Even though Duke Pavle was strongly opposed to the Germans, the kingdom was surrounded by Axis Powers, and he therefore decided to join them under reasonable conditions. In reply to a message from the American president, Franklin Roosevelt, that Yugoslavia should not approach the Germans, the duke said: “It’s easy for you big nations a long way away to tell the smaller ones what to do.” Two days later, on 27 March 1941, a military putsch took place in Belgrade, organized and paid for with 100,000 pounds in gold by the British secret services.
Once the regency had been removed from power, a new government, led by General Dušan Šimović , was formed. Already on 6 April 1941, Germany and Italy attacked the kingdom. On 10 April, in Zagreb, the Independent State of Croatia (NDH) was proclaimed, with Ante Pavelić as leader. The Germans thought that Vlatko Maček should stand as president, but he believed that the Allied forces would eventually win and therefore refused the position.
Croatia’s independence was at first met with high hopes by the majority of Croats, but when the government gave a large part of the coast to Italy, and began persecuting Serbs, Jews and Gypsies, this support suddenly vanished. The country was divided into two spheres: the south was governed by Italians, and the north by Germans.
As a reaction, the Partisan movement was founded and as the terror enforced by the Italians, Germans and the government increased, so the number of partisans increased. Even though the movement was mainly organized by Communists, members of the Croatian Peasants’ Party also participated. The leader of the outlawed Communist Party, Josip Broz, now became the organizer of the largest anti-fascist movement in occupied Europe.
In 1943, the Zemaljsko antifašističko vijeć e narodnog oslobodjenja Hrvatske (Territorial Antifascist Council for the Liberation of Croatia), or ZAVNOH, was formed. Italy capitulated on 8 September 1943, and at the following ZAVNOH assembly it was decided that both the Treaty of Rapallo from 1920 and the Treaty of Rome from 1941, through which Italy had taken possession of much of the Croatian coast, should be abolished.
Initially, the Allied forces only acknowledged the Yugoslav royal government in exile, based in London, but later the British were the first to help the partisans, having been persuaded by Winston Churchill, who even sent his son as a military agent to Tito. That was how the British established a strong military base on the island of Vis, where still today there is a British military cemetery. Vis was for some time the capital of liberated Yugoslavia and it was here, on 14 June 1944, that the first meeting between Tito and Šubašić , the representative of the Yugoslav government in exile, took place.
Since Tito was the military victor in the war, all possible agreements between the two of them were unsuccessful. At the beginning of 1945 there was a conference in Yalta in which three great leaders participated, and the well-known division of interests in a liberated Europe was agreed between Stalin and Churchill. Their interests in Yugoslavia were divided 50-50%.
Germany capitulated on 9 May 1945, bringing about the end to the Independent State of Croatia. Together with the military retreat, many pro-Ustaša civilians also tried to leave the country, frightened of possible revenge attacks. When they reached Austria, they were turned back by the British army, and regardless of whether they were soldiers or civilians, they were handed over to the partisans and killed on the field of Bleiburg.
As usual in history, when the number of war casualties comes into question, the sum of people killed varied depending on who one asks. After the Second World War the Yugoslavian government sent a report (for obtaining war reparations) to an international committee in which they stated that 1,700,000 people had been killed. But many people believe that the real number was around 1,000,000. Estimates regarding how many people died in the infamous concentration camp of Jasenovac vary from 60,000 to 700,000.
