Croatian socialism was the name for the foundations of the social-economic ideology that the Ustaša movement in the Independent State of Croatia began to build during the Second World War. The Pavelić regime produced extensive literature about the organization, economic and political that the new Croatian state would follow, concluding to adopt a purely Croatian 'socialism', strongly inspired by Nazism, based on class collaboration for the common benefit and ethnic nationalism. The authorities argued that the so-called 'Croatian socialism' was the appropriate model for the nature of the Croatian people, which throughout its history had been characterized by its community, solidarity and cooperative spirit and by its worker-peasant structure. 'Croatian socialism' was theoretically elaborated in the works of philosophers Stjepan Zimmermann and Čedomil Veljačić, sociologist and ethnologist Mirko Kus Nikolajev, as well as the syndicalist Aleksandar Seitz.[1] [2]
