The War of the Three Henrys (1587-1589) was the eighth and final conflict in the series of civil wars in France known as the Wars of Religion. The war was fought between the royalists, led by Henry III of France; the Huguenots, led by the heir-presumptive Henry of Navarre; and the Catholic League, led by Henry I, Duke of Guise and funded and supported by Philip II of Spain. The war was instigated by King Philip to keep Spain's enemy, France, from interfering with the Spanish army in the Netherlands and his planned invasion of England and Russia.
