The main three causes of the French Revolution were financial problems, social inequalities, and bad leadership (Louis XVI and Marie Antoinette).
Motives of the French Revolution
The French Revolution was carried out by abolishing the monarchy, executing the king and queen (guillotine), creating the Committee of Public Safety, and initiating the Reign of Terror.
Methods of the French Revolution
At first an oligarchy was made in which riots were suppressed, but then leaders corrupted and chaos broke out. This led to a dictatorship being created and Napoleon taking over France.
Changes Made in the French Revolution
The Haitian Revolution was caused by mixed and people of colored being treated unfairly and forced to work in bad conditions to produce sugar on plantations. If they refused to work they were beaten.
Motives of the Haitian Revolution
At first mixed people asked for equality, then all slaves asked for equality. When this didn't work, they all attacked their slave owners at the same time. Slavery was abolished in France and ex-slaves joined the French to push out the British.
Methods of the Haitian Revolution
Unfornately, Toussaint L'Ouverture was unable to drive off incoming French troops (Napoleon had ordered his troops to conquer San Domingue) and save his people, so Haitians burned over 1/3 of the island to drive out the French who were coming to conquer them. This left Haiti isolated and the economy to drop and never return, yet.
