Henry IV of France, also known as Henry of Navarre, was the first monarch of the House of Bourbon who ruled from 1589 to 1610. He is best known for his efforts to end the Wars of Religion in France, promoting tolerance and peace through the Edict of Nantes, which granted religious freedom to Protestants. His reign marked a significant shift towards absolutism, as he strengthened royal authority while navigating the complex political landscape of his time.
