ENThe name Sudovia (Sudovians) was mentioned in the written sources for the first time in the 1st-2nd century. It is possible to find it in the famous ‘Geography’ of Claudius Ptolemaeus. Sudovians were called Yotvingians in the Polish and Russian sources. The oldest notes come from the 10th century (The Primary Chronicle of Nestor). In the oldest Polish sources their northern-east neighbours are called Podlasianie (the region Podlachia, Podlesia - Polexa). In the Lithuanian sources some parts of Yotvingia are named Dainava. The article describes the exact area inhabited by Yotvingian tribes. [From the publication]
