The common aspect in both American and French revolution was that the civilians were fighting for equality and freedom.
Step-by-step explanation:
French protested against their own government whereas American colonists were against the home land or the parent nation. Civilians held much power in deposing the government which were not in favor of them. American revolution proved to be an inspiration to the french that a revolt against major European political power can be possible and it can be successful too.
Americans never intended to ruin the English government, they just wanted to self govern and they used defensive practices. French on the other hand were turning against the monarchical form of government and they wanted to depose the despotic monarch of France. Many American leaders who sustained during the revolution, became famous leaders such as Benjamin Franklin, John Adams, George Washington. Maximilien Robespierre and Jacques Pierre Brissot went to the guillotine while Jean-Paul Marat was stabbed to death in his bath.
At the American revolution a unique constitution which became the epitome of democracy arose. Whereas french believed on the doctrines of Rousseau and held the absolute will of people to be high which paved way for Napoleon Bonaparte to rise to power.
