Henry, 3rd Duke of Guise (January 31, 1550 – December 23, 1588, Château de Blois), sometimes called Le Balafré, "the scarred", was the son of Francis, Duke of Guise.
The talent and dash of Guise contrasted favorably with the vacillation and weakness of Henry III, and he was said to have claimed a Carolingian descent and cast eyes on the throne.
This led to the stage of the Wars of Religion known as the War of the ThreeHenries.
The French Wars of Religion were a series of conflicts fought between Catholics and Huguenots (Protestants) from the middle of the sixteenth century to the Edict of Nantes in 1598, including civil infighting as well as military operations.
At Orléans, Francis, Duke of Guise was assassinated, and Catherine's fears that the war might drag on led her to negotiate a truce and the Edict of Amboise (1563).
The situation on the ground in 1590 was that King Henry IV of France, as Navarre had become, held the south and west, and the Catholic League the north and east.
