A vigorous warrior-king whose fatal jousting accident plunged France into decades of religious civil war.
Henry II of France ascended the throne in 1547, inheriting a kingdom deeply in debt from his father's wars but also a fierce rivalry with the Habsburg Empire. A robust and athletic man, he preferred physical pursuits and the company of his powerful mistress, Diane de Poitiers, over the minutiae of governance, which he largely left to the constable Anne de Montmorency. His reign was defined by continued conflict, most notably the final phase of the Italian Wars, which ended with France's defeat at Saint-Quentin. Domestically, his policies intensified the persecution of French Protestants, or Huguenots, laying the kindling for the Wars of Religion that would erupt after his death. His life ended with shocking suddenness during a tournament to celebrate peace treaties; a splinter from a broken lance pierced his eye, leading to a gruesome death days later. This tragic accident created a power vacuum, leaving the kingdom to his young and sickly sons and his formidable widow, Catherine de' Medici, who struggled to control the spiraling religious violence.
