Wielki dzień Skalina (7 IV 1269), początki Choszczna i pomorskich von Kleistów. W tle konflikt księcia Barnima I, jego rycerstwa z ziemi stargardzkiej i cystersów kołbackich z joannitami oraz interwencja margrabiów brandenburskich w zlewni lewobrzeżn

Much was going on in 1269, particularly in its first half, in the duchies in Pomerania, both that called today “West”, and its surroundings (in Vistula Pomerania, Brandenburg, Mecklenburg, and the remaining political entities of Northern Germany), not without significance for this part of Pomerania where Skalin, a village south-east from Stargard on Ina, is located. We still encounter difficulties to interpret those numerous events. In order to remind and explain the subject and reasons of knight Konrad “Clest’s” activities in Skalin on 7 April 1269 and the circumstances that preceded them, the author reminded and interpreted among others: relationships of Duke Barnim I with the Brandenburg margraves in January that year, conflict of Barnim I, his knights from the Stargard Land, and the Cistercians from Kołbacz with the Joannites from the Stargard Land and the Choszczno Land (village Korytowo), intervention of the margraves expelling those Cistercians in 1269 from their manor “in Sowno”, i.e. located by the lake “Sowno” (Zouina, Sovin), meeting of the Brandenburg margraves on 1st April 1269 in Arbswalde/Choszczno with Mestwin II, Duke of Świecie (with the centre in Świecie on Vistula in Vistula Pomerania), who paid homage to them. Discussed were also the origins of Choszczno (after identifying it with the above mentioned “manor in Sowno”), and the origins of the knightly families von Kleist and von Blankenburg.
