On 21 January 1793, Louis XVI was guillotined, which caused political turmoil. From January to May, Marat fought bitterly with the Girondins, whom he believed to be covert enemies of republicanism. Marat's hatred of the Girondins became increasingly heated which led him to call for the use of violent tactics against them. The Girondins fought back and demanded that Marat be tried before the Revolutionary Tribunal. After trying to avoid arrest for several days, Marat was finally imprisoned. On 24 April, he was brought before the Tribunal on the charges that he had printed in his paper statements calling for widespread murder as well as the suspension of the Convention. Marat decisively defended his actions, stating that he had no evil intentions directed against the Convention. Marat was acquitted of all charges to the riotous celebrations of his supporters.
