The old theory mainly represented by
Joachim Herrmann, who argued 7th century second wave immigration origin of later archaeological groups which replaced Sukow, is rejected by now. In that period only arrived first Slavic people of Sukow culture who didn't build yet strongholds. • Feldberg-type, also known as Feldberg-
Kędrzyny or Feldberger-
Gołańcz-Kędrzyny in Poland, appeared mainly in Pomerania and Mecklenburg, but also Little Poland and Southern Silesia, from mid-8th to late 9th century but in some parts was preserved until 9-10th century. Based on data collected, L. R. Lozny in 2013 considered that a minor percentage already appeared in the end of 7th and early 8th century. • Menkendorf-type, also known as Menkendorf-
Szczecin in Poland, followed Feldberg-type from late 8th or early 9th until the end of 10th century. == See also ==
