[3][4][5] It is generally named after Lower Lusatian village Tornow (district of Oberspreewald-Lausitz, Brandenburg),[6] which doesn't exist anymore since mid-20th century and where were held extensive archaeological excavations in the 1960s.
[7][8] Since 1980s the data was critically evaluated and old model rejected - they are not from 7th century early-Slavic but later middle-Slavic period with Carolingian influence.
[22][23] Tornow pottery was technologically more advanced from both Feldberg and Menkendorf group,[24] almost resembling Late Slavic tradition.
[30] It is argued to have been seats of local tribal chiefs,[6] and possibly indicate a turbulent period of events when on the territory of Lusatian lands clashed German, Moravian-Bohemian, and Polish military forces in the 10th century.
[31] According to Ludomir R. Lozny, the dynamic Slavic social and political events and the Carolingian Empire expansion in North Central European Plains (NCEP) possibly resulted with the wide "Tornow Interaction Sphere" (TIS) of specific forts, villages and mixture of pottery types, but not a "state-level polity".
