The
Prussian deportations (or
Prussian expulsions, ) were mass expulsions of ethnic
Poles (and, to a lesser extent,
Jews) from
Prussia in between 1885–1890. More than 30,000 Poles with Austrian or Russian citizenship were deported from the
Prussian part of divided Poland to the respective
Austrian and
Russian parts. The deportations were carried out in an inhumane way, and were based on ethnic discrimination principles. The county-wide expulsion was condemned by the Polish public as well as the federal German parliament. The expulsion also contributed to the worsening of the German-Russian relations. In the aftermath, Poles without German citizenship were again allowed to work and reside in the German Empire in all seasons but the winter. It is regarded as an early example of ethnic cleansing.
