Arminius

Arminius (; 18/17 BC–AD 21; Hermann in German) was a chieftain of the Germanic Cherusci tribe who is best known for commanding an alliance of Germanic tribes at the Battle of the Teutoburg Forest in AD 9, in which three Roman legions under the command of general and governor Publius Quinctilius Varus were destroyed. His victory at Teutoburg Forest precipitated the Roman Empire's permanent strategic withdrawal and the deprovincialization of Germania Magna, and modern historians regard it as one of Imperial Rome's greatest defeats. As it prevented the Romanization of Germanic peoples east of the Rhine, it has also been considered one of the most decisive battles in history and a turning point in human history.

Born a prince of the Cherusci tribe, Arminius was part of the Roman-friendly faction of the tribe. He learned Latin and served in the Roman military, which gained him Roman citizenship, and the rank of eques. After serving with distinction in the Great Illyrian Revolt, he was sent to Germania to aid the local governor Publius Quinctilius Varus in completing the Roman conquest of the Germanic tribes. While in this capacity, Arminius secretly plotted a Germanic revolt against Roman rule, which culminated in the ambush and destruction of three Roman legions in the Teutoburg Forest.
