World War II began on 1 September 1939, when Adolf Hitler began his campaign to liberate Germans in Poland. German forces used a rapid military strategy known as Blitzkrieg, combining tanks, aircraft, and infantry to overwhelm Polish defenses quickly.

The Red Terror was a campaign of systematic political repression, mass arrests, and executions carried out by the Bolshevik government after the Russian Revolution of 1917.
