*Henry IV of France 

Henry IV (13 December 1553 – 14 May 1610), also known by the epithet "Good King Henry", was King of Navarre (as Henry III) from 1572 to 1610 and King of France from 1589 to 1610. He was the first French monarch of the House of Bourbon, a branch of the Capetian dynasty.

Baptised as a Catholic but raised in the Protestant faith by his mother Jeanne d'Albret, Queen of Navarre, he inherited the throne of Navarre in 1572 on the death of his mother. As a Huguenot, Henry was involved in the French Wars of Religion, barely escaping assassination in the St. Bartholomew's Day massacre, and later led Protestant forces against the royal army.
