Polish-Soviet War

For other Russo-Polish conflicts see Russo-Polish War The Polish-Soviet War (February 1919 – March 1921) was an armed conflict of Soviet Russia and Soviet Ukraine against the Second Polish Republic and the Ukrainian People's Republic, four nascent states in post-World War I Europe. The war was the result of conflicting expansionist attempts. Poland, whose statehood had just been re-established by the Treaty of Versailles following the Partitions of Poland in the late 18th century, sought to secure territories which she had lost at the time of partitions; the Soviets' aim was to control those same territories, which had been part of Imperial Russia until the turbulent events of the Great War. Both States claimed victory in the war: the Poles claimed a successful defense of their state, while the Soviets claimed a repulse of the Polish eastward invasion of Ukraine and Belarus, which they viewed as a part of foreign intervention in the Russian Civil War.
