The National Assembly played a crucial role in the French Revolution by representing the interests of the common people, particularly the Third Estate, which comprised the majority of the population. Formed in June 1789, the National Assembly emerged after the Estates-General convened and disagreements arose over voting procedures. It sought to challenge the authority of King Louis XVI and promote democratic reforms, culminating in the adoption of the Declaration of the Rights of Man and of the Citizen. The National Assembly was instrumental in dismantling feudalism and paving the way for a more egalitarian society in France.
