The Heruli (or Herules) were an early Germanic people. Possibly originating in Scandinavia, the Heruli are first mentioned by Roman authors as one of several "Scythian" groups raiding Roman provinces in the Balkans and Aegean, attacking by land, and notably also by sea. During this time they reportedly lived near the Sea of Azov.
From the late 4th century AD the Heruli were one of the peoples dominated by the empire of Attila the Hun. By 454, after the death of Attila, they established their own kingdom on the Middle Danube, and Heruli also participated in successive conquests of Italy by Odoacer, Theoderic the Great, Narses and probably also the Lombards. Their independent kingdom was however destroyed by the Lombards in the early 6th century AD. A part of this population subsequently became established inside the Roman empire near Belgrade, and continued contributing fighting men to the Eastern Roman empire, and participating in Balkan and Italian conflicts.
With their last kingdom eventually dominated by Rome, and smaller groups integrated into larger political entities, the Heruli disappeared from history around the time of the conquest of Italy by the Lombards.
The name of the Heruli is sometimes spelled as Heruls, Herules, Herulians or Eruli. In the earliest mentions of them in 4th century records, they are called Eluri instead, leading to some doubts about whether they were the same people.
The name Heruli was often written without "h" in Greek (Έρουλοι, 'Erouloi') and Latin (Eruli), and is sometimes thought to be Germanic and related to the English word earl (see erilaz) implying that it was an honorific military title. There is even speculation that the Heruli were not a normal tribal group but a brotherhood of mobile warriors, though there is no consensus for this old proposal, which is based only on the name etymology and the reputation of Heruli as soldiers.
The Heruli are believed to have been Germanic-speaking. Personal names provide important evidence on the language of the Heruli. A large number of Heruli names are attested, and many of these are certainly Germanic, being similar to Gothic names.
The Heruli are specifically believed to have spoken an East Germanic language. These languages were also spoken by the Goths, Burgundians, Rugii, Vandals, Gepids and others. It has however also been proposed that they spoke a North Germanic language.
When first mentioned by Roman authors in the 3rd century AD, the Heruli were referred to as "Scythians", along with the Goths and allied tribes. The use of this term for Heruli and Goths probably began as early as Dexippus, whose work is now lost. The term does not imply any specific ethnic classification.
In late antiquity, the Gepids, Vandals, Rugii, Scirii, the non-Germanic Alans and the actual Goths, were all classified by Roman ethnographers as "Gothic" peoples, and modern historians generally consider the Heruli to be one of these. While historians such as Walter Goffart have pointed out that the Herules are never included in the lists of "Gothic peoples" of Procopius, Mihail Zahariade has shown that the Latin and Greek sources not only distinguish the Heruli (Elouroi in this period) from the Goths during their first 3rd century seaborne offensive (see below), but also Zonaras specifically stated that the Heruli were of Gothic stock — a categorization implied by other chroniclers of those events when they refer to Goths.
None of these eastern peoples were considered Germanic by Roman ethnographers at the time. However, in modern scholarship the Heruli are usually classified as a Germanic people. On account of having likely spoken an East Germanic language, the Heruli are often more specifically classified as an East Germanic people.
In his 6th century work Getica, the historian Jordanes, based in Constantinpole, wrote that the Heruli had been driven out of their homeland in Scandinavia by the Danes. This has been read as implying Heruli origins in the Danish isles or southernmost Sweden. The reliability and correct interpretation of this passage in the Getica is however disputed. On the other hand, his contemporary Procopius recounted a migration of a 6th-century group of Heruli noblemen to Thule (which for him, but not Jordanes, was the same as Scandinavia), from their "homeland" on the Middle Danube. Later, Danubian Heruli found new royalty among these northern Heruli. This account has been seen as implying an old and continuous connection between the Heruli and Scandinavia, although some recent scholars are skeptical of this interpretation, and have noted that Procopius does not depict the Heruli as returning to a homeland, but as leaving their homeland.
Ellegård has proposed that the Danish expulsion of the Heruli might have happened in the 6th century, and been an expulsion of the immigrants from the Danube: "the only thing we can say with reasonable certainty is that a small group of Eruli lived there for some 38-40 years in the first half of the sixth century A.D". He proposes that the evidence makes it most likely that "a loose group of Germanic warriors which came into being in the late third century in the region north of the Danube limes that extends roughly from Passau to Vienna".
On the Pontic steppe
The Heruli are believed to have migrated towards the region north of the Black Sea in the 3rd century AD. Other Germanic peoples, such as the Rugii and the Goths, are believed to have carried out a similar migration at this time. These peoples replaced the Sarmatians as the dominant power north of the Black Sea. The Sarmatians had in the 1st century AD replaced the Bastarnae, who are believed to have been a Germanic people. The arrival of the Heruli has been seen as part of a bigger cultural shift in this region, involving the migration from the northwest of Germanic peoples, who replaced the Sarmatians as the dominant power in the region.
The first relatively clear mention of the Heruli by Graeco-Roman writers concerns two major campaigns into the Balkans of 267/268 and 269/270. Goths, Heruli (referred to as "Eluri", Ἔλουροι, in the oldest sources), and other "Scythian" peoples from the region of the Sea of Azov, took control of Black Sea Greek cities, and gained a fleet that they used to launch raids along the northern Black Sea and as far as Greece and Asia Minor. These invasions began in the reign of Gallienus (260-268 AD), and continued until at least 269 during the reign of Marcus Aurelius Claudius, who subsequently took up the title "Gothicus" due to his victory.
In 267, Heruli (Αἴρουλοι) commanded a naval attack from the Sea of Azov, past the Danube delta, and into the straits of the Bosphorus where they took control of Byzantion and Chrysopolis, both near Constantinople itself. They then retreated to the Black sea, before returning, raiding Cyzicus and then entering the Aegean sea where they troubled Lemnos, Skyros and Imbros, before landing near Sparta and plundering the Peloponnese, including not only Sparta, but also Corinth, Argos, and the sanctuary of Zeus at Olympia. Still within 267 they reached Athens, where local militias had to defend the city. It seems to have been the Heruli specifically who sacked Athens despite the construction of a new wall, during Valerian’s reign only a generation earlier. This was the occasion for a famous defense made by Dexippus, whose writings were a source for later historians.
Further north, in 268, Gallienus defeated Heruli at the river Nestos using a new mobile cavalry, but as part of the surrender a Herulian chief named Naulobatus became the first barbarian known from written records to receive imperial insignia from the Romans, gaining the rank of a Roman consul. It is highly likely that these defeated Heruli were then made part of the Roman military.
Recent researchers such as Steinacher now have increased confidence that there was a distinct second campaign which began in 269, and ended in 270. Later Roman writers reported that thousands of ships left from the mouth of the Dnieper, manned by a large force of various different Scythian peoples, including Peuci, Greutungi, Austrogothi, Tervingi, Vesi, Gepids, Celts, and Heruli. These forces divided into two parts in the Hellespont. One force attacked Thessaloniki, and against this group the Romans, led by Claudius now, had a major victory at the Battle of Naissus (Niš, Serbia) in 269. This was apparently a distinct battle from that at the Nessos. A Herulian chieftain named Andonnoballus is said to have switched to the Roman side, and this was once again a case where Heruli appear to have joined the Roman military. The second group sailed south and raided Rhodes, Crete, and Cyprus and many Goths and Heruli managed to return safely to harbor in the Crimea. Lesser attacks continued until 276.
The Heruli are believed to have formed part of the Chernyakhov culture, which, although dominated by the Goths and other Germanic peoples, also included Bastarnae, Dacians and Carpi. The Heruli are thus archaeologically indistinguishable from the Goths.
Jordanes reports that the Heruli in the late 4th century AD were conquered by Ermanaric, king of the Greuthungian Goths. Ermanaric's realm may also have included Finns, Slavs, Alans and Sarmatians. Before being conquered by Ermanaric, Jordanes says that the Heruli were lead by their king Alaric. Herwig Wolfram has suggested that the future Visigothic king Alaric I may have been named after this Herulian king.
Doubts have been raised about this earliest, Black Sea period in the history of the Heruli. The first author known to have equated these "Eruli" with the later "Eruli" was Jordanes, in the 6th century.
The "western" Heruli, soldiers and pirates
The proposal that there may have been a Western kingdom of Heruli has posed a problem for scholars. This question arises because of the evidence of Heruli activity in the western Roman empire. The existence of this western kingdom is increasingly doubted.
Heruli were already seen in western Europe before the empire of Attila, at the time of their first ambitious campaigns in the east. In 268 Claudius Mamertinus reported the victory of Maximian over a group of Heruli and Chaibones (known only from this one report[a]) attacking Gaul.
It is believed that it was from this time that the Romans instituted a Herulian auxiliary unit, the Heruli seniores, who were stationed in northern Italy. This numerus Erulorum was a lightly-equipped unit often associated with the Batavian Batavi seniores. In 366 the Batavians and Heruli fought against Alamanni near the Rhine, under the leadership of Charietto who died in the battle, and then against Picts and Scoti in Britain. They were subsequently sent to fight Parthians in the east.
In 405 or 406, a large number of barbarian groups crossed the Rhine, entering the Roman empire, and the Heruli appear in the list of peoples given by the historian Jerome. However this list is sometimes thought to have drawn on historical lists for literary effect.
Later mentions of Heruli in western incidents where they were not clearly connected to the Roman military include two sea raids in northern Spain in the 450s, and the presence of Heruli at the Visigothic court of Euric in about 475. The raids were reported by Hydatius. Sidonius Apollinaris mentions Heruli at the Visigothic court in 476, although this is in a poetic letter. Recent scholars such as Steinacher and Halsall have pointed out that this type of evidence is consistent with the internal military conflicts that were happening in the Roman empire during this period. Halsall for example writes that it "must at least be a possibility that their raid constituted part of a Romano-Visigothic offensive against the Sueves" who had been part of an invasion of the same area. Steinacher demonstrates using examples from the period, including Charietto's life story, that barbarian soldiers could switch from being Roman soldier, to pirate, and back to soldier.
The Greek poet Sidonius Apollinaris specifically imagined the Heruli he saw at Euric's court as Oceanic sea-farers, but Steinacher argues that this raiding by sea was simply a logical strategy for Visigothic campaigns against the Iberian Suevi, and difficult to use as a proof that the Heruli had a coastal kingdom somewhere in the north.
In reality, there is nothing special about attacks from the sea: various marauders employed such tactics at various points in history. It is just easier and not too dangerous.
Given the writing style of Sidonius this reference could also be "nothing more than a bookish reference to third-century accounts of Herules attacking from the sea".
Kingdom on the Middle Danube
In the early 5th century AD, large groups of peoples left the Middle Danube region, including the groups who crossed the Rhine in 405, many of whom eventually reached Iberia. Others crossed the Danube, like the forces of Radagaisus, who invaded Italy. During this period, the Huns and their allies begin to be found in this same area instead, having crossed the Carpathians from the east. By 450 AD, the Heruli were firmly part of the Hunnic empire of Attila. The Gepids, Rugi, Scirii and many Goths, Alans and Sarmatians were also part of Attila's empire. They were among the peoples who are reported as having fought for Attila at the Battle of the Catalaunian Plains.
After the death of Attila, his sons lost power over the various peoples of his empire at the Battle of Nedao in 454. The centre of this alliance was now settled upon the Roman border north of the Middle Danube. Heruli who were possibly on the winning side with the Gepids, were subsequently among the several peoples now able to form a kingdom in that area. The Herulian kingdom, was established north of modern Vienna and Bratislava, near the Morava river, and possibly extending as far east as the Little Carpathians. They ruled over a mixed population including Suevi, Huns and Alans. Compared to other Middle Danubian kingdoms in this period, Peter Heather has described this Heruli kingdom as "middle-sized", similar to the Rugian one, but "clearly not as militarily powerful, say, as the Gothic, Lombard, or Gepid confederations which generated much longer-lived political entities, and into which elements of the Rugi and Heruli were eventually absorbed".
From this region the life story of Severinus of Noricum reports that the Heruli attacked Ioviaco near Passau in 480. The Heruli do not appear in early lists of Odoacer's allies after Nedao, but benefited from the downfall of his people the Scirii. They established control on the Roman (south) side of the Danube, north of Lake Balaton in modern Hungary when they were apparently able to take over the kingdoms of the Suevi and Scirii, who had been under pressure from the Ostrogoths, who continued to press their old allies from the south.
Odoacer, the commander of the Imperial foederati troops who deposed the last Western Roman Emperor Romulus Augustus in 476 AD came to be seen as king over several of the Danubian peoples including the Heruli, and the Heruli were strongly associated with his Italian kingdom. The Heruli on the Danube also took control of the Rugian territories, who had become competitors to Odoacer and been defeated by him in 488. However Heruli suffered badly in Italy, as loyalists of Odoacer, when he was defeated by the Ostrogoth Theoderic.
By 500 the Herulian kingdom on the Danube, apparently by now under a king named Rodulph, had made peace with Theoderic and become his allies. Paul the Deacon also mentions Heruli living in Italy under Ostrogothic rule. Peter Heather estimates that the Herulian kingdom could muster an army of 5,000-10,000 men.
Theoderic's efforts to build a system of alliances in Western Europe were made difficult both by counter diplomacy, for example between Merovingian Franks and the Byzantine empire, and also the arrival of a new Germanic people into the Danubian region, the Lombards who were initially under Herule hegemony. The Herulian king Rodulph lost his kingdom to the Lombards at some point between 494 and 508.
After the Middle Danubian Herulian kingdom was destroyed by the Lombards in or before 508, Herulian fortunes waned. According to Procopius, in 512 a group including royalty went north and settled in Thule, which for Procopius meant Scandinavia. Procopius noted that these Heruli first traversed the lands of the Slavs, then empty lands, and then the lands of the Danes, until finally settling down nearby the Geats. Peter Heather considers this account to be "entirely plausible" although he notes that others have labelled it a "fairy story", and given that it only appears in one source it is possible to deny its validity.
What happened to the main part of the Danubian Heruli has been difficult to reconstruct from Procopius, but according to Steinacher they first moved downstream on the Danube to an area where the Rugii had sought refuge in 488. Here they suffered famine. They sought refuge among the Gepids, but wanting to avoid being mistreated by them crossed the Danube came under East Roman authority.
Anastasius Caesar allowed them to resettle depopulated "lands and cities" in the empire in 512. Modern scholars debate whether they were moved then to Singidunum (modern Belgrade), or first to Bassianae, and to Singidunum some decades later, by Justinian. This area had been re-acquired by the empire from the Goths, who now ruled Italy from Ravenna. Justinian integrated them into the empire as a buffer between the Romans and the more independent Lombards and Gepids to the north. Under his encouragement, the Herule king Grepes converted to Orthodox Christianity in 528 together with some nobles and twelve relatives. Procopius who felt that this made them somewhat gentler, also showed in his account of the wars against the African Vandals, that some of them were Arian christians.
The Heruli were often mentioned during the times of Justinian, who used them in his extensive military campaigns in many countries including Italy, Syria, and North Africa. Pharas was a notable Herulian commander during this period. Several thousand Heruli served in the personal guard of Belisarius throughout the campaigns, and Narses also recruited from them. They were a participant in the Byzantine-Sasanian wars, such as the Battle of Anglon.
Grepes and most of his family had apparently died by the early 540s, possibly in the Plague of Justinian (541-542). Procopius related that in the 540s the Heruli who had been settled in the Roman Balkans killed their own king Ochus and, not wanting the one assigned by the emperor, Suartuas, they made contact with the Heruli who had gone to Thule decades earlier, seeking a new king. Their first choice fell sick and died when they had come to the country of the Dani, and a second choice was made. The new king Datius arrived with his brother Aordus and 200 young men. The Heruli who were sent against Suartuas defected with him and were supported by the empire. The supporters of Datius, two thirds of the Heruli, submitted to the Gepids. This period of rebellion against Rome lasted approximately 545-548, the period immediately before conflict between their larger neighbours the Gepids and Lombards broke out, but this rebellion was repressed by Justinian.
In 549, when the Gepids fought the Romans, and Heruli fought on both sides. In any case after one generation in the Belgrade area, the Herulian federate polity in the Balkans disappears from the surviving historical records, apparently replaced by the incoming Avars.
Peter Heather has written that:
by c.540 being a Herule had ceased to be the main determinant of individual behaviour; the Heruli had ceased to operate together on the basis of that shared heritage, and different Heruli were adopting different strategies for survival in the new political conditions which even caused them to fight on opposing sides. After c.540, we still find small groups called Heruli fighting for the East Romans in Italy, and it is noticeable that the Roman commanders were careful to appoint for them leaders of their own race. Thus some sense of identity probably remained. That said, we are clearly dealing with a few fragments of the original group, and, in the prevailing circumstances, Herule identity had no future.
Sarantis however shows that the Belgrade-region Heruli continued to be recruited, and to play a role in local conflicts involving the Gepids and Lombards, into the 550s. Suartas, a Herule general for the Romans, led Herule forces against the Gepids in 552 for example. However it appears that by this period the semi-independent Heruli near Belgrade became Roman provincials.
In 566, Sinduald, a Herule military leader under Narses, was declared a king of Heruli in Trentino in northern Italy, but he was executed by Narses. Sinduald was said to be a descendant of the Herules who had already entered Italy under Odoacer.
The early religion of the Heruli is vividly described by Procopius in his History of the Wars. He describes them as a polytheistic society known to practice human sacrifice. The Heruli appear to have been worshippers of Odin, and might have been responsible for the spread of such worship to Northern Europe.
By the time of Justinian, Procopius reports that many Heruli had become Arian Christians. In any case, Justinian appears to have pursued a policy of attempting to convert them to Chalcedonian Christianity.
Procopius writes that the Heruli practiced a form of senicide, having a non-relative kill the sick and elderly and burning the remains on a wooden pyre. Procopius also states that, following the death of their husbands, Herulian women were expected to commit suicide by hanging.
They are still, however, faithless toward them [the Romans], and since they are given to avarice, they are eager to do violence to their neighbours, feeling no shame at such conduct. And they mate in an unholy manner, especially men with asses, and they are the basest of all men and utterly abandoned rascals.
The translated "especially men with asses" is from the original Greek text (provided next to Dewing's translation) "ἂλλας τε καί ἀνδρῶν καί ὄνων" where ὄνων is genitive plural of ὄνος, meaning donkeys.
It appears that Procopius disliked the Heruli and wanted to present them in as negative light as possible. His description of bestiality among the Heruli might therefore be untrue.
Described the Heruli were famous for the quality of their infantry, who were recruited as mercenaries by all other peoples. They were known particularly for their speed, and were perhaps used for the stabbing cavalry. Procopius described the Heruli in battle against Persians, carrying no protective armor save a shield and thick jacket. This form of warfare has been compared to that of the berserkers of the Viking Age.
Herulian slaves are known to have accompanied them into combat. Slaves were forbidden from donning a shield until having proven themselves brave on the battlefield. This practice might be a relic of ancient Indo-European tradition. Steinacher has pointed out, that while this remark has reasonably been seen as evidence of an "initiation rite", initiation rites are so common that caution is required:
It is of course far from clear exactly what Procopius had in mind when writing about Herul 'slaves'. But he surely provided plenty of evidence that any gens was open to newcomers. As in any other human community, both in the past and in the present, such newcomers had to prove themselves worthy before receiving full membership in that community. This must have been even truer for a community geared towards warfare.
The tumuli of the Heruli on the Middle Danube in the early 6th century are very similar to contemporary tumuli built in southern Sweden. At this time, the Heruli appears to have had close trade relations with peoples living near the Baltic Sea.
Possible connection to Runic
In Getica, Jordanes writes that the Heruli claimed to be the tallest people of Scandza. Jordanes further writes that all the peoples of Scandza "surpassed the Germans in size and spirit". Sidonius Apollinaris wrote that the Heruli had blue-grey eyes.
The negative excursus of Procopius
Scholars remark that the historian Procopius had a notable fascination with the Herules, which colors his descriptions of them. As Steinacher remarks
"Procopius's Herul excursus [...] is full of stereotypes and negative attitudes towards this primitive people and its archaic conventions".
This means that caution is required when using his descriptions as evidence. In the words of Walter Goffart:
Though appreciative of their military qualities, he goes out of his way to blacken their character - "they are the basest of all men and utterly abandoned rascals," "no men in the world are less bound by convention or more unstable." His low opinion may result from the "special relationship" the Herules appear to have had with Justinian's eunuch general, Narses, who Procopius disliked.
Although Procopius praised the Herule named Pharas who brought about the surrender of the north African Vandal king Gelimer, he noted that despite being born a Herule, he did not drink excessively and was not unreliable.
Procopius was not mollified. The Herules were part of the panorama of an entire "West" that, owing to Justinian's neglect, had come into the possession of the barbarians by the late 540s. [...] The crowning irony, in the historian's view, was that, because some Herules served as Roman foederati, they both plundered Roman subjects and collected pay from the Roman emperor.
