Major historical events of the Prussian Partition included the 1772 annexation of the formerly Polish Prussia by Frederick II who quickly implanted 57,475 German families there in order to solidify his new acquisitions.[3] The Polish language was marginalized.[4] In 1793, the Kingdom of Prussia annexed Gdańsk (Danzig) and Toruń (Thorn), part of the Crown of Poland since 1457.
