of Split and the Oblast of Dubrovnik. In 1929, the Littoral Banovina, a province of the Kingdom of Yugoslavia, was formed. Its capital was Split, and it included most of Dalmatia and parts of present-day Bosnia and Herzegovina. The southern parts of Dalmatia were in Zeta Banovina, from the Bay of Kotor to Pelješac peninsula including Dubrovnik. In 1939, Littoral Banovina was joined with Sava Banovina (and with smaller parts of other banovinas) to form a new province named the Banovina of Croatia. The same year, the ethnic Croatian areas of the Zeta Banovina from the Bay of Kotor to Pelješac, including Dubrovnik, were merged with a new Banovina of Croatia. During World War II, in 1941, Nazi Germany, Fascist Italy, Hungary, and Bulgaria occupied Yugoslavia, redrawing their borders to include former parts of the Yugoslavian state. A new Nazi puppet state, the Independent State of Croatia (NDH), was created. With the Treaties of Rome, the NDH agreed to cede to Italy Dalmatian territory, creating the Governatorate of Dalmatia, from north of Zadar to south of Split, with inland areas, plus nearly all the Adriatic islands and Gorski Kotar. Italy then annexed these territories, while all the remainder of southern Croatia, including the entire coast, were placed under Italian occupation. Italy also appointed an Italian, Prince Aimone, Duke of Aosta, as king of Croatia. Italy proceeded to Italianize the annexed areas of Dalmatia. Place names were Italianized, and Italian was made the official language in all schools, churches and government administration. All Croatian cultural societies were banned, while Italians took control of all key mineral, industrial and business establishments. Italian policies prompted resistance by Dalmatians, many joined the Partisans. This led to further Italian repressive measures - shooting of civilian hostages, burning of villages, confiscation of properties. Italians took many civilians to concentration camps - altogether, some 80,000 Dalmatians, 12% of the population, passed through Italian concentration camps. Many Croats moved from the Italian-occupied area and took refuge in the satellite state of Croatia, which became the battleground for a guerrilla war between the Axis and the Yugoslav Partisans. Following the surrender of Italy in 1943, much of Italian-controlled Dalmatia was liberated by the Partisans, then taken over by German forces in a brutal campaign, who then returned control to the puppet Independent State of Croatia. Vis Island remained in Partisan hands, while Zadar, Rijeka, Istria, Cres, Lošinj, Lastovo and
