Mussolini at the March on Rome.The turbulence that followed the devastations of World War I, inspired by the Russian Revolution, led to turmoil and anarchy. The liberal establishment, fearing a socialist revolution, started to endorse the small National Fascist Party, led by Benito Mussolini. In October 1922 the fascists attempted a coup (the Marcia su Roma, "March on Rome"), but the king ordered the army not to intervene, instead forming an alliance with Mussolini. Over the next few years, Mussolini banned all political parties and curtailed personal liberties, thus forming a dictatorship. In 1935, Mussolini subjugated Ethiopia after a surprisingly lengthy campaign. This resulted in international alienation and the exodus of the country from the League of Nations. A first pact with Nazi Germany was concluded in 1936, and a second in 1938. Italy strongly supported Franco in the Spanish civil war. The country was opposed to Hitler's annexations of Austria, but did not interfere with it. Italy supported Germany's annexation of Sudetenland, however.

On 7 April 1939 Italy occupied Albania, a de facto protectorate for decades, and entered World War II in 1940, taking part in the late stages of the Battle of France. Mussolini, wanting a quick victory like Hitler's blitzkriegs in Poland and France, invaded Greece in October 1940 via Albania but was forced to accept a humiliating defeat after a few months. At the same time, Italy, after initially conquering British Somalia, saw an allied counter-attack lead to the loss of all possessions in the Horn of Africa. Italy was also defeated by British forces in North Africa and was only saved by the urgently dispatched German Africa Corps led by Erwin Rommel. Italy was invaded by the Allies in June 1943, leading to the collapse of the fascist regime and the arrest of Mussolini. In September 1943, Italy surrendered. The country remained a battlefield for the rest of the war, as the allies were moving up from the south and the north was the base for loyalist Italian fascist and German Nazi forces. The whole picture bacame more complex by the activity of the Italian partisans; see Italian resistance movement. The Nazis left the country on 25 April 1945. This led to the eventual disbanding of Italian fascist forces like the Black Brigades.

The Italian Republic (1946-)

Partisans parading in Milan after the liberation of the city.In 1946, Vittorio Emanuele III's son, Umberto II, was forced to abdicate. Italy became a republic after a referendum held on 2 June 1946, a day celebrated since as Republic Day. This was the first election in Italy allowing women to vote. The Republican Constitution was approved and came into force on 1 January 1948. Under the Paris Peace Treaties of 1947, the eastern border area was lost to Yugoslavia, and the free territory of Trieste was divided between the two states. Fears in the Italian electorate of a possible Communist takeover proved crucial for the first universal suffrage electoral outcome on the 18th of April 1948 when the Democrazia Cristiana, under the undisputed leadership of Alcide De Gasperi, won a resounding victory with 48 percent of the vote. In the 50s Italy became a member of the NATO alliance and an ally of the United States, which helped to revive the Italian economy through the Marshall Plan: until the 60s the country saw a period of prolonged economic growth termed the "Economic Miracle". In 1957, Italy was a signatory to the Treaties of Rome founding the European Economic Community (EEC), which became the European Union (EU) in 1993.

From the late 1960s till late 1980s the country experienced a hard economic crisis and the Years of Lead, a period characterised by widespread social conflicts and terrorist acts carried out by extra-parliamentary movements. The Years of Lead culminated in the assassination of the Christian Democracy (DC) leader Aldo Moro in 1978, bringing to an end the "Historic Compromise" between the DC and the Communist Party. In the 1980s, for the first time since 1945, two governments were led by non-Christian-Democrat premiers: a republican (Giovanni Spadolini) and a socialist (Bettino Craxi); the DC remained, however, the main force supporting the government. The Socialist Party (PSI), led by Bettino Craxi, became more and more critical of the Communists and of the Soviet Union; Craxi himself pushed in favour of US president Ronald Reagan's positioning of Pershing missiles in Italy, a move the Communists hotly contested.

The 1957 Treaties of Rome signing ceremony.From 1992 to 2009, Italy faced significant challenges, as voters, disenchanted with past political paralysis, massive government debt, extensive corruption, and organized crime's considerable influence (collectively called Tangentopoli after being uncovered by Mani pulite - "Clean hands") demanded political, economic, and ethical reforms. The scandals involved all major parties, but especially those in the government coalition: between 1992 and 1994 the DC underwent a severe crisis and was dissolved, splitting up into several pieces, while the PSI and the other governing minor parties completely dissolved. The 1994 elections put media magnate Silvio Berlusconi into the Prime Minister's seat. However, he was forced to step down in December when the Lega Nord Party withdrew its support. In April 1996, national elections led to the victory of a centre-left coalition under the leadership of Romano Prodi. Prodi's first government became the third-longest to stay in power before he narrowly lost a vote of confidence, by three votes, in October 1998. A new government was formed by Massimo D'Alema, but in April 2000 he resigned. In 2001, national elections led to the victory of a centre-right coalition under the leadership of Silvio Berlusconi, the centre-right formed a government, and Silvio Berlusconi was able to remain in power for a complete five-year mandate, but with two different governments. The first one (2001–2005) became the longest-lived government in post-war Italy. Italy participated in the US-led military coalition in Iraq. The elections in 2006 were won by the centre-left, allowing Prodi to form his second government, but in early 2008 he resigned because of the collapse of his coalition. In the ensuing new early elections in April 2008, Silvio Berlusconi convincingly won to form a government for a third time.
