Occupied Yugoslavia in the context of "Chetniks"

The Yugoslav Partisans, officially the National Liberation Army and Partisan Detachments of Yugoslavia (often shortened as the National Liberation Army) was the communist-led anti-fascist resistance to the Axis powers (chiefly Nazi Germany) in occupied Yugoslavia during World War II. Led by Josip Broz Tito, the Partisans are considered to be Europe's most effective anti-Axis resistance movement during World War II.

Primarily a guerrilla force at its inception, the Partisans developed into a large fighting force engaging in conventional warfare later in the war, numbering around 650,000 in late 1944 and organized in four field armies and 52 divisions. The main stated objectives of the Partisans were the liberation of Yugoslav lands from occupying forces and the establishment of a communist-ruled Yugoslav state.

Jasenovac (pronounced [jasěnoʋat͡s]) was a concentration and extermination camp established in the village of the same name by the authorities of the Independent State of Croatia (NDH) in occupied Yugoslavia during World War II. The concentration camp, one of the ten largest in Europe, was established and operated by the governing Ustaše regime, Europe's only Nazi collaborationist regime that operated its own extermination camps, for Serbs, Romani, Jews, and political dissidents. It quickly grew into the third largest concentration camp in Europe.

The camp was established in August 1941, in marshland at the confluence of the Sava and Una rivers near the village of Jasenovac, and was dismantled in April 1945. It was "notorious for its barbaric practices and the large number of victims". Unlike German Nazi-run camps, Jasenovac lacked the infrastructure for mass murder on an industrial scale, such as gas chambers. Instead, it "specialized in one-on-one violence of a particularly brutal kind", and prisoners were primarily murdered with the use of knives, hammers, and axes, or shot.

The Governorate of Dalmatia (Italian: Governatorato di Dalmazia; Croatian: Guvernatorat Dalmacija) was an administrative division of the Kingdom of Italy that existed during two periods, first from 1918 to 1920 and then from 1941 to 1943. The first Governorate of Dalmatia was established following the end of World War I, given the London Pact (1915), and was disastablished following the Treaty of Rapallo. The London Pact also promised Italy part of Dalmatia (for the presence of Dalmatian Italians). However, both the peace settlement negotiations of 1919 to 1920 and the Fourteen Points of Woodrow Wilson, who advocated self-determination, took precedence, with Italy being permitted to annex only Zadar from Dalmatia, with the rest of Dalmatia being part of Yugoslavia. Enraged Italian nationalists considered the decision to be a betrayal of the promises of the London Pact, so this outcome was denounced as a "mutilated victory".

The second Governorate of Dalmatia was established following the military conquest of Yugoslavian Dalmatia by General Vittorio Ambrosio, during World War II. It had the provisional purpose of progressively importing Italian national legislation in Dalmatia in place of the previous one, thus fully integrating it into the Kingdom of Italy. It was a territory divided into three provinces of Italy during the Fascist Italy and Italian Empire epoch. It was created as an entity in April 1941 at the start of World War II in Yugoslavia, by uniting the existing province of Zara with occupied Yugoslav territory annexed by Italy after the invasion of Yugoslavia by the Axis powers and the signing of the Rome Treaties.
