According to archaeological research, during the 970s the [[Sandomierz]] region and the [[Przemyśl]] area inhabited by the [[Lendians]] became incorporated into the Polish state.<ref>''Historia Polski średniowiecze'', p. 35.</ref> None of it is certain for the lack of written sources. It is possible that especially the Przemyśl area, also inhabited the [[White Croats]], belonged at that time to Bohemia, which supposedly extended up to the [[Bug River]] and [[Styr River]].<ref>The limits were described in the document issued by the bishop of Prague to [[Henry IV, Holy Roman Emperor]]. This document is preserved in the Chronicles of [[Cosmas of Prague]] and is considered a reliable copy; from G. Labuda ''Mieszko I'' pp. 148–151.</ref> The [[Primary Chronicle]] states that in 981 [[Vladimir I of Kiev|Vladimir]] of the [[Rurik Dynasty]] "went towards the Lachy and took their towns: Przemyśl, [[Czermno, Lublin Voivodeship|Czerwień]] and other strongholds (...)". The exact interpretation of this passage is uncertain, because the [[Rus' (people)|Ruthenian]] word "Lachy" meant both the Poles in general and the southeastern Lendians.<ref>G. Labuda, ''Mieszko I'', pp. 160, 174.</ref> Mieszko's conquest of Sandomierz could also have taken place later, together with the takeover of the [[Vistulans]] (western and central [[Lesser Poland]]).<ref>G. Labuda, ''Mieszko I'', cap. VII.4.</ref> However, Widukind in the 10th century mentions Mieszko ruled over the ''Sclavi'' tribe of ''Licicaviki'', which is identified with the Lendians.<ref name="Hensel1960">{{cite book|last=Hensel|first=Witold|author-link=Witold Hensel|title=The Beginnings of the Polish State|url=https://books.google.com/books?id=iJNHAAAAIAAJ|year=1960|publisher=Polonia Publishing House|page=47}}</ref><ref name="Jenkins1962">{{cite book|last=Jenkins|first=Romilly James Heald|author-link=Romilly Jenkins|title=Constantine Porphyrogenitus, De Adminstrando Imperio: Volume 2, Commentary|url=https://books.google.com/books?id=96ybRW9sLA4C|year=1962|publisher=Athlone Press|pages=139, 216}}</ref><ref name="Łowmiański1976">{{cite journal|last=Łowmiański|first=Henryk|author-link=Henryk Łowmiański|year=1976|title=Problematyka początków państwa polskiego w nowszych badaniach historycznych|journal=Slavia Antiqua|volume=23|pages=105–106}}</ref><ref name="Paszkiewicz1977">{{cite book|last=Paszkiewicz|first=Henryk|title=The Making of the Russian Nation|url=https://books.google.com/books?id=leTXAAAAMAAJ|year=1977|publisher=Greenwood Press|isbn=978-0837187570|page=359}}</ref><ref name="Braun1985">{{cite book|last=Braun|first=Jerzy|title=Poland in Christian Civilization|url=https://books.google.com/books?id=K7LZAAAAMAAJ|year=1985|publisher=Veritas Foundation Publication Centre|page=114|isbn=978-0901215796}}</ref><ref name="Kalhous2012">{{cite book|last=Kalhous|first=David|title=Anatomy of a Duchy: The Political and Ecclesiastical Structures of Early P?emyslid Bohemia|url=https://books.google.com/books?id=hY-JMg8Cd-0C|year=2012|publisher=Brill|isbn=978-9004229808|pages=94–96}}</ref>

Some historians suggest that the regions of Sandomierz, [[Lublin]] and Czerwień (western [[Red Ruthenia]]) were indeed annexed by Mieszko's state in the 970s, as lands valuable for trade reasons and as a starting point for a future attack against what was to become Lesser Poland, then in the hands of Bohemia. Sandomierz under this scenario was the central hub of the area, with Czerwień, Przemyśl and [[Chełm]] assuming the function of defensive borderland strongholds.<ref>A.
