The Drevlians, Derevlians or Derevlianians were a tribe of East Slavs between the 6th and the 10th centuries, which inhabited the territories of Polesia and right-bank Ukraine, west of the eastern Polans and along the lower reaches of the rivers Teteriv, Uzh, Ubort, and Stsviha. To the west, the Drevlians' territories reached the Sluch River, where the Volhynians and Buzhans lived. To the north, the Drevlians' neighbors were the Dregoviches.
