1699 - 1871

The Treaty of Karlowitz (1699) transferred Slavonia to the Habsburg Monarchy, which refortified the frontier against the Ottomans with star forts at Osijek (Tvrđa, 1693–1735), Slavonski Brod (Brod Fortress, 1715–1780), and elsewhere. These garrisons were manned by Serb and Croat grenzer families settled along the Military Frontier — a demographic legacy that shaped the region's multi-ethnic character until the 20th century. Baroque manor houses replaced Ottoman-era ruins: Eltz Manor in Vukovar (1749–1751), Prandau-Normann Castle in Valpovo (rebuilt on a medieval fortress from 1721), and the Odescalchi renovation of Ilok Castle. The Đakovo Stud Farm, established 1506, received Lipizzaner breeding stock from Lipica in the early 19th century. The Military Frontier was demilitarized in 1871, integrating its population into civil administration.

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.

1526 - 1699

The Battle of Mohács (1526) opened the Pannonian plains to Ottoman conquest. The Sanjak of Pojega, founded around 1538 with Požega as its capital, administered the territory between the Sava and Drava rivers under successive eyalets (Rumelia, Budin, Bosnia, Kanije). Ottoman tax registers record a population of Christian Vlachs alongside Muslim settlers, but above-ground Ottoman traces are faint in Slavonia today — the most tangible remnant is the former mosque in Đakovo, converted to the Church of All Saints after the Habsburg reconquest. Crucially, Ottoman rule brought the Serb Orthodox monastic tradition: Orahovica Monastery, mentioned in the late 15th century under the name Remeta, became by 1583 the seat of the Požega metropolitanate — the institutional anchor of Serb Orthodox religious life that persists to this day.

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.
