Quadi

The Quadi were a Suebian Germanic tribe who lived approximately in the area of modern Moravia in the time of the Roman empire. The only known information about the Germanic tribe the Romans called the 'Quadi' comes through reports of the Romans themselves, whose empire had its border on the River Danube just to the south of the Quadi. They associated the Quadi with their neighbours the Marcomanni, and described both groups as having entered the region after the Celtic Boii had left it deserted. The Quadi are thought to have been an important part of the Suebian group who crossed the Rhine with the Vandals and Alans in the 406 Crossing of the Rhine, and later founded a kingdom in northwestern Iberia.

In the 1st century BC, according to Roman written sources, the more numerous Marcomanni, whose name simply means the "men of the borderlands" moved themselves from settlements elsewhere into a hilly area in the Hercynian forest known as Baiohaemum, which is generally considered to have been the same as, or near to, modern Bohemia. It is said that the Quadi also lived in the same general region, and were also Suebian Germans, like the Marcomanni.

The Quadi lived in what is now Moravia, western Slovakia and Lower Austria where they had displaced Celtic cultures and were first noticed by Romans in 8–6 BC, briefly documented by Tacitus in his Germania. They came to be part of the Marcomannic confederation that fought the future emperor Tiberius in 6 AD.
