out lucrative trade with Magna Germania, which greatly contributed to the wealth of Roman Gaul. Germania (98 AD) by Tacitus provided vivid descriptions of the peoples of Magna Germania. In the late 1st and early 2nd century AD, the Romans reoccupied areas lying between the Rhine, Main, and Danube rivers. This area became known as the Agri Decumates. Additional numbers of Germani were settled by the Romans within this area. The Roman fortifications on the border with Magna Germania were known as the Limes Germanicus. The 3rd century AD saw the emergence of several powerful Germanic confederations in Magna Germania, such as the Alemanni and Franks. The Crisis of the Third Century included raids on Roman Germania by Alemanni and Franks, and the area briefly became part of the Gallic Empire established by the usurper Postumus. Around 280 AD, the Agri Decumates were evacuated by the Romans and occupied by Alemanni. Under Diocletian (3rd century AD), Germania Superior was renamed Germania Secunda, while Germania Inferior was renamed Maxima Sequanorum. Both provinces were under the Diocese of Gaul. The provinces of Roman Germania continued to be subjected to repeated Alemannic and Frankish attacks. In the late 4th century AD and early 5th century AD, Gothic Wars in the Balkans forced the Romans to withdraw troops from Roman Germania. In 406, a large number of people fleeing the Huns crossed the Rhine from Magna Germania into Roman Germania and Gaul, leading to the eventually collapse of Roman rule there, and the emigration of large numbers of Romans, particularly Roman elites. Roman Germania was subsequently occupied by Alemanni and Franks. During subsequent centuries, peoples of Germania played a major role in dismembering what was left of the Western Roman Empire. Large parts of Germania, including all of Roman Germania, were eventually incorporated into the Frankish Empire. Archaeology From the 1st to the 4th century AD, Magna Germania corresponds archaeologically to the Roman Iron Age. In recent years, progress in archaeology has contributed greatly to the understanding of Germania. Areas of Magna Germania were largely agrarian, and display archaeological commonalities with each other, while being strongly differentiated from that of Roman Germania, largely due to the absence of cities and independent coinage. Archaeological discoveries testify to flourishing trade between Magna Germania and the Roman Empire. Amber was a primary export out of Magna Germania, while Roman luxury goods were imported on a large scale.
