ire of the powerful barons, who viewed the influence of these men as an affront to traditional governance and a threat to their own political standing. The resulting resentment fostered a climate of deep suspicion and open rebellion that plagued the administration for much of the period.

The internal strife and perceived incompetence of the King eventually led to his downfall. In 1327, Edward II was deposed, marking a rare and dramatic collapse of royal power during the medieval era. His removal from the throne serves as a stark illustration of the consequences of failing to balance the demands of the nobility with the responsibilities of the monarchy. Key aspects of his reign include:

• The persistent and damaging political conflict with the English nobility.
• The controversial reliance on royal favourites such as Piers Gaveston and Hugh Despenser.
• The military defeat at the Battle of Bannockburn in 1314.
• The eventual deposition of the King in 1327.
