King Henry IV of France, also known as Henry of Navarre, was the first monarch of the House of Bourbon. He ruled from 1589 until his assassination in 1610. Henry was a key figure in the French Wars of Religion, converting from Protestantism to Catholicism to unify France and promote peace. Henry IV is best known for issuing the Edict of Nantes in 1598, which granted religious tolerance to Huguenots and helped end the civil strife. His reign is often remembered for efforts to improve the economy and infrastructure of France, earning him the nickname "Good King Henry."
