Sukow-Dziedzice group

Areal of sites lays between Elbe and Vistula rivers in Northeast Germany and North West Poland.

[4][5] Most recent studies, based on dendrochronological evidence, conclude there is little evidence of a Slavic presence in Eastern Germany and Northwestern Poland before the end of the 7th or the early 8th century, and there was only sparse settlement till the 9th century.

[6] Also, "palynological observations indicate a fast and drastic reduction in settlement during the sixth and seventh centuries, as it is shown by a minimum of cerealia and an increasing proportion of trees; nevertheless a total lack of settlement can not be deduced".

[9] 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.
