Estate. The total number of nobles in the three Estates was about 400. Noble representatives of the Third Estate were among the most passionate revolutionaries in attendance, including Jean Joseph Mounier and the comte de Mirabeau. Some clergy were also elected as Third Estate delegates, most notably the abbé Sieyès. Despite their status as elected representatives of the Third Estate, many of these nobles were executed by guillotine during the Terror.
