What is rhaetia?

Rhaetia, also known as Raetia, was an ancient region located in the eastern Alps, primarily encompassing parts of modern-day Switzerland, Italy, and Austria. It was inhabited by the Raeti, a group of Celtic tribes, and later became a Roman province in the 1st century BCE. The region was significant for its strategic location along trade routes and its rich mineral resources, particularly in mining. Rhaetia played an important role in the cultural and economic exchanges between the Romans and the local tribes.
