Kiev offensive (1920)

Part of the Polish–Soviet War

The 1920 Kiev offensive (or Kiev expedition, Polish: wyprawa kijowska) was a major part of the Polish–Soviet War. It was an attempt by the armed forces of the recently established Second Polish Republic led by Józef Piłsudski, in alliance with the Ukrainian People's Republic led by Symon Petliura, to seize the territories of modern-day Ukraine which mostly fell under Soviet control after the October Revolution as the Russian Soviet Republic. Polish and Soviet forces fought in 1919 and the Poles advanced in the disputed borderlands.
