The Huns were a nomadic people who lived in Central Asia, the Caucasus, and Eastern Europe between the 4th and 6th centuries CE. They were first reported living east of the Volga River, in an area that was part of Scythia at the time. By 370 CE, the Huns had arrived on the Volga, causing the westward movement of Goths and Alans. By 430, they had established a vast, but short-lived, empire on the Danubian frontier of the Roman empire in Europe. Several central and eastern European peoples seem to have maintained kingdoms under Hunnic hegemony, including not only the recently arrived Amali-led Goths, but also Gepids, Sarmatians, Heruli, Suebi, Sciri, and Rugii, who were all already associated with the Carpathian-Danubian region before the Huns arrived.

The Huns, especially under their King Attila, made frequent and devastating raids into the Eastern Roman Empire. In 451, they invaded the Western Roman province of Gaul, where they fought a combined army of Romans and Visigoths at the Battle of the Catalaunian Fields, and in 452, they invaded Italy. After the death of Attila in 453, the Huns ceased to be a major threat to Rome and lost much of their empire following the Battle of Nedao (c. 454). Descendants of the Huns, or successors with similar names, are recorded by neighboring populations to the south, east, and west as having occupied parts of Eastern Europe and Central Asia from about the 4th to 6th centuries. Variants of the Hun name are recorded in the Caucasus until the early 8th century.
In the 18th century, French scholar Joseph de Guignes became the first to propose a link between the Huns and the Xiongnu people, who lived in Mongolia and northern China from the 3rd century BCE to the late 1st century CE. Since Guignes's time, considerable scholarly effort has been devoted to investigating such a connection. The issue remains controversial, but recent archaeogenetic studies show some Hun-era individuals to have DNA similar to populations in ancient Mongolia. Their relationships with other entities, such as the Iranian Huns and the Huna people who invaded the Indian subcontinent, have also been disputed.
Very little is known about Hunnic culture, and very few archaeological remains have been conclusively associated with the Huns. They are believed to have used bronze cauldrons and to have performed artificial cranial deformation. No description exists of the Hunnic religion at the time of Attila, but practices such as divination are attested, as well as the likely existence of shamans. It is also known that the Huns had a language of their own; however, only three words and personal names attest to it.
Economically, the Huns are known to have practiced a form of nomadic pastoralism. As their contact with the Roman world grew, their economy became increasingly tied with Rome through tribute, raiding, and trade. They do not seem to have had a unified government when they entered Europe but rather to have developed a unified tribal leadership in the course of their wars with the Romans. The Huns ruled over a variety of peoples who spoke numerous languages, and some maintained their own rulers. Their main method of warfare was mounted archery.
The Huns may have initiated the Great Migration, a contributing factor in the collapse of the Western Roman Empire. The memory of the Huns also lived on in the hagiographies of various Christian saints, where the Huns play the role of antagonist, as well as in Germanic heroic legend, where the Huns are variously the antagonists or allies of the main Germanic figures. In Hungary, a legend developed based on medieval chronicles that the Hungarians, and in particular the Székely ethnic group, are descended from the Huns. However, mainstream scholarship has dismissed a close connection between the Hungarians and Huns. Modern culture generally associates the Huns with extreme cruelty and barbarism and is intertwined with the Mongol Empire.
Origin
The origins of the Huns and their links to other steppe people remain uncertain: they likely originated in Central Asia but their origins are disputed. Classical sources assert that they appeared in Europe suddenly around 370.
Roman-era sources
Most typically, Roman writers' attempts to elucidate the origins of the Huns simply equated them with earlier steppe peoples. Roman writers repeated a tale that the Huns had entered the domain of the Goths while they were pursuing a wild stag, or else one of their cows that had escaped, across the Kerch Strait into Crimea. Discovering the land fertile, they then attacked the Goths. Jordanes's Getica relates that the Goths held the Huns to be offspring of "unclean spirits" and Gothic witches (Getica 24:121).
Relation to the Xiongnu and other peoples called Huns
Since Joseph de Guignes in the 18th century, modern historians have associated the Huns who appeared on the borders of Europe in the 4th century CE with the Xiongnu who had invaded numerous Central Plain polities from the Mongolian Plateau between the 3rd century BCE and the 2nd century CE. After the devastating defeat by the Han dynasty, the northern branch of the Xiongnu retreated north-westward; their descendants may have migrated through the Eurasian Steppe and consequently they may have some degree of cultural and genetic continuity with the Huns. Scholars also discussed the relationship between the Xiongnu, the Huns, and a number of people in central Asia who were also known as or came to be identified with the name "Hun" or "Iranian Huns". The most prominent of these were Chionites, the Kidarites, and the Hephthalites.
Otto J. Maenchen-Helfen was the first to challenge the traditional approach, based primarily on the study of written sources, and to emphasize the importance of archaeological research. Since Maenchen-Helfen's work, the identification of the Xiongnu as the Huns' ancestors has become controversial. Additionally, several scholars have questioned the identification of the "Iranian Huns" with the European Huns. Walter Pohl cautions that
none of the great confederations of steppe warriors was ethnically homogenous, and the same name was used by different groups for reasons of prestige, or by outsiders to describe their lifestyle or geographic origin. [...] It is therefore futile to speculate about identity or blood relationships between H(s)iung-nu, Hephthalites, and Attila's Huns, for instance. All we can safely say is that the name Huns, in late antiquity, described prestigious ruling groups of steppe warriors.
As of October 2026, there is no general consensus on the issue of a Hun–Xiongnu connection. Recent supporters of a connection between the Huns and Xiongnu include Hyun Jin Kim and Etienne de la Vaissière. De la Vaissière argues that ancient Chinese and Indian sources used Xiongnu and Hun to translate each other, and that the various "Iranian Huns" were similarly identified with the Xiongnu. Kim believes that the term Hun was "not primarily an ethnic group, but a political category" and argues for a fundamental political and cultural continuity between the Xiongnu and the European Huns, as well as between the Xiongnu and the "Iranian Huns".
Etymology
The name Hun is attested in classical European sources as Greek Οὖννοι (Ounnoi) and Latin Hunni or Chuni. John Malalas records their name as Οὖννα (Ounna). Another possible Greek variant may be Χοὖνοι (Khounoi), although this group's identification with the Huns is disputed. Classical sources also frequently use the names of older and unrelated steppe nomads instead of the name Hun, calling them Massagetae, Scythians, and Cimmerians, among other names.
The etymology of Hun is unclear. Various proposed etymologies generally assume at least that the names of the various Eurasian groups known as Huns are related. There have been a number of proposed Turkic etymologies, deriving the name variously from Turkic ön, öna (to grow), qun (glutton), kün, gün, a plural suffix "supposedly meaning 'people'", qun (force), and hün (ferocious). Maenchen-Helfen dismisses all of these Turkic etymologies as "mere guesses" and proposes an Iranian etymology, from a word akin to Avestan hūnarā (skill), hūnaravant- (skillful). He suggests that it may originally have designated a rank rather than an ethnicity. Robert Werner has advanced an etymology from Tocharian ku (dog), suggesting—as the Chinese called the Xiongnu dogs—that the dog was the totem animal of the Hunnic tribe. He also compares the name Massagetae, noting that the element saka in that name means dog. Others such as Harold Bailey, S. Parlato, and Jamsheed Choksy have argued that the name derives from an Iranian word akin to Avestan Ẋyaona, and was a generalized term meaning "hostiles, opponents". Christopher Atwood dismisses this possibility on phonological and chronological grounds. While not arriving at an etymology per se, Atwood derives the name from the Ongi River in Mongolia, which was pronounced the same as, or similarly to, the name Xiongnu, and suggests that it was originally a dynastic name rather than an ethnic name.
Physical appearance
Most of the ancient descriptions of the Huns stress their strange appearance from a Roman perspective. These descriptions typically caricature the Huns as monsters. Jordanes stresses that the Huns were short of stature, had tanned skin and round and shapeless heads. Various writers mention that the Huns had small eyes and flat noses. The Roman writer Priscus gives the following eyewitness description of Attila: "Short of stature, with a broad chest and a large head; his eyes were small, his beard thin and sprinkled with grey; and he had a flat nose and tanned skin, showing evidence of his origin."
Many scholars take these to be unflattering depictions of East Asian (obsolete "Mongoloid") racial characteristics. Maenchen-Helfen argues that, while many Huns had East Asian racial characteristics, they were unlikely to have looked as Asiatic as the Yakut or Tungus. He notes that archaeological finds of presumed Huns suggest that they were a racially mixed group containing only some individuals with East Asian features. Kim similarly cautions against seeing the Huns as a homogenous racial group, while still arguing that they were "partially or predominantly of Mongoloid extraction (at least initially)." Some archaeologists have argued that archaeological finds have failed to prove that the Huns had any "Mongoloid" features at all, and some scholars have argued that the Huns were predominantly "Caucasian" in appearance. Other archaeologists have argued that "Mongoloid" features are found primarily among members of the Hunnic aristocracy, which, however, also included Germanic leaders who were integrated into the Hun polity. Kim argues that the composition of the Huns became progressively more "Caucasian" during their time in Europe; he notes that by the Battle of Chalons (451), "the vast majority" of Attila's entourage and troops appears to have been of European origin, while Attila himself seems to have had East Asian features.
Genetics
Genetic data is difficult to apply to steppe nomad societies, because they frequently migrated, intermixed, and were assimilated into each other. Genetics can still supply information on migrations from East Asia to Europe and vice versa.
In a genetic study of individuals from around the Tian Shan mountains of central Asia dating from the late second century CE, Damgaard et al. 2018 found that these individuals represented a population of mixed East Asian and West Eurasian origin. They argued that this population descended from Xiongnu who expanded westward and mixed with Iranian Sakas. This population in the Tian Shan mountains may be connected to the European Huns by individual burials that contains objects stylistically related to those used by the European Huns, although this could be a sign of the exchange of goods and the connections between elites rather than a sign of migration.
As of 2023, there is little genetic data from the Carpathian basin in the Hunnic period (5th century), and the population living there during the Hunnic period shows a variety of genetic signatures. Maróti et al. 2022 showed that the genomes of nine Hun-era individuals who lived in the basin varied from European to Northeast Asian connections, with those individuals showing associations with Northeast Asia being most similar to groups found in Mongolia such as the Xiongnu and the Xianbei. An analysis of Hun-era genomes by Gnecchi-Ruscone et al. 2022 likewise found a wide range of genetic variability, with two individuals showing a connection to ancient Northeast Asians and others showing European ancestry.
History
Before Attila
The history of the Huns in the fourth century is unclear, and the Huns left no sources themselves. The Romans became aware of the Huns when the latter's invasion of the Pontic steppes forced thousands of Goths to move to the Lower Danube to seek refuge in the Roman Empire in 376. The Huns conquered the Alans, most of the Greuthungi or Eastern Goths, and then most of the Thervingi or Western Goths, with many fleeing into the Roman Empire. In 395 the Huns began their first large-scale attack on the Eastern Roman Empire. Huns attacked in Thrace, overran Armenia, and pillaged Cappadocia. They entered parts of Syria, threatened Antioch, and passed through the province of Euphratesia. At the same time, the Huns invaded the Sasanian Empire. This invasion was initially successful, coming close to the capital of the empire at Ctesiphon; however, they were defeated badly during the Persian counterattack.
During their brief diversion from the Eastern Roman Empire, the Huns may have threatened tribes further west. Uldin, the first Hun identified by name in contemporary sources, headed a group of Huns and Alans fighting against Radagaisus in defense of Italy. Uldin was also known for defeating Gothic rebels who troubled the East Romans around the Danube and for beheading the Goth Gainas around 400–401. The East Romans began to feel the pressure from Uldin's Huns again in 408. Uldin crossed the Danube and pillaged Thrace. The East Romans tried to buy off Uldin, but his sum was too high so they instead bought off Uldin's subordinates. This resulted in many desertions from Uldin's group of Huns. Uldin himself escaped back across the Danube, after which he is not mentioned again in history.
Hunnish mercenaries are mentioned on several occasions being employed by the East and West Romans, as well as the Goths, during the late 4th and 5th century. In 433 some parts of Pannonia were ceded to them by Flavius Aetius, the magister militum of the Western Roman Empire.
Under Attila
From 434 the brothers Attila and Bleda ruled the Huns together. Attila and Bleda were as ambitious as their uncle Rugila. In 435 they forced the Eastern Roman Empire to sign the Treaty of Margus, giving the Huns trade rights and an annual tribute from the Romans. When the Romans breached the treaty in 440, Attila and Bleda attacked Castra Constantias, a Roman fortress and marketplace on the banks of the Danube. War broke out between the Huns and Romans, and the Huns overcame a weak Roman army to raze the cities of Margus, Singidunum and Viminacium. Although a truce was concluded in 441, two years later Constantinople again failed to deliver the tribute and war resumed. In the following campaign, Hun armies approached Constantinople and sacked several cities before defeating the Romans at the Battle of Chersonesus. The Eastern Roman Emperor Theodosius II gave in to Hun demands and in autumn 443 signed the Peace of Anatolius with the two Hun kings. Bleda died in 445, and Attila became the sole ruler of the Huns.
