Final answer:
The economic crisis was a significant cause of the French Revolution, as it led to unrest and rioting due to the regime's inability to provide relief to the peasants and urban poor.
Step-by-step explanation:
The French Revolution had multiple causes, but one cause that is often considered more important than the others is the economic crisis. In the 1770s, poor harvests and the near-bankruptcy of the French Crown left many peasants and urban poor on the brink of starvation. The regime's inability to provide relief led to unrest and rioting, creating a volatile environment that ultimately contributed to the revolution.
