Deputies of the French Third Estate take the Tennis Court Oath.

The Estates General of 1789 was a general assembly representing the French estates of the realm: the clergy (First Estate), the nobility (Second Estate), and the commoners (Third Estate). It was the last of the Estates General of the Kingdom of France. Summoned by King Louis XVI, the Estates General of 1789 ended when the Third Estate formed the National Assembly and, against the wishes of the King, invited the other two estates to join. This signaled the outbreak of the French Revolution.

A legislator (also known as a deputy or lawmaker) is a person who writes and passes laws, especially someone who is a member of a legislature. Legislators are often elected by the people of the state. Legislatures may be supra-national (for example, the European Parliament), national (for example, the United States Congress), regional (for example, the National Assembly for Wales), or local (for example, local authorities).
