Representatives from the clergy and the nobility comprised the Estates-General.
Explanation:
The Estates-General in the France of the Old Regime were assemblies convened by the King in an exceptional manner and attended by representatives of each estate: the clergy (first state), the nobility (second state) and the representatives of the people (Third state). They were created in 1302 by Philip IV of France, the Beautiful, after Pope Boniface VIII summoned King Philip IV and the French clergy to a synod to be held in Rome, on November 1, 1302, to define the relationship between temporal power and the Church; and also to judge the king, under the accusation of unprecedented abuses against the church, for which King Philip IV responded immediately.
