1991 - 1998

The 1991 siege of Vukovar by JNA and Serbian forces lasted 87 days, destroying the town and killing hundreds of civilians. Vukovar was a multi-ethnic town before the war; its destruction and the subsequent ethnic cleansing devastated both Croat and Serb communities. The Vukovar Water Tower, hit by over 600 shells, was preserved as a deliberate national symbol — not a politically neutral monument. The Erdut Agreement (November 1995) established the framework for peaceful reintegration of eastern Slavonia, completed under UNTAES by 1998. Eltz Manor was substantially damaged in 1991 and restored 2008–2011. Serb returnees face a landscape where pre-war multi-ethnic cultural practices were severed by displacement; their parallel Orthodox ritual calendar (Julian Easter, slava, Vrbica) runs largely invisible alongside the Catholic/festival year.

1945 - 1990

Yugoslav socialist cultural policy institutionalized Šokci village customs as state-sponsored folklore festivals: Brodsko kolo (founded 1962), Vinkovačke jeseni (1966), and Đakovački vezovi (1967). These events selected Catholic/Šokci customs — kolo, tamburica, folk costume, bećarac — while excluding Serb Orthodox customs (slava, Vrbica/Lazarus Saturday) and Roma musical contributions. The festivals secularized ritual content, standardized local variants, and attached customs to Croatian-republic identity rather than regional or multi-ethnic frameworks. Yet they also preserved practices that might have faded with urbanization. The Spring Procession of Ljelje/Kraljice at Gorjani — a Pentecost ritual possibly pre-Christian in origin (the claim is plausible but unproven), shared with Serbian kraljice traditions — continued at the village level, later inscribed by UNESCO in 2009.

1918 - 1945

The creation of the Kingdom of Serbs, Croats, and Slovenes (1918) merged Slavonia into a South Slavic state, but the interwar period saw sharpening Croat-Serb tensions. During WWII, the Ustaše regime established the Jasenovac concentration camp complex on the Sava river — where tens of thousands of Serbs, Jews, and Roma were murdered. Independent scholars and the USHMM estimate 80,000–100,000 victims, though both higher and lower estimates serve nationalist political projects. The memorial site is physically split between Jasenovac village in Croatia and Donja Gradina across the Sava in Bosnia-Herzegovina. Jewish, Serb, and Croat WWII resistance groups have boycotted state commemorations due to government tolerance of revisionism, including the fabricated 'post-war camp' narrative in Sedlar's 2016 film.

1835 - 1918

The Illyrian Movement and Croatian national revival (from c. 1835) transformed Slavonia's cultural landscape. Bishop Josip Juraj Strossmayer commissioned Đakovo Cathedral (1866–1882), one of the largest neo-Romanesque churches in Southeast Europe. Pajo Kolarić founded the first tamburica orchestra in Osijek in 1847 — a tradition now shared as a national instrument by both Croats and Serbs. The Pejačević family, whose castle in Našice was home to pioneering composer Dora Pejačević, embodied the Croat political elite within Austria-Hungary. But the era also brought Magyarization pressures and the demographic reshuffling that would set the stage for 20th-century ethnic conflict.
