Final answer:
The Germanic peoples and the Roman state had a multifaceted relationship involving military alliances, conflicts, peaceful coexistence, and cultural assimilation. Germanic mercenaries served in the Roman military and later integrated into Roman society, contributing to a process of acculturation in the successor kingdoms of the Roman Empire.
Step-by-step explanation:
The relationship between Germanic peoples and the Roman state was complex, involving economic alliances, military conflicts, periods of peaceful coexistence, and cultural assimilation. The Romans deemed many Germanic groups as foederati, bound by treaties that granted them a semi-autonomous status in return for military service to the Empire. As a consequence, Germans served as mercenaries within the diverse Roman military and after their service, integrated into Roman society through various means, including settlement and acculturation.
Notably, the late Roman military often comprised barbarian troops, and the Romans had to constantly negotiate new treaties due to Germanic perceptions that treaties lasted only as long as the ruling emperor. This often led to incursions upon an emperor's death. The eventual blending of Germanic and Roman traditions resulted in acculturation, notably seen in the successor kingdoms of the Franks, Ostrogoths, and Visigoths.
