From Wikipedia, the free encyclopedia: Italy, officially the Italian Republic (Italian: Repubblica italiana), is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of 301,338 km2 (116,347 sq mi) and has a largely temperate seasonal climate; due to its shape, it is often referred to in Italy as lo Stivale (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state. Since classical times, ancient Carthaginians, Phoenicians, and Greeks established settlements in the south of Italy, with Etruscans and Celts inhabiting the centre and north of Italy respectively and various different Italic tribes and peoples dispersed throughout the country. The Italic tribe known as the Latins formed the Roman Kingdom, which eventually became a republic that conquered and assimilated other nearby civilisations. Rome ultimately emerged as the dominant power in the Mediterranean basin, conquering much of the ancient world and becoming the leading cultural, political, and religious centre of Western civilisation. The legacy of the Roman Empire is widespread and can be observed in the global distribution of civilian law, republican governments, Christianity and the Latin script. At the Lucca Conference, in 56 BC, Julius Caesar, Pompey, and Crassus reaffirmed their political alliance known as the First Triumvirate. Piazza dell'Anfiteatro and the Basilica of San Frediano Frediano, an Irish monk, was bishop of Lucca in the early sixth century. At one point, Lucca was plundered by Odoacer, the first Germanic King of Italy. Lucca was an important city and fortress even in the sixth century, when Narses besieged it for several months in 553. Under the Lombards, it was the seat of a duke who minted his own coins. The Holy Face of Lucca (or Volto Santo), a major relic supposedly carved by Nicodemus, arrived in 742. During the eighth-tenth centuries Lucca was a center of Jewish life, the community being led by the Kalonymos family (which at some point during this time migrated to Germany to become a major component of proto-Ashkenazic Jewry). Lucca became prosperous through the silk trade that began in the eleventh century, and came to rival the silks of Byzantium. During the tenth–eleventh centuries Lucca was the capital of the feudal margraviate of Tuscany, more or less independent but owing nominal allegiance to the Holy Roman Emperor.
