Italy, a European country with a long Mediterranean coastline, has left a powerful mark on Western culture and cuisine. Its capital, Rome, is home to the Vatican as well as landmark art and ancient ruins. Other major cities include Florence, with Renaissance masterpieces such as Michelangelo’s "David" and Brunelleschi's Duomo; Venice, the city of canals; and Milan, Italy’s fashion capital. 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. After various unsuccessful attempts, the Italian Wars of Independence and the Expedition of the Thousand resulted in the eventual unification of the country in 1861, now a great power after centuries of foreign domination and political division. From the late 19th century to the early 20th century, the new Kingdom of Italy rapidly industrialised, although mainly in the north, and acquired a colonial empire, while the south remained largely impoverished and excluded from industrialisation, fuelling a large and influential diaspora. Today, Italy has the third largest economy in the Eurozone and the eighth largest in the world. With 50.7 million tourists a year (2015), Italy is the fifth most visited country in international tourism. People mainly visit Italy for its art, cuisine, history, fashion and culture, its coastline and beaches, its mountains, and ancient monuments. The Roman Empire, Middle Ages, and renaissance have left many cultural artifacts for the Italian tourist industry to use. Many northern cities are also able to use the Alps as an attraction for winter sports, while coastal southern cities have the Mediterranean Sea to draw tourists looking for sun. Italy is also home to fifty-one UNESCO World Heritage Sites, the most in the world. Rome is the third most visited city in Europe with an average of 7–10 million tourists a year.
