United Duchies of Jülich-Cleves-Berg
Marie had to wait until 13 May 1610 to be finally crowned Queen of France. At this time Henry IV was about to depart to fight in the War of Succession over the United Duchies of Jülich-Cleves-Berg; the coronation aimed to confer greater legitimacy on the Queen from the perspective of a possible regency which she would be called upon to provide in the absence of the King. The very next day (14 May), Henry IV was assassinated by François Ravaillac - which immediately raised suspicions of a conspiracy.
