In a context of civil and international war, Louis XVI was suspended and arrested at the time of the Insurrection of 10 August 1792. One month later, the absolute monarchy was abolished and the First French Republic was proclaimed on 21 September 1792. Louis was then tried by the National Convention (self-instituted as a tribunal for the occasion), found guilty of high treason, and executed by guillotine on 21 January 1793, as a desacralized French citizen under the name of "Citizen Louis Capet", in reference to Hugh Capet, the founder of the Capetian dynasty – which the revolutionaries interpreted as Louis's surname. Louis XVI was the only king of France ever to be executed, and his death brought an end to more than a thousand years of continuous French monarchy. Both of his sons died in childhood, before the Bourbon Restoration; his only child to reach adulthood, Marie Thérèse, was given over to the Austrians in exchange for French prisoners of war, eventually dying childless in 1851.
