Origins & Early Life

The Treaty of Warsaw (also the Polish–Ukrainian or Petliura–Piłsudski Alliance or Agreement) of April 1920 was a military-economical alliance between the Second Polish Republic, represented by Józef Piłsudski, and the Ukrainian People's Republic, represented by Symon Petliura, against Bolshevik Russia. The treaty was signed on 21 April 1920, with a military addendum on 24 April. The alliance was signed during the Polish-Soviet War, just before the Polish Kiev offensive.

Career & Major Achievements

Piłsudski was looking for allies against the Bolsheviks and hoped to create a Międzymorze alliance; Petliura saw the alliance as the last chance to create an independent Ukraine. The treaty had no permanent impact.

Enduring Legacy & Impact

The Polish-Soviet War continued and the territories in question were distributed between Russia and Poland in accordance with the 1921 Peace of Riga. Territories claimed by the Ukrainian national movement were split between the Ukrainian SSR in the east and Poland in the west (Galicia and part of Volhynia).
