Answer:
What is Third Estate was the pamphlet written by Abbe Sieyes in January 1789. It was in response to the finance minister Jacques Necker's invitation to writers for expressing their thought about the organization of Estates General. Abbe Sieyes argued that the third state was a nation in itself and there was no need for the other two estates of Clergymen and aristocracy. He wrote that the people needed a real representative in Estates General and the vote should be taken by heads. His ideas had an impact on the french people during the french revolution.
