The Alemanni or Alamanni were a confederation of Germanic tribes on the Upper Rhine River during the first millennium. First mentioned by Cassius Dio in the context of the campaign of Roman emperor Caracalla of 213, the Alemanni captured the Agri Decumates in 260, and later expanded into present-day Alsace and northern Switzerland, leading to the establishment of the Old High German language in those regions, which by the eighth century were collectively referred to as Alamannia.
The Saxons, sometimes called the Old Saxons, were the Germanic people of "Old" Saxony which became a Carolingian "stem duchy" in 804, in what is now northern Germany.
The Suebi were a large group of Germanic peoples originally from the Elbe river region in what is now Germany and the Czech Republic. In the early Roman era they included many peoples with their own names such as the Marcomanni, Quadi, Hermunduri, Semnones, and Lombards. New groupings formed later, such as the Alamanni and Bavarians, and two kingdoms in the Migration Period were simply referred to as Suebian.
The Chatti were an ancient Germanic tribe whose homeland was near the upper Weser (Visurgis) river. They lived in central and northern Hesse and southern Lower Saxony, along the upper reaches of that river and in the valleys and mountains of the Eder and Fulda regions, a district approximately corresponding to Hesse-Kassel, though probably somewhat more extensive. They settled within the region in the first century BC. According to Tacitus, the Batavians and Cananefates of his time, tribes living within the Roman Empire, were descended from part of the Chatti, who left their homeland after an internal quarrel drove them out, to take up new lands at the mouth of the Rhine.
The Quadi were a Germanic people during the Roman era, who were prominent in Greek and Roman records from about 20 AD to about 400 AD. By about 20 AD they had a kingdom centred in the area of present-day western Slovakia, north of the Roman border on the Danube river. After probably first settling near the Morava river the Quadi expanded their control eastwards over time until they also stretched into present day Hungary. This was part of the bigger region which had been partly vacated a generation earlier by the Celtic Boii, and their opponents the Dacians. The Quadi were the easternmost of a series of four related Suebian kingdoms that established themselves near the river frontier after 9 BC, during a period of major Roman invasions into both western Germania to the northwest of it, and Pannonia to the south of it. The other three were the Hermunduri, Naristi, and the Quadi's powerful western neighbours the Marcomanni. Despite frequent difficulties with the Romans, the Quadi survived to become an important cultural bridge between the peoples of Germania to the north, the Roman Empire to the south, and the Sarmatian peoples, most notably the Iyzyges, who settled in the same period to their east in present day Hungary.
The Thuringii, or Thuringians were a Germanic people who lived in the kingdom of the Thuringians that appeared during the late Migration Period south of the Harz Mountains of central Germania, a region still known today as Thuringia. The Thuringian kingdom came into conflict with the Merovingian Franks, and it later came under their influence and Frankish control as a stem duchy. The name is still used for one of modern Germany's federal states (Bundesländer).
Germania, also more specifically called Magna Germania, Germania Libera, or Germanic Barbaricum to distinguish it from the Roman provinces of Germania Inferior and Germania Superior, was a historical region in north-central Europe during the Roman era, which was associated by Roman authors with the Germanic peoples. According to Roman geographers, this region stretched roughly from the Rhine in the west to the Vistula in the east, and to the Upper Danube in the south, and the known parts of southern Scandinavia in the north. Archaeologically, these people correspond roughly to the Roman Iron Age of those regions.
The Usipetes or Usipii were an ancient tribe who moved into the area on the right bank of the lower Rhine in the first century BC, putting them in contact with Gaul and the Roman empire. They are known first from the surviving works of ancient authors such as Julius Caesar and Tacitus. They appear to have moved position several times before disappearing from the historical record.
The Hermunduri, Hermanduri, Hermunduli, Hermonduri, or Hermonduli were an ancient Germanic tribe, who occupied an inland area near the source of the Elbe river, around what is now Bohemia from the first to the third century, though they have also been speculatively associate with Thuringia further north. According to an old proposal based on the similarity of the names, the Thuringii may have been the descendants of the Hermunduri. At times, they apparently moved to the Danube frontier with Rome. Claudius Ptolemy mentions neither tribe in his geography but instead the Teuriochaemae, who may also be connected to both.
The Semnones were a Germanic and specifically a Suebi people, located between the Elbe and the Oder in the 1st and 2nd centuries AD.
The Chamavi, Chamãves or Chamaboe (Χαμαβοί) were a Germanic tribe of Roman imperial times whose name survived into the Early Middle Ages. They first appear under that name in the 1st century AD Germania of Tacitus as a Germanic tribe that lived to the north of the Lower Rhine. Their name probably survives in the region today called Hamaland, which is in the Gelderland province of the Netherlands, between the IJssel and Ems rivers.
The Chasuarii were an ancient Germanic tribe known from the reports of authors writing in the time of the Roman Empire. They lived somewhere to the east and north of the Rhine, near the modern river Hase, which feeds into the Ems. This means they lived near modern Osnabrück.
The Angrivarii were a Germanic people of the early Roman Empire, who lived in what is now northwest Germany near the middle of the Weser river. They were mentioned by the Roman authors Tacitus and Ptolemy.
The Varini, Warni or Warini were one or more Germanic peoples who originally lived in what is now northeastern Germany, near the Baltic Sea.
The Dulgubnii are a Germanic tribe mentioned in Tacitus' Germania as living in what is today northwest Germany. Tacitus describes them being to the north of the Angrivarii and Chamavi, and as having moved from the north into the area once belonging to the Bructeri, between Ems, Lippe, and Weser. In this same area as the Dulgubnii, north of the Chamavi and Angrivarii, were the Chasuarii, and north of these, on the North Sea coast, where the Chauci. The Chasuarii's name is thought to derive from the River Hase which feeds into the middle of the Ems from the east, just northwest of the area associated with the Angrivarii, on the Weser. So from Tacitus, it appears that the Dulgubnii probably lived near the Weser.
The 'Baenochaemae, Bainochaimai were a Germanic people recorded only in the Geography of Claudius Ptolemy, who described them as living near the Elbe.
The Tencteri or Tenchteri or Tenctheri were an ancient tribe, who moved into the area on the right bank of the lower Rhine in the 1st century BC. They are known first from the surviving works of ancient authors such as Julius Caesar and Tacitus. In December 2015, archaeologists believed they found remains of the Tencteri in The Netherlands.
The Germani cisrhenani, or "Left bank Germani", were a group of Germanic peoples who lived west of the Lower Rhine at the time of the Gallic Wars in the mid-1st century BC.
The Elbe Germans or Elbe Germanic peoples were Germanic tribes whose settlement area, based on archaeological finds, lay either side of the Elbe estuary on both sides of the river and which extended as far as Bohemia and Moravia, clearly the result of a migration up the Elbe river from the northwest in advance of the main Migration Period until the individual groups ran into the Roman Danube Limes around 200 AD.
