The Baden Culture settled here in the mid-4th millennium B.C., arriving from the East along the loess terraces. Cohabitation of the new herding population with the older inhabitants of the area, mostly agriculturalists from the wider region, gradually led to new relationships and formed new cultures.
The earliest finds of the Vučedol Culture are mostly from the immediate neighborhood—eastern Slavonia and western Srijem. The culture arose here and took shape and flooded into the attractive locality of Vučedol. One can recognize the dominant Indo-European tradition in it.
At Vučedol sites in layers dating from the time of the Baden Culture we find toy-sized clay models of carts. These finds, togther with the remains of a wheel and an axle from the stilt-house settlement Stare Gmajne near Verd in the Ljubljana Marshes, show that the wheel was firmly fixed on the axle so that they both rotated in the cart structure. Such well-preserved finds of wood are exceptionally rare. The wheel find allows precise reconstruction, so that we know that the wheel was 70 cm wide and 5 cm thick, and the axle 120 cm in length.
