Chatti

The Chatti were a Roman era Germanic people that lived in a region approximately corresponding to the modern German federal state of Hesse. The Chatti were among the most important opponents of the Roman Empire during the Roman campaigns in Germania which were pursued under the emperor Augustus and his heirs. In this context they were among the defeated opponents of Drusus the Elder, during his Germanic campaigns from 12 BC until his death in 9 BC. Subsequently, they also appear to have been involved in the revolt against Rome which was led by Arminius of the Cherusci, although there is no record of them being present at the Battle of the Teutoburg Forest in 9 AD which initiated these wars. The Chatti and Cherusci nobility were connected by marriage during this period.
