Rome's history spans more than two and a half thousand years, since its founding in 753 BC, with the union of rural villages. It was the capital city of the Roman Kingdom, the Roman Republic and the Roman Empire, which was the dominant power in Western Europe and the lands bordering the Mediterranean for over seven hundred years from the 1st century BC until the 7th century AD and the city is regarded as one of the birthplaces of western civilization.
Since the 1st century AD Rome has been the seat of the Papacy and, after the end of Byzantine domination, in the 8th century it became the capital of the Papal States, which lasted until 1870. In 1871 Rome became the capital of the Kingdom of Italy, and in 1946 that of the Italian Republic. After the Middle Ages, Rome was ruled by popes such as Alexander VI and Leo X, who transformed the city into one of the major centers of the Italian Renaissance, along with Florence. The current version of St Peter's Basilica was built and the Sistine Chapel was painted by Michelangelo. Famous artists and architects, such as Bramante, Bernini and Raphael resided for some time in Rome, contributing to its Renaissance and Baroque architecture. Rome has been ranked by GaWC in 2010 as a beta+ world city, as well as the 28th most important global city. In 2007, Rome was the 11th-most-visited city in the world, 3rd most visited in the European Union, and the most popular tourist attraction in Italy. The city is one of Europe's and the world's most successful city "brands", both in terms of reputation and assets. Its historic centre is listed by UNESCO as a World Heritage Site. Monuments and museums such as the Vatican Museums and the Colosseum are amongst the world's 50 most visited tourist destinations (the Vatican Museums receiving 4.2 million tourists and the Colosseum receiving 4 million tourists every
ear).Rome hosted the 1960 Summer Olympics. There is archaeological evidence of human occupation of the Rome area from at least 14,000 years ago, but the dense layer of much younger debris obscures Palaeolithic and Neolithic sites. Evidence of stone tools, pottery and stone weapons attest to at least 10,000 years of human presence. Several excavations supports the view that Rome grew from pastoral settlements on the Palatine Hill built above the area of the future Roman Forum. While some archaeologists argue that Rome was indeed founded in the middle of the 8th century BC (the date of the tradition), the date is subject to controversy. However, the power of the well known tale of Rome's legendary foundation tends to deflect attention from its actual, and much more ancient, origins. Sabines, the Etruscans, the Samnites and most of the Greek colonies in Sicily, Campania and Southern Italy in general.
During the Punic Wars between Rome and the great Mediterranean empire of Carthage, Rome's stature increased further as it became the capital of an overseas empire for the first time. Beginning in the 2nd century BC, Rome went through a significant population expansion as Italian farmers, driven from their ancestral farmlands by the advent of massive, slave-operated farms called latifundia, flocked to the city in great numbers. The victory over Carthage in the First Punic War brought the first two provinces outside the Italian peninsula, Sicily and Corsica et Sardinia. Parts of Spain (Hispania) followed, and in the beginning of the 2nd century the Romans got involved in the affairs of the Greek world. By then all Hellenistic kingdoms and the Greek city-states were in decline, exhausted from endless civil wars and relying on mercenary troops. This saw the fall of Greece after the Battle of Corinth (146 BC) and the establishment of Roman control over Greece
