Kingdom of Italy
The Kingdom of Italy (Regno d'Italia) was a single Italian state that lasted from 1861 to 1946. It was formed through the long process of unification (the Risorgimento) and was ruled by the House of Savoy. Victor Emmanuel II became the first king, and the capital moved from Turin to Rome in 1871.
Government and society
Italy began as a constitutional monarchy. The king held executive power, but ministers and Parliament ran the government. The Statuto Albertino was the governing constitution. In 1925, Benito Mussolini’s Fascist Party seized control, transforming the state into a one-party dictatorship that lasted until 1943. The population was predominantly Italian-speaking and largely Catholic.
Territory and colonies
Italy expanded its borders through the late 19th and early 20th centuries. It gained Veneto in 1866 and captured Rome in 1870, making Rome the capital. It built a colonial empire, including Eritrea and Libya, and later Somalia and parts of Ethiopia. After World War I, Italy acquired some territories in the Adriatic and the Dalmatian coast, though not all promises from the war treaties were fulfilled. In the 1930s Mussolini’s regime pursued aggressive expansion in Africa and Europe.
Economy and people
After unification, Italy was mostly rural and agricultural, with industry growing slowly at first. The north industrialized earlier, while the south remained poorer. The country built a modern railway network and invested in schools, though regional disparities persisted. Large waves of Italians emigrated abroad, especially to the Americas, in search of work and a better life.
World War I
Italy joined the Allies in 1915. The war was costly and controversial at home. Italy gained a few territories but felt it had won less than hoped, a sentiment later used by fascists as propaganda.
Rise of fascism
Mussolini and the Fascists promised order and national revival. In 1922 they seized power after the March on Rome, and by 1925 they had dismantled democratic checks and balances. The Lateran Treaty of 1929 granted independence to Vatican City and established Catholicism as the state church.
World War II
Italy aligned with Nazi Germany and entered World War II in 1940. Military campaigns in France, Greece, North Africa, the Balkans, and elsewhere went poorly, and by 1943 the regime faced collapse. Mussolini was ousted, and the country soon surrendered to the Allies. The German-occupied north hosted a puppet regime, while the south fought alongside Allied forces and a strong resistance movement.
End of the monarchy and birth of the republic
After the war, Italy held a constitutional referendum in 1946 on whether to keep the monarchy. The republic won, and the monarchy was abolished. Umberto II fled into exile, and Alcide De Gasperi led the new government. Italy joined NATO in 1949 and began rebuilding with aid from the Marshall Plan. The country later helped found the European Communities, which became the European Union.
Legacy
The Kingdom of Italy left a divided memory of modernization and national pride, but also regional gaps between the industrial north and agricultural south. Its 20th-century history, especially under fascism and during World War II, reshaped Italian politics, culture, and its place in the world.
