During his reign, King Edward II faced several significant events and issues. These include:

Conflicts with the nobility: Edward had a difficult relationship with the nobility, particularly the barons. They were unhappy with his rule and the influence of his favorites, Piers Gaveston and later Hugh Despenser. This led to a series of rebellions against the king, known as the Edwardian War.

Deposition of Piers Gaveston: Gaveston was a close friend and advisor to the king, but the barons saw him as a corrupting influence. They eventually forced Edward to banish Gaveston, but he later recalled him, which led to further conflict.

The Despenser War: After Gaveston's death, Hugh Despenser became the king's favorite. The barons again saw him as corrupt and oppressive, and they rebelled against the king in what is known as the Despenser War.

Deposition and death: In 1326, Edward's own son, Edward III, led a successful rebellion against his father and had him deposed. He was imprisoned in Berkeley Castle, where he is believed to have been murdered on September 21, 1327.

Financial problems: King Edward II also faced financial problems, he spent a lot of money on his own pleasure, and also on his favorites, which led to the financial crisis of the kingdom.

Military failures: King Edward II also had a string of military failures during his reign, the most significant being the Battle of Bannockburn where the English army was defeated by the Scottish army. This led to the Scottish gaining independence from England.
