Jean-Paul Marat (French: [??~p?l ma?a]; 24 May 1743 – 13 July 1793) was a French political theorist, physician, and scientist.
He was a journalist and politician during the French Revolution.
He was a vigorous defender of the sans-culottes and seen as a radical voice.
He 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.
His journalism was renowned for its fierce tone, advocacy of basic human rights for the poorest members of society, and uncompromising stance toward the new leaders and institutions of the revolution.
Responsibility for the September Massacres has been attributed to him, but the collective mentality that made them possible resulted from circumstances and not from the will of any particular individual.
Marat was assassinated by Charlotte Corday, a Girondin sympathizer, while taking a medicinal bath for his debilitating skin condition.
Corday was executed four days later for his assassination, on 17 July 1793.
In death, Marat became an icon to the Jacobins as a revolutionary martyr.
He is portrayed in Jacques-Louis David's famous painting, The Death of Marat.
