Durocortorum was the name of the city Reims during the Roman era. It was the capital of the Remi tribe and the second largest city in Roman Gaul. Before the Roman conquest of northern Gaul, the city was founded circa 80 BC, served as the capital of the tribe of the Remi. In the course of Julius Caesar's conquest of Gaul (58–51 BC), the Remi allied themselves with the Romans, and, by their fidelity throughout the various Gallic insurrections, secured the special favour of imperial power. At its height in Roman times the city had a population in the range of 30,000 – 50,000 or perhaps up to 100,000, and was an important node in the road system of Gallia Belgica. After the installation of Magnus Maximus in Augusta Treverorum, Durocortorum was renamed Metropolis Civitas Remorum, and no longer served as the capital of Gallia Belgica although it remained the capital of Belgica Secunda. Etymology and historical mentions The Latin Durocortōrum comes from the Celtic "Durocorteron" ("round fortress"). It was an oppidum of the tribe of the Remi founded circa 80 BC, and served as its capital.
