The Russian Empire and the Kingdom of Prussia partitioned the Polish–Lithuanian Commonwealth for the second time.

The Russian Empire was an empire that spanned most of northern Eurasia from its establishment in November 1721 until the proclamation of the Russian Republic in September 1917. At its height in the late 19th century, it covered about 22,800,000 km² (8,800,000 sq mi), roughly one-sixth of the world's landmass, making it the third-largest empire in history, behind only the British and Mongol empires. It also colonized Alaska between 1799 and 1867. The empire's 1897 census, the only one it conducted, found a population of 125.6 million with considerable ethnic, linguistic, religious, and socioeconomic diversity.

The Kingdom of Prussia was a German state that existed from 1701 to 1918. It played a significant role in the unification of Germany in 1871 and was a major constituent of the German Empire until its dissolution in 1918. Although it took its name from the region called Prussia, it was based in the Margraviate of Brandenburg. Its capital was Berlin.

The Polish–Lithuanian Commonwealth, also referred to as Poland–Lithuania or the First Polish Republic, was a federative real union between the Kingdom of Poland and the Grand Duchy of Lithuania, existing from 1569 to 1795. This state was among the largest, most populated countries of 16th- to 18th-century Europe. At its peak in the early 17th century, the Commonwealth spanned approximately 1,000,000 km² (390,000 sq mi) and supported a multi-ethnic population of around 12 million as of 1618. The official languages of the Commonwealth were Polish and Latin, with Catholicism as the state religion.

The 1793 Second Partition of Poland was the second of three partitions that ended the existence of the Polish–Lithuanian Commonwealth by 1795. The second partition occurred in the aftermath of the Polish–Russian War of 1792 and the Targowica Confederation of 1792, and was approved by its territorial beneficiaries, the Russian Empire and the Kingdom of Prussia. The division was ratified by the coerced Polish parliament (Sejm) in 1793 in a short-lived attempt to prevent the inevitable complete annexation of Poland, the Third Partition.
