Rome's history spans more than two and a half thousand years, since its legendary founding in 753 BC. Rome is one of the oldest continuously occupied cities in Europe. It is referred to as "The Eternal City", a notion expressed by ancient Roman poets and writers. In the ancient world it was successively the capital city of the Roman Kingdom, the Roman Republic and the Roman Empire, and is regarded as one of the birthplaces of Western civilization. Since the 1st century AD, Rome has been considered the seat of the Papacy and 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 among the world's most visited tourist destinations with both locations receiving millions of tourists a year.
