From the Kaisers, the third Capetian king of France was christened Henri, a form always frequent there, though only four times on the throne.  Its popularity culminated during the religious wars, when Henri de Valois, Henri de Bourbon, and Henri de Guise were fighting the war of the three Henris; but in spite of the French love and pride in le grand monarque, the growing devotion to St. Louis, from whom the Bourbon rights to the throne were derived, set Henri aside from being the royal name, until the birth of him whom legitimists still call Henri V.
