The Habsburg Monarchy had annexed the lands of Dalmatia after the Napoleonic War of the First Coalition: when Napoleon Bonaparte launched his Italian Campaign into the Habsburg duchies of Milan and Mantua in 1796, culminating in the Siege of Mantua, he compelled Emperor Francis II to make peace. In 1797 the Treaty of Campo Formio was signed, whereby the Habsburg emperor renounced possession of the Austrian Netherlands and officially recognized the independence of the Italian Cisalpine Republic. In turn, Napoleon ceded to him the possessions of the Republic of Venice, including the Dalmatian coast (Venetian Dalmatia) and the Bay of Kotor (Venetian Albania). "La Serenissima" had sided with Austria in order to defend her "Domini di Terraferma" and was occupied by French troops on 14 May 1797. The treaty ended the centuries-long history of the Venetian Republic.
