Answer:
Henry IV of France rebuilt and reunited France after the long War of Religions, which lasted from 1562 to 1598. He made the first attempt to bring peace to the Catholics and Protestants in the Modern Era through the Edict of Nantes, which granted Protestants the ability to practice their religion in France, a Catholic kingdom at the time. Working with Maximilian de Béthune, duc de Sully, he regulated state finance, promoted agriculture, and made several commercial treaties with both Spain and the Ottoman Empire, increasing foreign trade for the nation. Also, he sponsored the expeditions of several explorers to the New World, ensuring that France laid claim to Canada.
And that's really all I can think of right now.
