How did the Roman Province of Narbonensis become Provence?

The Roman province of Narbonensis became known as Provence because it was the first Roman provincia (province) established beyond the Alps in what is now southeastern France.12

Following the Roman conquest of the region in the late 2nd century BCE, the area was originally referred to simply as Provincia—the "Province"—due to its status as the first Roman territory in the region. While it was later formally renamed Gallia Narbonensis during the reign of Augustus to distinguish it from other regions of Gaul, the original designation persisted in the local vernacular. Over time, this name evolved into the modern Provence, which remains the name for this historical and cultural region today.12
