The Congress of Vienna
The Congress of Vienna established the political order in Italy that lasted until unification between 1859 and 1870. According to the Final Act of the congress, Francis I of Austria also became king of Lombardy-Venetia, which was incorporated into the Habsburg state. The former episcopal principality of Trento was formally annexed to Austria. King Victor Emmanuel I of Savoy recovered his territories (Nice, Savoy, and Piedmont) and acquired the Ligurian coast, including Genoa. The duchy of Parma was granted to Marie-Louise of Habsburg, the daughter of Francis I and Napoleon’s second wife. At her death the duchy was to revert to the Bourbon-Parma family, which was also temporarily placed in charge of the duchy of Lucca. The Habsburg-Este family returned to Modena and inherited the duchy of Massa in 1825. Also in Tuscany, the Habsburg-Lorraine family added the State of the Garrisons to its former domains and was given claim to Lucca, which the Bourbon-Parma family was to relinquish in 1847. The pope recovered his temporal domain in central Italy. Ferdinand IV of Naples reassumed control of his former realm under the new title of Ferdinand I, King of the Two Sicilies.
