The Drevlians (Russian: Древля́не, translit. Drevlyane, Ukrainian: Древляни, translit. Drevliany) were a tribe of Early East Slavs between the 6th and the 10th century, 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 Stviga. To the west, the Drevlians' territories reached the Sluch River, where the Volynians (related to the territory of Volynia) and Buzhans (related to the name of Southern Bug river) lived. To the north, the Drevlians' neighbors were the Dregovichs.
Their name is derived from Slavic drevo/древо or derevo/дерево, meaning "wood" and "tree", because they lived in the forests. Their name may be rendered "the dwellers in the forest". Nestor the Chronicler (1056–1114) mentioned that those Slavs who settled in open fields had been called Polyani, and those in forest areas Drevlyani.
The Drevlians left many archaeological traces, such as agricultural settlements with semi-dugouts (or earth-houses), moundless burial grounds and barrows, fortified towns like Vruchiy (present-day Ovruch), Gorodsk, site of an ancient settlement near Malyn (supposedly, a residence of the Drevlian prince Mal) and others. The principal city of the Drevlians was Iskorosten (today's Korosten), where one can still see a group of compact ancient settlements. After the Kievan Rus' conquered the Drevlians, Iskorosten was burned to the ground and the capital transferred to Ovruch. By the end of the first millennium, the Drevlians already had well-developed farming and handicrafts.
The Drevlians initially fervently opposed the Kievan Rus. According to a number of chronicles, in the times of Kyi, Schek and Khoriv (supposedly, founders of Kiev) the Drevlians had their own princely rule and were frequently at war with the Polyani. In 883, Prince Oleg of Novgorod made the Drevlians pay tribute to Kiev. In 907, the Drevlians took part in the Kievan military campaign against the Eastern Roman Empire.
After Oleg's death in 912 the Drevlians stopped paying tribute. The Varangian warlord Sveneld made them pay tribute to himself. Oleg's successor Igor attempted to levy the tribute after Sveneld, but the Drevlians revolted and killed him in 945. Igor's widow Olga avenged her husband's death in an extremely harsh manner, killing Drevlian ambassadors and nobility, burning their capital of Iskorosten to the ground and leveling other towns. After having subjugated the Drevlians, Olga transformed their territories into a Kievan appanage with the center in Vruchiy.
