On July 25, 1593, Henri IV of France made a pivotal decision that would reshape religious politics by converting from Protestantism to Catholicism, famously declaring "Paris is worth a Mass." This strategic religious pivot effectively ended the French Wars of Religion, a brutal conflict that had torn the nation apart for decades. The conversion was so politically calculated that the Protestant leader Henri of Navarre reportedly quipped, "God is great, but good politics are greater." His shrewd maneuver effectively neutralized the Catholic League's opposition and paved the way for the Edict of Nantes, which granted unprecedented religious tolerance in 16th-century Europe. The moment was both a personal transformation and a masterclass in political maneuvering, demonstrating how a single monarch's decision could dramatically alter a nation's trajectory. Henri's pragmatic approach—essentially trading theological conviction for political stability—became a blueprint for diplomatic compromise that would influence European statecraft for generations. By choosing political unity over doctrinal purity, he not only secured his own throne but also initiated a period of relative peace in a nation exhausted by religious bloodshed.
