Since French Revolution singified the new phase of French or European history, the despotism declined and the republican regime uprose. During the Revolution, King Louis XVI was beheaded and regarded as a foolish and incompetent king to cause the wane of dynasty the Bourbons, and severely critized by the historians. In fact, King Louis XVI who was calm and quiet and loved reading and simple lifestyle ruled his country with love and concern. However, he, a victim of misfortune and fate since childhood, was enthroned at the age of twenty years old after the sudden death of his grandfather, King Louis XV. The political instability and social disorder caused the deterioration and downfall of the kingdom and the demise of Louis XVI, who was called Le Roi-martyr by the historians.
