Italy 2021 2€ Rome

Rome has been a major human settlement for almost three millennia.
The city successively became the capital of the Roman Kingdom, the Roman Republic and the Roman Empire, and is regarded by many as the first ever Imperial city and metropolis.It was first called The Eternal City by the Roman poet Tibullus. Rome is also called "Caput Mundi" (Capital of the World). After the fall of the Empire in the west, which marked the beginning of the Middle Ages, Rome slowly fell under the political control of the Papacy, and in the 8th century it became the capital of the Papal States, which lasted until 1870. Beginning with the Renaissance, almost all popes since Nicholas V (1447–1455) pursued a coherent architectural and urban programme over four hundred years, aimed at making the city the artistic and cultural centre of the world.
In 1871, Rome became the capital of the Kingdom of Italy, which, in 1946, became the Italian Republic.
