Henri IV

First Bourbon  king of France (1589 – 1610) and king of Navarra (as Henry III, 1572 – 89), one of the most popular figures in French history.
Henry was brought up as a Protestant and received his military training from the Huguenot leader Gaspard II de Coligny in the Wars of Religion. He married Margaret of Valois in 1572; the marriage provided the opportunity for the Massacre of Saint Bartholomew's Day six days later.

Henry was held at the French court from 1572 to 1576, when he escaped to join the forces against Henry III. He fought the War of the Three Henrys and prevailed as unrivaled leader. He became king after Henry III was assassinated in 1589, but was forced to fight the Holy League  for nine years to secure his kingdom.
In 1593 he converted to Roman Catholicism to remove all pretext for resistance to his rule. He entered Paris amid cheers in 1594, but he had to wage war (1595 – 98) against Spain, which supported the remaining resistance to him in France. Henry signed the Edict of Nantes in 1598, ending 40 years of civil war. With the aid of his ministers, including the duke de Sully, Henry brought order and new prosperity to France.
His earlier marriage was annulled, and in 1600 he married Marie de Médicis.

In 1610 he was assassinated by a fanatical Roman Catholic.
