Alemanni
a Germanic people first mentioned in connection with the Roman attack on them in AD 213. In the following decades, their pressure on the Roman provinces became severe; they occupied the Agri Decumates c. 260, and late in the 5th century they expanded into Alsace and northern Switzerland, establishing the German language in those regions. In 496 they were conquered by Clovis and incorporated into his Frankish dominions.
