The Russian Partition (Polish: zabór rosyjski), sometimes called Russian Poland, constituted the former territories of the Polish–Lithuanian Commonwealth that were annexed by the Russian Empire in the course of late-18th-century Partitions of Poland. The Russian acquisition encompassed the largest share of Poland's population, living on 463,200 km2 (178,800 sq mi) of land constituting the eastern and central territory of the previous commonwealth. The first partitioning led by imperial Russia took place in 1772; the next one in 1793, and the final one in 1795, resulting in Poland's loss of sovereignty and the reconstitution of the Kingdom of Poland within the Russian Empire in 1815.
