The Polish–Soviet War was fought primarily between the Second Polish Republic and the Russian Soviet Federative Socialist Republic before it became a union republic in the aftermath of World War I and the Russian Revolution, on territories which were previously held by the Russian Empire and the Habsburg Monarchy following the Partitions of Poland.

The Second Polish Republic, at the time officially known as the Republic of Poland, was a country in Central and Eastern Europe that existed between 7 October 1918 and 6 October 1939. The state was established in the final stage of World War I. The Second Republic ceased to exist in 1939, after Poland was invaded by Nazi Germany, the Soviet Union, and the Slovak Republic, marking the beginning of the European theatre of the Second World War. The Polish government-in-exile was established in Paris and later London after the fall of France in 1940.
