Yugoslavia was initially established as a kingdom of Serbs, Slovenes, and which other group?

Yugoslavia was initially established in 1918 as the Kingdom of Serbs, Croats, and Slovenes. The inclusion of Croats alongside Serbs and Slovenes reflects the national identity and aspirations of these three groups during the post-World War I period. The formation was largely influenced by the desire for self-determination and unity among South Slavic peoples against the backdrop of the declining Austro-Hungarian Empire.

Croats were a significant ethnic group within the newly formed kingdom, representing a key part of the federation that aimed to unite the South Slavic population. This historical context is essential in understanding the dynamics of ethnic identities and nation-building in the region.

While Bosnians, Turks, and Hungarians were relevant in the broader historical and cultural context, they were either not part of the initial establishment of Yugoslavia or were represented differently in the subsequent changes and configurations of the nation's boundaries and governance. Therefore, the correct answer emphasizes the foundational ethnic groups that participated in the initial establishment of the Yugoslav state.
