Aim. To consider the question of settlement of the Eastern Slavs across the left-bank area of the Dnieper River based on the analysis of “The Tale of Igor’s Campaign”. Methodology. A comparison of the toponymic information from “The Tale of Igor's Campaign” (Slovo o Polku Iegorevy) with that from various antique sources was conducted. Results. The analyzed historical records demonstrate a close correlation between Western European and Eastern-Slavic historical development in the Middle Ages. A suggestion is made that the Severy (the name of the Eastern Slavic peoples, literally ‘people from the North’), who had settled the vast lands to the East of the Dnieper, were keen to keep the reminiscences of their past. Thus, they would name their settlements using conspicuous and sacred names containing the root ‘Rome’ (Rim, in Russian). Research implications: The article generalizes the available data from ancient and Russian medieval sources about settlement of the Eastern Slavs.
