Jean-Paul Marat (French: [ʒɑ̃pɔl maʁa]; born Mara; 24 May 1743 – 13 July 1793) was a French political theorist, physician, and scientist. A journalist and politician during the French Revolution, he was a vigorous defender of the sans-culottes, a radical voice, and published his views in pamphlets, placards and newspapers. His periodical L'Ami du peuple (Friend of the People) made him an unofficial link with the radical Jacobin group that came to power after June 1793.
