The French Revolution was influenced by Enlightenment thinkers who challenged the divine right of kings. The social structure in France was unequal, with the poor paying most taxes. A growing middle class demanded more political power. France faced an ongoing financial crisis due to massive war debts and excessive spending by Louis XVI and Marie Antoinette, whose weak leadership and rumors of corruption further upset the public. Famine and poor harvests exacerbated economic problems and unrest.
