Germanic peoples occupied much of the present-day territory of Germany in ancient times. The Germanic peoples are those who spoke one of the Germanic languages, and they thus originated as a group with the so-called first sound shift (Grimm’s law), which turned a Proto-Indo-European dialect into a new Proto-Germanic language within the Indo-European language family. The Proto-Indo-European consonants p, t, and k became the Proto-Germanic f, [thorn] (th), and x (h), and the Proto-Indo-European b, d, and g became Proto-Germanic p, t, and k. The historical context of the shift is difficult to identify because it is impossible to date it conclusively. Clearly the people who came to speak Proto-Germanic must have been isolated from other Indo-Europeans for some time, but it is not obvious which archaeological culture might represent the period of the shift. One possibility is the so-called Northern European Bronze Age, which flourished in northern Germany and Scandinavia between about 1700 and 450 bc. Alternatives would be one of the early Iron Age cultures of the same region (e.g., Wessenstadt, 800–600 bc, or Jastorf, 600–300 bc).
Evidence from archaeological finds and place-names suggests that, while early Germanic peoples probably occupied much of northern Germany during the Bronze and early Iron ages, peoples speaking Celtic languages occupied what is now southern Germany. This region, together with neighbouring parts of France and Switzerland, was the original homeland of the Celtic La Tène culture. About the time of the Roman expansion northward, in the first centuries bc and ad, Germanic groups were expanding southward into present-day southern Germany. The evidence suggests that the existing population was gradually Germanized rather than displaced by the Germanic peoples arriving from the north.
Solid historical information begins about 50 bc when Julius Caesar’s Gallic Wars brought the Romans into contact with Germanic as well as Celtic peoples. Caesar did cross the Rhine in 55 and 53 bc, but the river formed the eastern boundary of the province of Gaul, which he created, and most Germanic tribes lived beyond it. Direct Roman attacks on Germanic tribes began again under Nero Claudius Drusus Germanicus, who pushed across the Rhine in 12–9 bc, while other Roman forces assaulted Germanic tribes along the middle Danube (in modern Austria and Hungary). Fierce fighting in both areas, and the famous victory of the Germanic leader Arminius in the Teutoburg Forest in ad 9 (when three Roman legions were massacred), showed that conquering these tribes would require too much effort. The Roman frontier thus stabilized on the Rhine and Danube rivers, although sporadic campaigns (notably under Domitian in ad 83 and 88) extended control over Frisia in the north and some lands between the Rhine and the upper Danube.
Both archaeology and Caesar’s own account of his wars show that Germanic tribes then lived on both sides of the Rhine. In fact, broadly similar archaeological cultures from this period stretch across central Europe from the Rhine to the Vistula River (in modern Poland), and Germanic peoples probably dominated all these areas. Germanic cultures extended from Scandinavia to as far south as the Carpathians. These Germans led a largely settled agricultural existence. They practiced mixed farming, lived in wooden houses, did not have the potter’s wheel, were nonliterate, and did not use money. The marshy lowlands of northern Europe have preserved otherwise perishable wooden objects, leather goods, and clothing and shed much light on the Germanic way of life. These bogs were also used for ritual sacrifice and execution, and some 700 “bog people” have been recovered. Their remains are so well preserved that even dietary patterns can be established; the staple was a gruel made of many kinds of seeds and weeds.
Clear evidence of social differentiation appears in these cultures. Richly furnished burials (containing jewelry and sometimes weapons) have been uncovered in many areas, showing that a wealthy warrior elite was developing. Powerful chiefs became a standard feature of Germanic society, and archaeologists have uncovered the halls where they feasted their retainers, an activity described in the Anglo-Saxon poem Beowulf. This warrior elite followed the cult of a war god, such as Tyr (Tiu) or Odin (Wodan). The Roman historian Tacitus relates in the Germania that in ad 59 the Hermunduri, in fulfillment of their vows, sacrificed defeated Chatti to one of these gods. This elite was also the basis of political organization. The Germanic peoples comprised numerous tribes that were also united in leagues centred on the worship of particular cults. These cults were probably created by one locally dominant tribe and changed over time. Tribes belonging to such leagues came together for an annual festival, when weapons were laid aside. Apart from worship, these were also times for economic activity, social interaction, and settling disputes. Coexistence with Rome to ad 350
After Rome had established its frontiers, commercial and cultural contacts between Germanic peoples and the Roman Empire were as important as direct conflict. Although it was heavily fortified, the frontier was never a barrier to trade or travel. About ad 50, tribes settled along the Rhine learned to use Roman money. Germanic graves—at least the richer ones—began to include Roman luxury imports such as fine pottery, glass, and metalwork. In return, raw materials, such as amber and leather, and many slaves went back across the frontier. Germanic tribesmen also served in Roman armies.
Border raiding was endemic, and periodically there were much larger disturbances. About ad 150 the Marcomanni, a Germanic tribe, moved south into the middle Danube region, and they even invaded Italy in 167. The emperor Marcus Aurelius and his son spent the next 20 years curbing their inroads, and archaeology shows that the wars were highly destructive. This migration was one manifestation of a broader problem, for between about 150 and 200 a whole series of Germanic groups moved south along the river valleys of central and eastern Europe. These migrations resulted in great violence along the entire frontier during the 3rd century. Parts of Gaul suffered greatly, and Goths, a Germanic people that originated in southern Scandinavia, ravaged the Danube region, even killing the emperor Decius in 251. Yet intensive campaigns brought the Germanic tribes back under control, so that by about 280 stability had returned to the Rhine and Danube. The Roman army and an alliance system involving, among others, Franks, Alemanni, and Goths maintained the frontier until about 370.
In the meantime the Germanic world was being transformed. For the balance of power in Europe, the most important development was the rise of larger and more cohesive Germanic political units, at least among the Germanic peoples living on the borders of the empire. This was largely a response to the military threat from Rome. Despite their occasional successes, more Germanic tribesmen than Romans had been killed in 3rd-century conflicts, and the Germanic peoples had learned that larger groups were more likely to survive. In the 4th century there were two powerful Germanic confederations: the Alemanni on the Rhine and the Goths on the Danube, both controlled by the military elite whose power over their fellow tribesmen continued to increase. Other contacts with the empire resulted in cultural borrowings. In the 3rd century Germanic peoples began to master the potter’s wheel, and there is evidence of improved farming techniques; both were adopted from Rome. The empire was also partly responsible for Germanic groups’ first steps toward literary culture. A written form of Gothic, the oldest literary Germanic language, was created about ad 350 by Ulfilas, a Roman-sponsored Arian Christian missionary, in order to translate the Bible.
