Political map of Russia & the former Soviet Union 30 April 1919 (Revolution in Europe): The successes of Soviet Russia inspired dreams and fears of revolution in war-weary Europe (Revolutions of 1917–23). The most serious outbreaks were in Hungary and Germany. However, there were no long term successes. Bela Kun's Hungarian Soviet Republic (Hungarian Soviet Republic) lasted half a year before being crushed by Romania. None of the numerous revolutions across Germany (German Revolution of 1918–19) survived more than a month.
