Border Problems: Changes in the Borderline of Drava Banovina and Sava Banovina/Banovina of Croatia 1929–1941

This article examines the formation of the internal borders of the Kingdom of Yugoslavia and their lasting impact on the contemporary Croatian–Slovenian border region. The banovinas – the largest administrative units established during this period – serve as the primary example. When determining their borders in 1929 and 1931, the royal dictatorship allegedly applied a range of geographic, transportation, and economic criteria. The establishment of the banovina boundaries in 1929 resulted in the transfer of certain settlements from one cultural–historical and administrative context to another, prompting varied local responses. It was only after the creation of the Banovina ofCroatia in 1939 that public discussion emerged regarding the preferred administrative affiliation of individual municipalities and settlements.
