Italy is largely homogeneous linguistically and religiously but is diverse culturally, economically, and politically. Italy has the fifth-highest population density in Europe — about 196 persons per square kilometer (490 per square mile).
The birth of the Italian republic (officially on June 2, 1946) is a key event of Italian contemporary history. It is controversial because of suspicions of fraud that were advanced by monarchists). Until 1946, Italy was a monarchy ruled by the House of Savoy (kings of Italy and, previously, of Sardinia). In 1946, after the results of a popular referendum, it became a republic. A Constituent assembly was elected at the same time to prepare a new constitution for the Republic. This article is about the Referendum on the form of State.
Italy has a diversified industrial economy with roughly the same total and per capita output as France and the United Kingdom. This capitalistic economy remains divided into a developed industrial north, dominated by private companies, and a less developed agricultural south, with 20% unemployment. In comparison to its western European neighbours, it has a high number of small to medium sized enterprises (SMEes).
Italy was invaded by the Visigoths in the 5th century, and Rome was sacked by Alaric in 410. By the end of the century the peninsula was mostly under Ostrogothic control, and the last Roman emperor, Romulus Augustus, was deposed in 476 by Theodoric the Great. The eastern half of the Empire, now centred on Constantinople, invaded Italy in the early 6th century, and the generals of emperor Justinian, Belisarius and Narses, conquered the Ostrogothic kingdom after years of warfare. The collapse of the Ostrogoths allowed the Lombards to fill the gap, and the Eastern Empire could not hold on to its reconquered territory against the Lombard invasion. The Lombards ruled Italy until the late 8th century when their kingdom was conquered by Charlemagne.
After the invasion of Soviet Union failed (1941-42), and the United States entered the war (December 1941), the situation for the Axis started to deteriorate. In May 1943 the Anglo-Americans completely defeated the Italians and the Germans in North Africa, and in July they landed in Sicily. King Victor Emmanuel III reacted by arresting Mussolini and appointing the army chief of staff, Marshal Badoglio, as Prime Minister.
Italy's dramatic self-renewal transformed the political landscape between 1992 and 1997. Scandal investigations touched thousands of politicians, administrators, and businessmen; the shift from a proportional to an Additional Member System (with the requirement to obtain a minimum of 4% of the national vote to obtain representation) also altered the political landscape.
The Church (and especially the bishop of Rome, the pope) had played an important political role since the times of Constantine, who tried to include it in the imperial administration.
Italy consists predominantly of a large peninsula with a distinctive boot shape that extends into the Mediterranean Sea, where together with its two main islands Sicily and Sardinia it creates distinct bodies of water, such as the Adriatic Sea to the north-east, the Ionian Sea to the south-east, the Tyrrhenian Sea to the south-west and finally the Ligurian Sea to the north-west.
The U.S.-Italian bilateral relationship is strong and growing. The U.S. and Italy cooperate closely on major economic issues, including within the G-8, which met in Genoa in July 2001. With a large population and a high per capita income, Italy is one of the United States' most important trade partners. In 2000 the United States was the fifth-largest foreign supplier of the Italian market and the largest supplier outside the EU. Total trade between the United States and Italy exceeded $33 billion in 1999. The U.S. ran a $12.1 billion deficit with Italy in 2000.
