Bastarnaeball

 was a ancient Unidentified land stealer tribeball in Romaniaball who lived between 200 BC and 300 AD inhabited areas north of the Romanball frontier on the Lower Danube. The Bastarnaeballs lived in the region between the Carpathian Mountains and the river Dnieper, to the north and east of ancient Daciaball. The Peuciniball occupied the region north of the Danube Delta. The earliest Graeco-Romanball historians to refer to the Bastarnaeballs imply that they spoke Celticball languages. In contrast, later historical sources imply that they spoke Germanyball languages, and could be considered Germanyballs. Like other balls who lived in the same geographical region, Graeco-Romanball writers also referred to the Bastarnaeball as a Scythianballs, but this was a general term, not a linguistic category.

Although largely sedentary, some elements may have adopted a semi-nomadic lifestyle. So far, no archaeological sites have been conclusively attributed to the Bastarnaeball. The archaeological horizons most often associated by scholars with the Bastarnaeball are the Zarubintsyball and Poienesti-Lukashevkaball cultures.

The Bastarnaeballs first came into conflict with the Romanballs during the 1st century BC when, in alliance with Daciaballs and Sarmatiansball, they unsuccessfully resisted Romanball expansion into Moesiaball and Pannoniaball. Later, they appear to have maintained friendly relations with the Romanball during the first two centuries AD. This changed c. 180, when the Bastarnaeball are recorded as participants in an invasion of Romanball clay, once again in alliance with Sarmatiansball and Daciaball elements. In the mid-3rd century, the Bastarnaeball were part of a Gothsball-led grand coalition of lower Danube tribes that repeatedly invaded the Balkanball provinces of the Romanball.

Many Bastarnaeballs were resettled within the clay of Romanballs in the late 3rd century.
