The defeat of the Romans at the
Battle of Adrianople in 378 marked a turning point for the remaining Suebi on the Middle
Danube frontier, including the
Quadi and the
Marcomanni. The arrival of large numbers of armed
Huns,
Goths and
Alans disrupted the border region on both sides. At first, the Suebi of the Middle Danube who lived outside the empire are recorded as working with the newcomers from the east to raid Roman lands. After the death of emperor
Theodosius I in 395,
Saint Jerome listed the Marcomanni and Quadi and their old neighbours the Sarmatians and Vandals, together with several of the eastern peoples causing devastation in the Roman provinces stretching from
Constantinople to the
Julian Alps, including
Dalmatia, and all the provinces of
Pannonia: "Goths and Sarmatians, Quadi and Alans, Huns and Vandals and Marcomanni". The poet
Claudian describes this mass of people crossing the frozen Danube with wagons, and then setting wagons rigged around themselves like a wall at the approach of the Roman commander Stilicho. He says that all the fertile lands between the Black Sea and Adriatic were subsequently like uninhabited deserts, specifically including Dalmatia and Pannonia. The various peoples living upon the Middle Danube frontier did not remain united. There was conflict between the Alans, Huns and Goths, which led to massacres according to Orosius. The Huns under
Uldin began to dominate the region, and they helped the Romans suppress a large force which
Radagaisus gathered there to invade Italy in 406. There was also famine according to Isidore of Seville. Large numbers of people from the Middle Danube now headed far to the west, where they entered Roman Gaul during a period when the border was poorly defended. The last contemporary mention of the Quadi as an identifiable people is in another letter by Jerome from 409, but it places them far from home. He lists them first among the peoples who were occupying Gaul at that time: "Quadi, Vandals, Sarmatians, Alans, Gepids, Herules, Saxons, Burgundians, Alemanni and—alas for the commonwealth!—even Pannonians" (in other words Roman citizens from Pannonia). Apart from the Saxons, Burgundians and Alemanni, who were already well-known near the Rhine, the others are from the Middle Danube area.
The Kingdom of the Suevi in Hispania Many of the Suebi who came into Gaul around 406, probably including many Quadi, soon moved further west, into Hispania, where a large force of Suebi arrived by 409 AD, about the same time as large groups of Vandals and Alans. Hispania was at this time under the control of the rebel Roman general
Gerontius and the newcomers came to agreements with him as military allies in his struggle against Roman forces. The three groups proceeded to divide Hispania between themselves into four kingdoms, with the agreement of Gerontius. After the defeat of Gerontius, the Roman authorities rejected these agreements and the
Visigoths began to work against the four kingdoms. After many of the Vandals and Alans moved to
Carthage, the Suebi were the last of them to hold an independent kingdom, which endured until 585, when it was absorbed by the Visigothic kingdom. From 456/457 it was however already a vassal of the Visigoths.
The Hunnic alternative Some Danubian Suebi remained in the region which increasingly came under the control of the Huns, led at first by Uldin. A powerful Hunnic empire developed, giving the non-Roman peoples of the frontier an alternative way to improve their lives outside the empire.
Herwig Wolfram has referred to this as the "Hunnic alternative". Although they may have been present, in 451 none of the Suebian groups are listed by contemporary sources as taking part in the
Battle of the Catalaunian Plains, where the Roman allies under
Aetius defeated the allies of Attila the Hun.
Attila died in 453. In the ensuing period, a short-lived Suevian kingdom emerged as one of several new kingdoms with ethnic names in Pannonia and the Middle Danubian region. This kingdom was ruled at first by two kings named
Hunimund and Alaric. It existed in or near north-eastern Pannonia. It may have been made up of a mixture of peoples, although the Quadi were likely most prominent. After being defeated by the
Ostrogoths, another of the successor kingdoms, Hunimund and some of these Suebi seem to have moved west and joined the Alemanni. In 469/470 Jordanes reported that Suebi from the Middle Danube fled west into the Alps and joined the Alamanni there. However, their merged forces were defeated by their enemies from the Middle Danube, the Ostrogoths. The country where the Alamanni and Suabi lived is described by Jordanes in a way which gives a rough indication of the new peoples were developing: Bavarians to the east, Franks to the west, Burgundians to the south, and Thuringians to the north (). It is believed that this apparent merger of the Danubian Suebi and the Alamanni might explain why the Alamanni subsequently came to be called Swabians themselves in the Middle Ages.
The Alemanni and Juthungi In the period before 409, although they already lived near the Rhine, the Alemanni, like their neighbours the Burgundians, were caught up in the great movements westwards over the Rhine. It appears to be in this period that the Alemanni and Burgundians extended their territories westwards over the Rhine to include the present day
Rhineland-Palatinate and
Alsace. The exact territory of the Burgundians at this time is unknown, and they lost it in 436. By around 480 the Burgundians were placed to the south of the Alemanni and able to block their path south into present-day western Switzerland. To the west of the Alemanni, in 430 the Juthungi raided Raetia on the Danube, and were repelled by Aetius and his forces. This is the last time the Juthungi were mentioned as a distinct people. The Baiuvarii (early Bavarians) would later rule Raetia. In 470-476, a few years after Jordanes claims that Suebi from the east moved to live with the Alemanni,
Saint Severinus, near
Passau, negotiated the release of prisoners of war from an Alemannic king named Gibuldus. At almost the same time, Bishop
Lupus of Troyes negotiated the release of captives from his diocese of Troyes from an Alemannic king Gebavultus, possibly the same person. In the 490s one or more battles were fought between the Alemanni and the Franks. By 507 many of the Alemanni were under Frankish control, with another part under the protection of the Ostrogothic kings in Italy. In 537 the Ostrogoths ceded control of the rest of the Alemanni and also Raetia where the Bavarians were.
Roman Pannonia Other Middle Danubian Suebi moved southwards into Roman lands, including many Marcomanni.
Ambrose, bishop of Milan (374–397), corresponded with a Christian Marcomannic queen named
Fritigil, initiating a peace treaty between the Marcomanni and the western Roman military leader
Stilicho. That was the last clear evidence of the Marcomanni having a polity, which was probably now on the Roman side of the Danube, in Pannonia. The
Notitia Dignitatum lists several Marcomanni units among the surviving Roman military forces posted around the empire. After the death of Attila, the stretch of the Danube between Passau and Vienna was ruled by the Rugii, but there were still Roman forts and towns, as described by
Eugippius in his writings about the times of
Severinus of Noricum. Soon afterwards, in 488, these Rugii were defeated by
Odoacer the king of Italy and after some years under the control of the
Heruli, the Langobards, a Suebian who had recently migrated from the northern part of the Elbe, took control of the region and began expanding their Pannonian territory to the south. The
Ravenna Cosmography, a much later document which used sources that are in many cases now lost, indicates that a
Marcannori people (
Marcannorum gens) lived in the mountainous southwest of Pannonia near the
Sava river. A Sava or
Suavia province between the Sava and
Drava rivers continued to exist during the time when the
Ostrogoths ruled Italy, and may have been named after these Suebi (Suavi). It is possible that the Suebi moved into this more southern area after the defeat of Hunimund, or they may have been a separate group. During the Ostrogothic period, these Suebi were legally distinguished from the native populations under the term "old barbarians" (
antiqui barbari), which also distinguished them from the new arrivals, the Goths. Unusually, they were legally permitted to marry provincial residents and could therefore become part of the land-owning class. Some scholars believe these were descendants of the Christian Marcomanni of Queen Fritigil. During the time of
Theoderic the Great a group of Alemanni crossed the Alps with cattle and wagons to seek refuge with these
antiqui barbari.
Procopius noted that in 537 the
Ostrogoths recruited an army of these Suebi to launch an attack against areas held by the Eastern Roman empire. In 540 Ostrogothic rule in the Sava region came to an end, and the Suebi came under the authority of the Eastern Roman emperor
Justinian. Many of the Suebi who remained in the Pannonian region are believed to have taken up a Lombardic identity after the defeat of the Ostrogoths, and many may therefore have subsequently entered Italy with the Suebian Lombards. The region subsequently came under the control of the
Pannonian Avars, and it is probably during this period that
Slavic languages eventually became dominant in the areas where the Quadi had lived.
Integration into the Lombards Many Suebi from the Danubian region were assimilated into the Langobards (Lombards), who had themselves long ago been counted among the Suebian peoples in first and second century Roman ethnography. In the 6th century, the Langobards were no longer referred to as Suebi, but they apparently absorbed Suebi during their time in the Middle Danubian, including some from the southern
Suavian part of Pannonia. When the Lombards entered
Italy after 568, Suebi were among the groups who joined them, and formed part of their realm in Italy.
Suebi who remained in the north Despite all these changes, there are indications that at least one group of Suebi, the so-called "northern Suebi", seem to have survived near their Elbe homelands into the Middle Ages. • The Frankish king
Theudebert I (534–547) wrote to the Byzantine emperor
Justinian boasting that at the start of his reign in 534 the Frankish kingdom extended "from the Danube and the frontiers of Pannonia to the northern Ocean". The subjects peoples living north of the Danube were listed as the
Thuringians, North Swabians (
Norsavi), Saxons, and the
Eucii, who were perhaps identical with the
Jutes. •
Venantius Fortunatus named Suebi alongside
Frisians. • The
Old English Widsith mentions
Swaefe located in what is now
Schleswig-Holstein. •
Widukind of Corvey mentioned the
Suavi Transbadani. • Later, 10th–11th century evidence records a “Schwabengau” north of the
Harz regions, though the origin of this name cannot be securely explained. • The “North Suebi” are also mentioned in the
Annals of Metz.
The Bavarians Between the Alemanni and the Langobards, in what had been Roman
Raetia, a new people named the Baiuvarii appeared by the 6th century, and these were the forerunners of the medieval Bavarians. Although they were never referred to as Suebi, modern scholars often mention them among the "Elbe Germanic peoples" who supposedly carried a Suebian culture. While their origins are unclear, scholars believe their language and material culture was difficult to distinguish from the Alemanni or Langobards. Jordanes mentioned the Baiuvarii in his account of 5th century events, but the relatively detailed biography of
Severinus of Noricum describes the region around Passau being affected by Alemanni, Thuringians, and Rugii, and never mentions the Baiuvarii. They became important soon after the defeat of the Rugii by
Odoacer in 488, who was at that time the ruler of Roman Italy. To the east of the early Baiuvarii, the power vacuum created by the subsequent movements of armed peoples to Italy was filled the Suebian
Langobards who had moved southwards from the Elbe in this period. Raetia however remained relatively Romanized for some time, and Bavaria continued to have Romance speakers into the Middle Ages. Traditionally, discussion about the origins of the Baiuvarii starts with their name, which indicates a connection to one of the regions once inhabited by the
Boii. It implies that some of the early Bavarians moved from one or more of the regions to the east of Bavaria. This could include the Roman province of
Noricum, which was previously associated with the Marcomanni and their neighbours, and later with Hunnic allies such as the Rugii. Like the Swabians in Alamannia, in the
Middle Ages Bavaria became a
stem duchy in the
Holy Roman Empire. ==Norse mythology==
