Albert-Xavier-Émile Mathiez (French pronunciation: ​[albɛʁ ɡzavje emil matje]; 10 January 1874 – 25 February 1932) was a French historian, best known for his Marxist interpretation of the French Revolution. Mathiez emphasized class conflict. He argued that 1789 pitted the bourgeoisie against the aristocracy and then the Revolution pitted the bourgeoisie against the sans-culottes, who were a proletariat-in-the-making. Mathiez greatly influenced Georges Lefebvre and Albert Soboul in forming what came to be known as the orthodox Marxist interpretation of the Revolution. Mathiez admired Maximilien Robespierre, praised the Reign of Terror and did not extend complete sympathy to the struggle of the proletariat.
