The Polish–Soviet War followed the First World War, when the newly independent Poland under Józef Piłsudski sought to secure its eastern borders while Soviet Russia hoped to spread revolution westward. Polish forces advanced into Ukraine and took Kyiv in 1920, but the Red Army counterattacked and reached the outskirts of Warsaw in August. In the Battle of Warsaw the Poles won a decisive victory, often called the Miracle on the Vistula, and drove the Soviet forces back. The war ended with the Treaty of Riga in March 1921, which placed the border well east of the Curzon Line and left large Ukrainian and Belarusian populations inside Poland. The outcome halted the westward advance of Bolshevism for the time being.
