What religion were French Kings?

Answer 1

The kings of France were all Catholic with one exception and even he converted. This King was King Henry IV--first Bourbon king of France(and grandfather of Louis XIV). He was a Protestant and was the king of Navarre, a smaller French kingdom. He married the sister of the French king(Queen Margot)and he was their first cousin. Despite Margot having many brothers, they died one by one and the throne was Henry's. Many of the towns in France refused to be ruled by a Protestant so he had to fight and claim several of them. The last holdout was Paris--the capital. Paris did not fall even after a prolonged siege. When asked if he would convert to gain the capital, Henry is said to have replied that, "Paris is worth a mass" and converted to Catholicism and was crowned as King of France and Navarre.
