The accidental death of Henry II in 1559 created a political vacuum that encouraged the rise of factions, eager to grasp power. Francis II of France, at this point only 15 years old, was weak and lacked the qualities that allowed his predecessors to impose their will on the leading noblemen at court. However, the House of Guise, having an advantage in the King's wife, Mary, Queen of Scots, who was their niece, moved quickly to exploit the situation at the expense of their rivals, the House of Montmorency. Within days of the King's accession, the English ambassador reported that "the house of Guise ruleth and doth all about the French King".
