Ustaše in the context of "Ultranationalist"

The Independent State of Croatia (Croatian: Nezavisna Država Hrvatska, NDH) was a World War II–era quasi-protectorate of Fascist Italy (1941–1943) and puppet state of Nazi Germany (1941–1945). It was established in parts of occupied Yugoslavia on 10 April 1941, after the invasion by the Axis powers. Its territory consisted mostly of modern-day Croatia and Bosnia and Herzegovina, as well as some parts of modern-day Serbia and Slovenia, but also excluded many Croat-populated areas in Dalmatia (until late 1943), Istria, and Međimurje regions (which today are part of Croatia).

During its entire existence, the NDH was governed as a one-party state by the fascist Ustaše organization. The Ustaše was led by its Poglavnik, Ante Pavelić. The regime targeted Serbs, Jews and Roma as part of a large-scale campaign of genocide, as well as anti-fascist or dissident Croats and Bosnian Muslims. According to Stanley G. Payne, "crimes in the NDH were proportionately surpassed only by Nazi Germany, the Khmer Rouge in Cambodia and several of the extremely genocidal African regimes." In the territory controlled by the NDH, between 1941 and 1945, there existed 22 concentration camps. The largest camp was Jasenovac. Two camps, Jastrebarsko and Sisak, held only children.

World War II in the Kingdom of Yugoslavia began on 6 April 1941, when the country was invaded and swiftly conquered by Axis forces and partitioned among Germany, Italy, Hungary, Bulgaria and their client regimes. Shortly after Germany attacked the USSR on 22 June 1941, the communist-led republican Yugoslav Partisans, on orders from Moscow, launched a guerrilla liberation war fighting against the Axis forces and their locally established puppet regimes, including the Axis-allied Independent State of Croatia (NDH) and the Government of National Salvation in the German-occupied territory of Serbia. This was dubbed the National Liberation War and Socialist Revolution in post-war Yugoslav communist historiography. Simultaneously, a multi-side civil war was waged between the Yugoslav communist Partisans, the Serbian royalist Chetniks, the Axis-allied Croatian Ustaše and Home Guard, Serbian Volunteer Corps and State Guard, Slovene Home Guard, as well as Nazi-allied Russian Protective Corps troops.

Both the Yugoslav Partisans and the Chetnik movement initially resisted the Axis invasion. However, after 1941, Chetniks extensively and systematically collaborated with the Italian occupation forces until the Italian capitulation, and thereon also with German and Ustaše forces. The Axis mounted a series of offensives intended to destroy the Partisans, coming close to doing so in the Battles of Neretva and Sutjeska in the spring and summer of 1943.

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.

Poglavnik (Croatian: [pǒɡlaːʋniːk]) is a Croatian word meaning 'leader' or 'guide'.

As a political title, it is strongly associated with Ante Pavelić, head of the fascist organization known as the Ustaše in 1929 and served as dictator of the Independent State of Croatia, a World War II fascist puppet state built out of parts of Axis occupied Yugoslavia by the authorities of Nazi Germany and Fascist Italy, between 1941 and 1945.

Ante Pavelić (Croatian: [ǎːnte pǎʋelit͡ɕ] ; 14 July 1889 – 28 December 1959) was a Croatian politician who founded and headed the fascist ultranationalist organization known as the Ustaše in 1929 and was dictator of the Independent State of Croatia (NDH), a fascist puppet state built out of parts of occupied Yugoslavia by the authorities of Nazi Germany and Fascist Italy, from 1941 to 1945. Pavelić and the Ustaše persecuted many racial minorities and political opponents in the NDH during the war, including Serbs, Jews, Romani, and anti-fascists, becoming one of the key figures of the genocide of Serbs, the Porajmos and the Holocaust in the NDH.

At the start of his career, Pavelić was a lawyer and a politician of the Croatian Party of Rights in the Kingdom of Yugoslavia known for his nationalist beliefs and support for an independent Croatia. By the end of the 1920s, his political activity became more radical as he called on Croats to revolt against Yugoslavia, and schemed an Italian protectorate of Croatia separate from Yugoslavia. After King Alexander I declared his 6 January Dictatorship in 1929 and banned all political parties, Pavelić went abroad and plotted with the Internal Macedonian Revolutionary Organization (IMRO) to undermine the Yugoslav state, which prompted the Yugoslav authorities to try him in absentia and sentence him to death. In the meantime, Pavelić had moved to Fascist Italy where he founded the Ustaše, a Croatian nationalist movement with the goal of creating an independent Croatia by any means, including the use of terror. Pavelić incorporated terrorist actions in the Ustaše program, such as train bombings and assassinations, staged a small uprising in Lika in 1932, culminating in the assassination of King Alexander in 1934 in conjunction with the IMRO. Pavelić was once again sentenced to death after being tried in France in absentia and, under international pressure, the Italians imprisoned him for 18 months, and largely obstructed the Ustaše in the following period.

The Jastrebarsko children's camp held Serb children who had been brought there from various areas of the Axis puppet state, the Independent State of Croatia (Croatian: Nezavisna Država Hrvatska, NDH), during World War II. The children had been captured as a result of massacres and counter-insurgency operations conducted by the genocidal Ustaše-led government, its Axis allies and other collaborators since the Axis invasion of Yugoslavia and establishment of the NDH in April 1941. The camp was located in the town of Jastrebarsko, about 37 kilometres (23 mi) southwest of the NDH capital, Zagreb, and operated from 12 July until October 1942. Camp administration was provided by nuns of the Daughters of Charity of Saint Vincent de Paul order, with Ustaše guards.

Children arrived in an emaciated and weak condition from other camps within the Ustaše camp system, with a total of 3,336 children passing through the camp. Between 449 and 1,500 children died, mainly from disease and malnutrition. A sub-camp was established in nearby Donja Reka. The Yugoslav Partisans liberated about 350 children from the main camp in August 1942. In October 1942, about 500 of the surviving children were dispersed among local families by the Catholic aid group, Caritas; in total, 1,637 boys and girls were taken in by families in Jastrebarsko, Zagreb and surrounding villages, and another 113 were relocated to Gradiška.

The Sisak concentration camp was a concentration and transit camp located in the town of Sisak, in the Axis puppet state the Independent State of Croatia (NDH), from 1941 to 1945, during World War II. It consisted of two sub-camps, Sisak I and Sisak II. The former was used to intern adults destined for forced labour in the Reich and was established in 1941, while the latter was used to detain unaccompanied Serb—and to a lesser extent, Jewish and Roma—children who had been separated from their parents over the course of the conflict. Sisak I was operated by the Germans, whereas Sisak II was administered by the Ustaše, with some German gendarmes guarding its perimeter. The latter became operational in July–August 1942, receiving a group of children who had previously been detained at Mlaka.

Living conditions at the children's camp were poor, leading to a high mortality rate. According to survivors, some children were killed by being given poisoned milk or gruel laced with caustic soda. On other occasions, camp commander Antun Najžer administered children with lethal injections. Thousands of children were saved from the camp as a result of rescue efforts spearheaded by the humanitarian Diana Budisavljević and the local communist underground. Sisak II was dissolved in January 1943. The exact number of children who perished there is unknown, but estimates range from 1,160 to 1,600, largely as a result of starvation, thirst, typhus and neglect. In April 1944, the Germans ceded control of Sisak I to the Ustaše. It was shut down in January 1945 and its remaining inmates were dispatched to Jasenovac.

The Genocide of Serbs in the Independent State of Croatia (Serbo-Croatian: Genocid nad Srbima u Nezavisnoj Državi Hrvatskoj / Геноцид над Србима у Независној Држави Хрватској) was the systematic persecution and extermination of Serbs committed during World War II by the fascist Ustaše regime in the Nazi German puppet state known as the Independent State of Croatia (Serbo-Croatian: Nezavisna Država Hrvatska / Независна Држава Хрватска, NDH) between 1941 and 1945. It was carried out through executions in death camps, as well as through mass murder, ethnic cleansing, deportations, forced conversions, and war rape. This genocide was simultaneously carried out with the Holocaust in the NDH as well as the genocide of Roma, by combining Nazi racial policies with the ultimate goal of creating an ethnically pure Greater Croatia.

The ideological foundation of the Ustaše movement reaches back to the 19th century. Several Croatian nationalists and intellectuals established theories about Serbs as an inferior race. The World War I legacy, as well as the opposition of a group of nationalists to the unification into a common state of South Slavs, influenced ethnic tensions in the newly formed Kingdom of Serbs, Croats and Slovenes (since 1929 Kingdom of Yugoslavia). The 6 January Dictatorship and the later anti-Croat policies of the Serb-dominated Yugoslav government in the 1920s and 1930s fueled the rise of nationalist and far-right movements. This culminated in the rise of the Ustaše, an ultranationalist, terrorist organization, founded by Ante Pavelić. The movement was financially and ideologically supported by Benito Mussolini, and it was also involved in the assassination of King Alexander I.
