How did king Louis XIX rule France?

Answer 1

It began the slow but steady movement from a wealthy European Nation to a debtor Nation. This position was advanced under Louis XV and was made even worse as a result of the Seven Years Wars and the French aid to the United States during the American Revolution under the leadership of King Louis XVI. By 1789 the National debt had developed into a crisis which became the French Revolution.

It should be noted that France became a patron of the Arts and of Architecture during his reign, and remains a leader in that cultural arena even today.

Answer 2

Louis XIX only ruled over France for 20 minutes and most of that time was spent deciding whether he would abdicate like his father in the French Revolution of 1830 (which he did do) or would try to rule in his own name. Since Louis XIX was only in power for 20 minutes and his only act in office was to abdicate, it would be improper to say what the extent of his powers or style of rulership was.
