The National Constituent Assembly is a legislative body formed to draft or adopt a new constitution for a country. It typically arises during significant political changes, such as revolutions or transitions to democracy. The assembly's primary role is to represent the people's will and establish the fundamental laws that govern the nation. In many cases, the National Constituent Assembly is composed of elected representatives who gather to discuss and negotiate the principles and rights that will shape the new constitution. Historical examples include the French National Constituent Assembly of 1789, which played a crucial role in the French Revolution.
