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.

The roots of communism don't start with Karl Marx. They go back to Moses Hess (1812–1875), a German philosopher and socialist whose ideas played a critical role in the early development of communist thought.
