Who causes the French wars of revolution?
Help plz

The upheaval was caused by widespread discontent with the French monarchy and the poor economic policies of King Louis XVI, who met his death by guillotine, as did his wife Marie Antoinette.

Not only were the royal coffers depleted, but two decades of poor harvests, drought, cattle disease and skyrocketing bread prices had kindled unrest among peasants and the urban poor.
