Beeskow-Starkow

Beeskow-Storkow was a twin lordship in Lower Lusatia, held in the 14th century by the Strele family from castles including Beeskow.

The Strele male line died out in 1384, and the lordship passed to the Biebersteins. In 1518 Ulrich von Bieberstein mortgaged it to the bishop of Lebus, who made Beeskow castle his residence. It passed to Brandenburg-Küstrin in 1556, to the electors of Brandenburg in 1575, and was annexed by Prussia in 1742.
