The Apennine mountains form the backbone of this peninsula, leading north-west to where they join the Alps, the mountain range that then forms an arc enclosing Italy from the north. Here is also found a large alluvial plain, the Po-Venetian plain, drained by the Po River and its many tributaries flowing down from the Alps, Apennines and Dolomites. Other well-known rivers include the Tiber, Adige and Arno.
At the end of the 8th century the popes definitely aspired to independence, and found a way to achieve it by allying with the Carolingian dynasty of the Franks: the Carolingians needed someone who could give legitimacy to a coup against the powerless Merovingian kings, while the popes needed military protection against the Lombards. As a result, in 774 the Franks invaded and defeated the Lombards, and their leader Charlemagne was proclaimed legitimate king of the Franks by the pope. Later, in 800, Charlemagne was also crowned emperor of the Holy Roman empire by the pope; the new emperor (who was never recognized as such by the Byzantines) immediately conceded direct rule over central Italy to the pope, creating the Papal States.
Major political parties, beset by scandal and loss of voter confidence, underwent far-reaching changes. New political forces and new alignments of power emerged in March 1994 national elections. The election saw a major turnover in the new parliament, with 452 out of 630 deputies and 213 out of 315 senators elected for the first time. The 1994 elections also swept media magnate Silvio Berlusconi (leader of "House of Freedoms" (Casa delle Libertà) coalition) into office as Prime Minister. Berlusconi, however, was forced to step down in January 1995 when one member of his coalition withdrew support. The Berlusconi government was succeeded by a technical government headed by Prime Minister Lamberto Dini, which left office in early 1996.
Unions claim to represent 40% of the work force. Most Italian unions are grouped in three major confederations--the Italian General Confederation of Labor (CGIL), the Italian Confederation of Labor Unions (CISL), and the Union of Italian Labor (UIL), which together claim 35% of the work force. These confederations formerly were associated with important political parties or currents, but they have formally terminated such ties. Nowadays, the three often coordinate their positions before confronting management or lobbying the government. The three major confederations have an important consultative role on national social and economic issues.
From 1861 until 1922, Italy was a constitutional monarchy with a parliament, mostly elected with restricted suffrage (in 1913, the first universal male suffrage election was held). The so called Statuto Albertino, which Carlo Alberto conceded in 1848 remained unchanged, even if the kings usually abstained from abusing their extremely large powers (for example, senators were not elected but chosen by the king). The new state faced immense problems, both because of the widespread poverty and illiteracy (especially in the south), and the deep cultural differences (for example, there existed no common language) between the various parts of Italy: there were even peasant insurrections asking for the return of former rulers.
Italy's economic performance has at times lagged behind that of its EU partners, and the current government has enacted numerous short-term reforms aimed at improving competitiveness and long-term growth. It has moved slowly, however, on implementing certain structural reforms favored by economists, such as lightening the high tax burden and overhauling Italy's rigid labour market and expensive pension system, because of the current economic slowdown and opposition from labour unions.
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.
After the Lombard invasion, the popes (i.e. St. Gregory) were nominally subject to the eastern emperor, but often received little help from Constantinople, and had to fill the lack of stately power, protecting Rome from Lombard incursions; in this way, the popes started building an independent state.
Under longstanding bilateral agreements flowing from NATO membership, Italy hosts important U.S. military forces at Vicenza and Livorno (army); Aviano (air force); and Sigonella, Naples, and Gaeta – home port for the U.S. Navy Sixth Fleet. The United States has about 16,000 military personnel stationed in Italy. Italy hosts the NATO War College in Rome.
Italy has been a democratic republic since June 2, 1946, when the monarchy was abolished by popular referendum. The constitution was romulgated on January 1, 1948. The Italian State has a central state authority (the Government), 20 regions and about a hundred provinces. The prefect of each of the provinces is appointed by and responding to the central government, which he locally represents.
Even though much of its mountainous and nootinous terrain is unsuitable for farming, Italy has a large work force (1.4 million) employed in farming. Most farms are small, with the average farm only 7 hectares.
The 11th century signed the end of the darkest period in the middle ages. Trade slowly picked up, especially on the seas, where the four Italian cities of Amalfi, Pisa, Genoa and Venice became major powers. The papacy regained its authority, and started a long struggle with the empire, about both ecclesiastical and secular matter. The first episode was the Investiture controversy.
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).
Islam was almost entirely absent in Italy from the time of that country's unification in 1861 until the 1970s, when the first trickle of North African immigrants began arriving. These North Africans, mostly of Berber or Arab origin, came mainly from heavily Islamic Morocco, though they have been followed in more recent years by Tunisians, Albanians and to a lesser extent, Libyans, Egyptians, Pakistanis, Middle Eastern Arabs and Kurds. Some estimate the number of Italian converts to be around 10,000.
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.
