Final answer:
The changes during the French Revolution include the Reign of Terror, social and religious reforms, and the rise of nationalism.
Step-by-step explanation:
The French Revolution brought about significant changes in France. One major aspect was the Reign of Terror, which was a period of extreme violence and repression. During this time, the revolutionary government imprisoned and executed thousands of people, including King Louis XVI and Marie Antoinette. Additionally, the revolution also brought about social and religious reforms. The government introduced the Declaration of Rights of Man and of the Citizen, which proclaimed equal rights for all male citizens, including the right to hold public office and freedom of religion. They also dismantled Catholicism and replaced it with a new philosophy known as the Cult of the Supreme Being. Lastly, the French Revolution played a crucial role in the rise of nationalism. The concept of a nation became central to the revolutionaries' ideals, and they called the whole 'nation' to arms to defend the fatherland. This idea of national identity influenced subsequent nationalistic movements around the world.
