Final answer:
The French Revolution's main cause was an economic crisis resulting from heavy taxation on the third estate and financial bankruptcy, highlighted by dire poverty among commoners and exacerbated by poor harvests.
Step-by-step explanation:
The main cause of the French Revolution was an economic crisis that was marked by a financial bankruptcy, which severely affected the third estate, consisting largely of peasants and the urban poor who were burdened with excessive taxes. The aristocracy and the church, representing the first and second estates, were nearly exempt from taxes and retained their wealth, heightening the frustrations among the common people. Poor harvests and famine further exacerbated the tension, leading to a revolutionary movement that demanded reforms, including a constitution to limit the power of the king. The main cause of the French Revolution was a combination of social, economic, and political factors. The poor economic conditions, including a financial crisis and poor harvests, left many French citizens angry and hungry. The unfair tax system, where the peasants and middle class paid the majority of taxes, while the clergy and aristocracy were exempt, further fueled the revolution. Additionally, the growing middle class, inspired by Enlightenment principles, pushed for political change and equal rights.
