The Drevlians initially fervently opposed the Kievan Rus'. According to a number of chronicles, in the times of Kyi, Shchek and Khoryv (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.
