Following World War I, Bosnia and Herzegovina joined the South Slav [[Kingdom of Yugoslavia|Kingdom of Serbs, Croats and Slovenes]] (soon renamed Yugoslavia). Political life in Bosnia and Herzegovina at this time was marked by two major trends: social and economic unrest over [[Distribution (economics)|property redistribution]] and the formation of several political parties that frequently changed coalitions and alliances with parties in other Yugoslav regions.<ref name="Riedlmayer"/>

The dominant ideological conflict of the Yugoslav state, between Croatian regionalism and Serbian centralization, was approached differently by Bosnia and Herzegovina's major [[ethnic group]]s and was dependent on the overall political atmosphere.{{sfn|Malcolm|2002}} The political reforms brought about in the newly established Yugoslav kingdom saw few benefits for the Bosnian Muslims; according to the 1910 final census of land ownership and population according to religious affiliation conducted in Austria-Hungary, Muslims owned 91.1%, Orthodox Serbs owned 6.0%, Croat Catholics owned 2.6% and others, 0.3% of the property. Following the reforms, Bosnian Muslims were dispossessed of a total of 1,175,305 hectares of agricultural and forest land.<ref>{{cite web|author=Danijela Nadj|url=http://www.hic.hr/books/seeurope/010e-semiz.htm|title=An International Symposium "Southeastern Europe 1918–1995"|publisher=Hic.hr|access-date=14 June 2006|archive-url=https://web.archive.org/web/20060822164923/http://www.hic.hr/books/seeurope/010e-semiz.htm|archive-date=22 August 2006|url-status=live}}</ref>

Although the initial split of the country into 33 [[oblast]]s erased the presence of traditional geographic entities from the map, the efforts of Bosnian politicians, such as [[Mehmed Spaho]], ensured the six oblasts carved up from Bosnia and Herzegovina corresponded to the six sanjaks from Ottoman times and, thus, matched the country's traditional boundary as a whole.{{sfn|Malcolm|2002}}

The establishment of the Kingdom of Yugoslavia in 1929, however, brought the redrawing of administrative regions into [[Kingdom of Yugoslavia#Subdivisions|banates]] or ''[[Banovina (region)|banovinas]]'' that purposely avoided all historical and ethnic lines, removing any trace of a Bosnian entity.{{sfn|Malcolm|2002}} Serbo-Croat tensions over the structuring of the Yugoslav state continued, with the concept of a separate Bosnian division receiving little or no consideration.

The [[Cvetković–Maček Agreement|Cvetković-Maček Agreement]] that created the [[Banovina of Croatia|Croatian banate]] in 1939 encouraged what was essentially a [[partition of Bosnia and Herzegovina]] between Croatia and Serbia.<ref name="Imamović, Mustafa 1996"/> However the rising threat of [[Adolf Hitler]]'s [[Nazi Germany]] forced Yugoslav politicians to shift their attention. Following a period that saw attempts at appeasement, the signing of the [[Tripartite Pact|Tripartite Treaty]], and a [[Yugoslav coup d'état|coup d'état]], Yugoslavia was finally invaded by Germany on 6 April 1941.{{sfn|Malcolm|2002}}
