The later Silesian Province of Prussia further comprised the adjacent lands of historic Upper Lusatia ceded by the Kingdom of Saxony after the Napoleonic Wars in 1815, its westernmost point could be found as far west as the small village of Lindenau (now belonging to the German state of Brandenburg). To the north, Lower Silesia originally stretched up to Świebodzin and Krosno Odrzańskie, which was acquired by the Margraves of Brandenburg in 1482. The Barycz river forms the border with historic Greater Poland in the northeast, the Upper Silesian lands lie to the southeast.
