In the aftermath of the battle, Arminius fought retaliatory invasions by the Roman general Germanicus in the battles of Pontes Longi, Idistaviso, and the Angrivarian Wall, and deposed a rival, the Marcomanni king Maroboduus. Germanic nobles, afraid of Arminius' growing power, assassinated him in 21 AD. He was remembered in Germanic legends for generations afterwards. The Roman historian Tacitus designated Arminius as the liberator of the Germanic tribes and commended him for having fought the Roman Empire to a standstill at the peak of its power.
