Who made up the bulk of the third estate?

The bulk of the Third Estate in pre-revolutionary France was composed of commoners, which included peasants, urban workers, and the bourgeoisie (middle class). Peasants made up the largest group, engaging in agriculture and struggling under heavy taxation and feudal obligations. The bourgeoisie, which included merchants, professionals, and artisans, played a significant role in advocating for social and political reforms. This diverse group had varying interests but united in their demand for greater representation and rights, ultimately leading to the French Revolution.
