Final answer:
The French Revolution of 1789 was primarily driven by injustices under the old feudal order, Enlightenment ideas challenging traditional beliefs, and social unrest fueled by poor harvests and financial crisis.
Explanation:
The fundamental cause of the French Revolution of 1789 was injustices under the old feudal order. The French society was divided into unequal classes with special privileges for the nobility and clergy, leading to heavy taxes on the common people and forced labor.
The Enlightenment also played a significant role as intellectuals challenged traditional beliefs and advocated for reason and change, inspiring a desire for reform and political change among the populace.
Poor harvests, a financial crisis, and urban discontent further fueled anger and hunger among the French population, culminating in the start of the Revolution and the quest for a more equitable society.
