The causes of the French Revolution are complex and are still debated among historians. Following the Seven Years' War and the American Revolution, the French government was deeply in debt. It attempted to restore its financial status through unpopular taxation schemes, which were heavily regressive. Leading up to the Revolution, years of bad harvests worsened by deregulation of the grain industry and environmental problems also inflamed popular resentment of the privileges enjoyed by the aristocracy and the Catholic clergy of the established church. Some historians hold something similar to what Thomas Jefferson proclaimed: that France had "been awakened by our [American] Revolution. " Demands for change were formulated in terms of Enlightenment ideals and contributed to the convocation of the Estates General in May 1789. During the first year of the Revolution, members of the Third Estate (commoners) took control, the Bastille was attacked in July, the Declaration of the Rights of Man and of the Citizen was passed in August, and the Women's March on Versailles forced the royal court back to Paris in October. A central event of the first stage, in August 1789, was the abolition of feudalism and the old rules and privileges left over from the Ancien Régime.
