Latium (/ˈleɪʃiəm/ LAY-shee-əm, US also /-ʃəm/ -shəm;[1][2][3][4] Latin: [ˈɫati.ũː]) is the historical region of central western Italy in which the city of Rome was founded and grew to be the capital city of the Roman Empire. The region existed in several historical forms: Latium vetus ('Old Latium') was the original homeland of the Latin tribes centered around the Alban Hills; Latium adiectum ('New Latium') encompassed the additional territories conquered by Rome to the south. The modern Italian administrative region of Lazio (also called Latium in Latin) covers roughly the same area with some additions.
