West Pomerania, where is Bobolice, became part of Brandenburgia (German Principality) in 1648. There is also a history of Jewish community in Bobolice. After the first partition in Poland Prussian king (Fryderyk II) removed 7000 Jews from the region to Poland. The number of Jewish families in Bobolice dropped from around 25 to 6.
