1922

From top to bottom, left to right: The Irish Civil War erupts between pro- and anti-Treaty forces after the creation of the Irish Free State, plunging Ireland into a brutal struggle; the March on Rome brings Benito Mussolini and the National Fascist Party to power in the Kingdom of Italy, launching fascist rule; the discovery of the tomb of Tutankhamun in the Valley of the Kings by Howard Carter sparks worldwide fascination with ancient Egypt; the Burning of Smyrna devastates the city in the final phase of the Greco-Turkish War, causing massive destruction and a humanitarian crisis; the Washington Naval Treaty limits naval arms among leading powers to prevent another costly race; and the Treaty on the Creation of the Union of Soviet Socialist Republics forms the Soviet Union, uniting multiple republics under one federal government.
