The American Revolution began as a response to heavy British taxes imposed on the American colonies without colonial representation in Parliament. This led to protests like the Boston Tea Party and eventually the Declaration of Independence in 1776. The Revolutionary War lasted from 1775 to 1783, ending in an American victory.
The French Revolution began due to financial problems in France coupled with resentment of the extravagant monarchy and Marie Antoinette. This led to the storming of the Bastille and the formation of a National Assembly. The revolution then grew more radical, becoming a republic that engaged in war with other European powers and the Reign of Terror under Robespierre. Napoleon later rose to power from the chaos but was eventually defeated
