By 3rd century BC, the Proto-Baltic tribes inhabiting forest of eastern Europe already divided themselves into West and East Balts. There were already significant cultural differences between the two. The western ones came in contact with more civilized people of Europe, settled and begun excavating amber, the Gold of Baltic. Combined, this gave them civilization boost and set them apart from their eastern kindred. The East Balts, it is believed, remained semi-nomadic, with rare, scattered settlements on hills. Mixed with Finno-Ugric tribes of the north, they traded textiles and products of forest with Scythians and Sarmatians. Even when roman traders arrive in these lands 300 years later, they note a difference between civilized Austjōs (Aestii), living on the coast, and nomadic Fennōs (Finns/Saami), living in the forest.

In the deep forests of north-eastern Europe, life was hard for semi-nomadic tribes of East Balts. Small, scattered settlements did not form any states or nations, and they could not field regular armies. In need, packs of hunters known as Medjīnīkōs could gather to defend their households, armed simply with their bows and spears, they cannot stand long before organized enemy army.
