Lefkada, however, did not become officially Venetian until 1718, with the signature of the Treaty of Passarowitz. Dissolution of the Republic and aftermath Napoleon Bonaparte declared war against Venice on 3 May 1797. The signing of the Treaty of Campo Formio, on 17 October 1797, marked the dissolution of the Republic of Venice and the sharing of its territories between France and Austria. The lands of the up to the River Adige, the city itself and the possessions of the Balkan peninsula of Istria and Dalmatia were yielded to Austria.
