One of the most decisive battles of world history occurred outside of Warsaw  in  August 1920. The Soviet Army invaded Poland to link up with Communist revolutionaries in Germany. Their goal was to install Communist regimes all over Europe and spread the Bolshevik revolution. After  series of defeats the Polish Army was pushed back to Warsaw, but ended up defeating the Soviet invasion force.

The 2011 Polish movie Battle of Warsaw 1920 celebrated the miraculous Polish victory over the Red Army.
