The National Assembly made several important decisions that changed the balance of power in France: 1. They declared the Rights of Man, establishing equality and freedoms of speech and religion but excluding women. This benefited the lower classes. 2. The Assembly seized land from the Catholic Church and made it a state institution rather than politically independent, gaining wealth while reducing the Church's power. 3. A limited constitutional monarchy was created to curb the King's authority and empower the Legislative Assembly. 4. War with Austria and Prussia ended badly for France and led to chaos, causing the Assembly to depose Louis XVI and form the radical National Convention to rule.
