Jacques-Louis David, Oath of the Tennis Court, 1791 (Louvre Museum, Paris). In 1789, King Louis XVI (the Sun King's great-great-great-grandson) called an assembly of representatives. As a result, the National Assembly formed, made up of what was the "Third Estate." (These so-called "peasants" now included the powerful and savvy middle class.) After King Louis XVI refused to let the National Assembly convene in an official venue, they met at a tennis court instead — and volleyed new ideas about. Democracy in Europe was beginning.
