 Many immigrants arrived from Liguria and the Piedmont in Italy.By the end of the 18th century, Marseille had a population of 120,000 people, making it the third largest city in France.Though most of Provence, with the exception of Marseille, Aix and Avignon, was rural, conservative and largely royalist, it did produce some memorable figures in the French Revolution; Honoré Gabriel Riqueti, comte de Mirabeau from Aix, who tried to moderate the Revolution, and turn France into a constitutional monarchy like England; the Marquis de Sade from Lacoste in the Luberon, who was a Deputy from the far left in the National Assembly; Charles Barbaroux from Marseille, who sent a battalion of volunteers to Paris to fight in the French Revolutionary Army; and Emmanuel-Joseph Sieyès (1748–1836), an abbé, essayist and political leader, who was one of the chief theorists of the French Revolution, French Consulate, and First French Empire, and who, in 1799, was the instigator of the coup d'état of 18 Brumaire, which brought Napoleon to power.
