Final answer:
The Bourbon, Guise, and Montmorency families were the three noble families that fought for control of France during the French Wars of Religion, culminating in the rise of Henry IV who issued the Edict of Nantes.
Step-by-step explanation:
The three noble families that sought control over France during the French Wars of Religion were the Bourbon, Guise, and Montmorency families. These conflicts are epitomized in the War of the Three Henrys, during which Henry III of the Valois dynasty, Henry of Guise representing the Catholic League, and Henry of Navarre from the Bourbon family, all vied for power. After the death of the other two Henrys, Henry of Navarre stood victorious and ascended to the throne as Henry IV. In an effort to bring peace, Henry IV, originally a Protestant, converted to Catholicism and issued the Edict of Nantes in 1598, granting liberty of conscience and worship to the French Protestants known as the Huguenots, which brought stability to France.
