The Russian Partition (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 former commonwealth. The three partitions, which took place in 1772, 1793 and 1795, resulted in the complete loss of Poland's sovereignty, with its territory split between Russia, Prussia and Austria. The Napoleonic Wars saw significant parts of Prussia's and Austria's partitions reconstituted as the Duchy of Warsaw (a French client state in a personal union under Saxony), most of which was then reconstituted as the Kingdom of Poland within the Russian Empire in 1815.
To both Russians and Poles, the term Russian Poland was not acceptable. To the Russians after partition, Poland ceased to exist, and their newly acquired territories were considered the long lost parts of Mother Russia. To Poles, Poland was simply Polish, never Russian. While the Russians used varying administrative names for their new territories (see below), another popular term, used in Poland and adopted by most other historiographies, was the Russian Partition.
Even before the partitions from the late 18th century, the Russian Empire had already acquired some territories of the Polish–Lithuanian Commonwealth (a real union of Kingdom of Poland with the Grand Duchy of Lithuania). The first Russian partition took place in the late 17th century when the forced Treaty of Andrusovo signed in 1667 granted Russia the Commonwealth's territory in the Eastern Ukraine. Under the Third Partition of Poland Russia acquired Courland, all Lithuanian territory east of the Nieman River, and the remaining parts of Volhynian Ukraine.
Major historical events of the Russian Partition included the Warsaw Uprising (1794) soon after Kościuszko's victory at Racławice.
