Second French War of Religion
The leader of the Huguenots, Prince Louis of Condé, feared that the young king, Charles IX, wanted to persecute the Huguenots.  To prevent this, Condé and about 1,500 of his supporters attempted, on September 25, 1567, to kidnap the King at Meaux.  This incident, known as the "Surprise of Meaux", led directly to the start of the Second War of Religion.  The King escaped Condé's trap and fled into the city of Paris.
