Isabella of France (c. 1295 – 22 August 1358), sometimes described as the She-Wolf of France (French: Louve de France), was Queen of England as the wife of King Edward II, and de facto regent of England from 1327 until 1330. She was the youngest surviving child and only surviving daughter of King Philip IV of France and Joan I of Navarre. Isabella was notable in her lifetime for her diplomatic skills, intelligence, and beauty. She overthrew her husband, becoming a "femme fatale" figure in plays and literature over the years, usually portrayed as a beautiful but cruel and manipulative figure.
Isabella arrived in England at age 12 during a period of growing conflict between the king and the powerful baronial factions. Her new husband was notorious for the patronage he lavished on his favourite, Piers Gaveston, but the queen supported Edward during these early years, forming a working relationship with Piers and using her relationship with the French monarchy to bolster her own authority and power. After the death of Gaveston at the hands of the barons in 1312, however, Edward turned to a new favourite, Hugh Despenser the Younger, and attempted to take revenge on the barons, resulting in the Despenser War and a period of internal repression across England. Isabella could not tolerate Hugh Despenser, and by 1325, her marriage to Edward was at a breaking point.
