Conflict with the Protestant movement prompted the Amboise conspiracy, in which the Huguenots and the Bourbons plotted to violently overthrow the power of the House of Guise. The Guise family brutally put down the conspiracy. Near the end of the year, the Prince of Condé was in their hands, destined for execution for treason, when the death of the king, Francis II, prevented the fulfillment of their plans. After King Francis' death they opposed the more tolerant policy of the Regent, Catherine de' Medici, and the actions of the duke at the Massacre of Wassy were the immediate provoking incident for the French Wars of Religion.
