Yugoslavia was established after World War I as the Serbian-Croatian-Slovenian Kingdom. Although the name of the newly-founded state bore the names of Croatians and Slovenians, the administration until World War II remained primarily under Serbian rule. Even the change of the country's name in 1929 to Yugoslavia (the Land of the Southern Slavs) did not mean that Serbian rule had ended. The country was invaded by the Axis powers in World War II. During those years, the pro-Axis Ustasa Croatian state was formed in Bosnia-Herzegovina and Croatia.
