Naples is the capital of the Italian region Campania and the third-largest municipality in Italy, after Rome and Milan. In 2015, around 975,260 people lived within the city's administrative limits. The Metropolitan City of Naples had a population of 3,115,320. Naples is the 9th-most populous urban area in the European Union with a population of between 3 million and 3.7 million. About 4.4 million people live in the Naples metropolitan area, one of the largest metropolises on the Mediterranean Sea.
Naples is one of the oldest continuously inhabited cities in the world. Bronze Age Greek settlements were established in the Naples area in the second millennium BC. A larger colony developed on the Island of Megaride around the ninth century BC, at the end of the Greek Dark Ages. Naples remained influential after the fall of the Western Roman Empire, serving as the capital city of the Kingdom of Naples between 1282 and 1816. Thereafter, in union with Sicily, it became the capital of the Two Sicilies until the unification of Italy in 1861.
Naples was the most-bombed Italian city during World War II. Much of the city's 20th-century periphery was constructed under Benito Mussolini's fascist government, and during reconstruction efforts after World War II. In recent decades, Naples has constructed a large business district, the Centro Direzionale, and has developed an advanced transport infrastructure, including an Alta Velocità high-speed rail link to Rome and Salerno, and an expanded subway network, which is planned to eventually cover half of the region. The city has experienced significant economic growth in recent decades, and unemployment levels in the city and surrounding Campania have decreased since 1999. However, Naples still suffers from political and economic corruption, and unemployment levels remain high.
