History of Sardinia
In the Early Middle Ages, through barbarian movements, the waning of the Byzantine Empire influence in the western Mediterranean and the Saracen raids, the island fell out of the sphere of influence of any higher government. This led to the birth of four kingdoms called "Judicates" (Latin: "Judicati"; Sardinian: "Judicados") in the 8th through 10th centuries. Falling under papal influence, Sardinia became the focus of the rivalry of Genoa and Pisa, the Judicates and the Crown of Aragon, which eventually subsumed the island as the Kingdom of Sardinia in 1324. The Kingdom was to last until 1718, when it was ceded to the Piedmontese House of Savoy; later, in 1861, it would thus become the Kingdom of Italy and finally in 1946 the Italian Republic.
Sazan Island
Italy in turn occupied it on 30 October 1914, and established a military commander on the island, which is called Saseno in Italian. This was later ratified on 26 April 1915 by the secret Treaty of London. After World War I, Albania formally ceded the island to Italy on 2 September 1920 as part of the Albano-Italian protocol. The island was part of Italy from 1920 until World War II, it was administratively part of Lagosta, inside the Italian Province of Zara. In those years the Italian authorities built a lighthouse and some naval fortifications, and populated the island with a few families of fishermen relocated from Apulia. The island was united to the Italian Governatorate of Dalmatia in 1941 during World War II and ceded to Albania on 10 February 1947, under the postwar peace treaty with Italy.
