He was born in Switzerland and became a French Revolutionary.
In September 1789, he launched the newspaper that brought him fame: L’Ami du people (The Friend of the People).
His journalism was renowned for its fiery character and uncompromising stance toward ‘enemies of the revolution’ and basic reforms for the poorest members of society.
His newspaper was little more than an extended editorial page filled with intemperate calls for violence against traitors and for an elected dictator to serve for a limited time to save the Revolution.
His reputation as a blood thirsty writer who called for the executions of counter-revolutionaries made many suspects that he was behind the September Massacres. In 1792, Marat was elected to the National Convention.
Marat suffered from the chronic skin condition psoriasis and spent much time in his bath with a vinegar soaked bandage.
This was where Charlotte Corday found him. As soon as they were alone together she stabbed him, cutting his carotid artery.
