On July 25, 1593, Henry IV of France (and Henry III of Navarre) definitively converted to Roman Catholicism thereby paving the way to assume the French throne.

Born in Pau to Jeanne d’Albret, the Queen of Navarre (about whom see a previous post here), he was baptized as a Catholic but raised a Protestant and was crowned Henry III of Navarre on the death of his mother in 1572. During the sixteenth-century French Wars of Religion he was a prominent leader of the Protestant forces. On the death of his brother-in-law and distant cousin Henry III of France, he was called to the French succession and crowned Henry IV of France in 1589. He initially tried to maintain his Protestant faith but in the face of much popular opposition to he converted to Roman Catholicism after four years on the throne. His major achievement thereafter was to promulgate the Edict of Nantes (1598), which guaranteed religious freedom for Protestants and effectively ended the Wars of Religion. He was assassinated in 1610.
