Revolutions

The Revolutions of 1917–1923 were a wave of political instability and revolts that swept the globe, spurred on by the victory of the Russian Revolution and the chaos generated by World War I's aftermath. The majority of the revolutions were socialist or anti-colonial. Some socialist uprisings did not result in the establishment of long-term socialist nations. The revolutions had a long-term impact on the political landscape of Europe, as seen by the collapse of the German Empire and the abdication of the German Kaiser.

World War I resulted in the mobilization of a million troops, social upheaval, and reconfiguration of governmental forces, resulting in the outbreak of the revolution, widespread strikes, and army mutiny. It also resulted in the Tsar's fall, the monarchy's overthrow, and the Russian Civil War during the 1917 Russian Revolution. A socialist revolution erupted in Germany in 1918, resulting in the establishment of the Weimar Republic, which lasted until 1930.

During this time, the Irish War of Independence (1919-20), the Hungarian Revolution (1918-20), the Egyptian Revolution (1919), and several other revolutionary events took place. The majority of these revolutions were short-lived and anti-colonial or socialist.
