World War II and the Independent State of Croatia (NDH)

 World War II was a defining moment in world history, marked by the rise and fall of nations, ideologies, and political entities. One such entity that emerged during this period was the Independent State of Croatia (Nezavisna Država Hrvatska, NDH), a puppet state established by the Axis powers, particularly Nazi Germany and Fascist Italy, following the invasion and dismemberment of the Kingdom of Yugoslavia in April 1941. The NDH, under the leadership of the Ustaša movement, led by Ante Pavelić, played a significant role in the war, marked by collaboration, extreme nationalism, and crimes against humanity.

Before the establishment of the NDH, Croatia was part of the Kingdom of Yugoslavia, a multi-ethnic state formed after World War I. However, tensions between Croats and Serbs were prevalent, as many Croats resented Serbian dominance in the centralized Yugoslav government. The Ustaša, a radical Croatian nationalist and fascist organization founded in the 1930s, sought Croatian independence through violent means. Their opportunity arose when the Axis powers invaded Yugoslavia in April 1941, swiftly defeating the Yugoslav army. Shortly after, on April 10, 1941, Slavko Kvaternik, a prominent Ustaša leader, declared the establishment of the Independent State of Croatia.

The NDH encompassed modern-day Croatia and Bosnia and Herzegovina, as well as parts of Serbia. However, its sovereignty was limited, as it heavily depended on its Axis sponsors. Italy and Germany divided influence over the NDH, with Italy controlling Dalmatian coastal areas and Germany focusing on economic and military exploitation. Pavelić’s government aligned itself ideologically with the fascist regimes of Hitler and Mussolini, adopting similar policies, including racial laws and totalitarian governance.

One of the most notorious aspects of the NDH was its brutal persecution of ethnic and political groups deemed undesirable. The Ustaša regime launched a campaign of terror primarily targeting Serbs, Jews, and Roma, as well as anti-fascist Croats and communists. The NDH established concentration camps, the most infamous being Jasenovac, where tens of thousands of people were executed, subjected to forced labor, or died from inhumane conditions. The Ustaša implemented a policy of forced conversions of Serbs to Catholicism, while others faced expulsion or extermination. The genocide carried out in the NDH remains one of the darkest chapters of World War II.

Despite initial Ustaša collaboration with the Axis, resistance movements quickly emerged. The Communist-led Partisan resistance, led by Josip Broz Tito, gained momentum, attracting individuals from various ethnic groups, including Croats, Serbs, and others who opposed Axis rule. The Partisans waged a relentless guerrilla campaign against Axis forces and NDH authorities, gaining the support of the Allied powers as the war progressed. By 1943, after Italy’s surrender, and with increasing pressure from the Soviet Union and the Western Allies, the Axis position in the Balkans weakened. The Partisans, with growing support, launched large-scale offensives against NDH forces and their German allies.

By late 1944 and early 1945, as the Third Reich neared collapse, the NDH government attempted to consolidate its power but faced mounting resistance from the Partisans. In May 1945, as the Partisans entered Zagreb, the Ustaša leadership, along with many NDH military personnel and civilians, attempted to flee towards Austria, hoping to surrender to the Western Allies rather than the communists. However, many were captured and executed in what became known as the Bleiburg repatriations and the subsequent death marches.

With the defeat of the NDH, Yugoslavia was reestablished under Tito’s communist leadership, and Croatia became a constituent republic within the Socialist Federal Republic of Yugoslavia. The legacy of the NDH remains controversial, with debates over its historical interpretation, especially regarding its crimes and the role of the Ustaša. While some nationalist groups have att
