The French Revolution was a period of time in France when the people overthrew the monarchy and took control of the government.  

The French Revolution lasted 10 years from 1789 to 1799. It began on July 14, 1789 when revolutionaries stormed a prison called the Bastille. The revolution came to an end 1799 when a general named Napoleon overthrew the revolutionary government and established the French Consulate (with Napoleon as leader).

The French Revolution completely changed the social and political structure of France. It put an end to the French monarchy, feudalism, and took political power from the Catholic church. It brought new ideas to Europe including liberty and freedom for the commoner as well as the abolishment of slavery and the rights of women. Although the revolution ended with the rise of Napoleon, the ideas and reforms did not die. These new ideas continued to influence Europe and helped to shape many of Europe's modern-day governments.
