France in the late 18th century was divided into an unequal social hierarchy consisting of the First Estate (clergy), Second Estate (nobility), and Third Estate (everyone else). King Louis XVI and Queen Marie Antoinette were disliked due to lavish spending while the Third Estate faced heavy taxes. Growing social tensions erupted in the storming of the Bastille prison in 1789 and the transfer of the royal family to Paris, marking the beginning of the French Revolution. The National Assembly established a new constitution and declared rights of citizens, but internal conflicts and threats from other European nations led to a period of turmoil known as the Reign of Terror.
