The Salian Franks, or Salians, sometimes referred to by the Latin word or , were a Frankish people who lived in what is now the Netherlands in the 4th century. They are only mentioned under this name in historical records relating to one period when they came into conflict with Roman forces led by Julian the Apostate around 358 AD, when he was ruling Gaul as Caesar under his cousin the emperor Constantius II. In modern times scholars have also traditionally used the term "Salians" to refer to the much later Franks who became the rulers of much of present day northern France in the 5th century - at first under the leadership of Chlodio, and later under the leadership of the Merovingian dynasty — seeing them as the descendants of the original Salians.
Roman sources describing the events of 358 AD indicate that the Salians were a Frankish people who had entered the empire from across the Rhine some time earlier, and settled with Roman consent in Batavia, which is a large island in the Rhine delta, that lay on the northern boundary of the Roman Empire. They had subsequently been settling in the relatively unpopulated and infertile area of Texandria, south of the delta, which was still considered to be under direct Roman control. They were also one of the tribes of this region who were being paid off by the Roman government to allow the safe passage of grain shipments up the Rhine, along with another people, the Chamavi. Julian, seeking to end the payments, entered the region with military force. After defeating both peoples and taking hostages he proclaimed new agreements with them, authorizing the Salians to keep any lands they had settled without fighting, but forcing many of the Chamavi to return to their homeland. He also obliged both peoples to contribute soldiers to the Roman military. Consistent with this, Julian is known to have created several military units named after the Salians.
Until the 1950s it was also generally accepted that the Salians subsequently expanded their territories to the south, and became one of two large divisions among the Franks in the 5th century — the other being the Ribuarian Franks, living to their east. This proposed division is not described in any contemporary records, but rather based on the names of two distinct legal codes used by the Franks after they were united under Merovingian rule. The older one, the so-called Salic Law () was valid in what is now northern France, and its name might be related to the name of the earlier Salians, although this is no longer considered certain. The later one, the , in contrast, is associated with the region near Cologne in what is now Germany. In the 21st century, scholars no longer generally accept that the term "Salic" in Salic law referred to any specific tribe by the 5th century, and some historians argue that it never did. It is also no longer widely accepted that the two Frankish legal codes imply two distinct Frankish peoples.
Name Many etymologies for the word have been proposed, but the origins of the name remain uncertain. One of the challenges is that the name is so short, which means that there are many similar sounding words. When considering the possible etymologies, scholars are also confronted with questions about whether the word is related to much later terms including Frankish Salic law, the Frankish legal concept of (the demesne lands of the lord of the manor), the regional name Salland north of the river delta in the Netherlands, or the name of the river IJssel which flows through Salland.
The proposal of Norbert Wagner and is that the name has a Germanic etymology, related to such modern words as German , meaning a companion or journeyman. It was argued by Wagner that these terms are furthermore related to , meeting house or hall, because companions share accommodation. For scholars who accept such proposals the Salians in 358 AD may simply have been calling themselves a group of confederates or friends, and the much later Salic law may have had a meaning equivalent to "civil law". Less widely accepted, Springer has even argued that the term in 358 AD was misunderstood by Roman authors, and was actually a Germanic term for the Franks in general.
Other possible etymologies include these: Based on the report of Zosimus that the Salians moved into the Roman Empire from somewhere north of the Rhine, older scholarship proposed that the name may have derived from the name of the IJssel river, formerly called Hisla or Isola in the oldest medieval documents. In contrast, another old proposal was that the Salians became a people only once they settled together on the island of Batavia, and that their name is therefore based upon an otherwise unknown Germanic word for "island", meaning they were "island dwellers". A connection has been proposed to words for "salt", which are similar in many languages. An argument against this is that the Salians, and the regions where they might have lived, including Salland and the IJssel, were not near saltwater during the Roman era. It has also been proposed that the name is related to an Indo-European word for jumping or leaping, such as the Latin verb , from which is derived the similar name of an order of leaping priests of Mars in Rome, called the Salii. There is however no generally agreed explanation about why this would be their name.
The campaign of Julian in 358 AD Only Zosimus, who wrote around 500 AD, gives information about the Salians before 357 AD. He describes them as a people detached or separated from the Franks (), who had been expelled from their own country by the Saxons and settled at some time prior to 357 AD on the large island of Batavia, between two branches of the Rhine. Although Batavia was within the boundaries once governed by the Romans, the Salians were governing it by 357 AD. He describes the Saxons who forced them there as the strongest of all the barbarians dwelling near that Rhine delta region.Zosimus, New History 3.6. Greek, English, or here. A more contemporary source, Ammianus Marcellinus, also associated the Salians with the Franks, calling them Franks "whom custom calls the Salii".Ammianus, Res Gestae, 17, Latin, English, or Book XVII-8 here.
The Romans had inconsistent and incomplete control of the Rhine delta since the crisis of the third century. The population and agricultural activity had decreased dramatically, and the Romans had given it up as an area for normal taxation and governance. Some modern scholars believe the Salians attacked by Julian to be descendants of the Frankish who Constantius Chlorus allowed to remain in Batavia around 293-294 AD, when the Romans reasserted themselves there after the revolt of Carausius. They were probably also descended from the Franks who were later allowed to settle in Texandria by the brother of Constantius II, his co-emperor Constans, already in 342 AD, after fighting there in 341 AD. Julian also associated the usurper Magnentius, who had killed Constans and ruled the region in 350-353 AD, with the Franks and Saxons of this region. citing Eumenius, Panegyric VIII(5) written about 298 AD. At the Battle of Mursa Major in 351 AD in present day Croatia many Roman soldiers with Frankish and Saxon backgrounds died fighting in this Roman civil war. Like Magnentius himself one of his main commanders Silvanus, who defected to Constantius, had Frankish ancestry. He was given the task of rebuilding defences in Gaul, but killed as a rebel in 355 AD. In the same year Julian was given the rank of Caesar, and assigned to rule Gaul under his cousin Constantius, and rebuild the Rhine defences against the Franks and Saxons who Magnentius had apparently coordinated with.
Julian's campaign against the Salians was at least partly triggered by a Roman concern with bringing grain shipments from Britain safely up the Rhine, without being impeded by the Salians and other Rhine delta peoples. Libanius (Oration 18.83) an orator who corresponded with Julian and wrote his funeral oration, emphasizes the problems caused by barbarians on the Rhine blocking such grain shipments. Both Libanius and Zosimus (3.5) reported that Julian, wanting to supply inland areas where cultivation had been ruined by other conflicts, built a fleet on the Rhine and began shipping grain up the river to Roman cities. In his letter to the Athenians Julian however complained of the disgrace that despite quick construction of a large fleet, the praetorian prefect Florentius sent to Gaul by Constantius II in 357, "promised to pay the barbarians a fee of two thousand pounds weight of silver in return for a passage". Julian decided that this payment to the barbarians should not be made, and instead he marched against these barbarian tribes - specifically the Salians and Chamavi. His account of the campaign itself is compressed: "I received the submission of part of the Salian tribe, and drove out the Chamavi and took many cattle and women and children. And I so terrified them all, and made them tremble at my approach that I immediately received hostages from them and secured a safe passage for my food supplies".Julian, Letter to the Athenians, https://www.tertullian.org/fathers/julian_apostate_letter_to_the%20athenians.htm The conflict between Julian and Florentius itself appears to be part of a set of related disputes for fiscal control of northern Gaul, and Julian may have been disrupting a prior state of affairs which entailed integration of the Chamavi and the Salians into imperial systems of military taxation and supply.
Another turn of events which triggered this campaign was the entry of the Chamavi into the Roman region south of the Rhine. According to Zosimus the barbarians of the delta region were losing all hope because of Julian's policies on the Rhine, and they were expecting the complete destruction of everyone who still lived there. Apparently in reaction to this, the Saxons sent a faction of a Saxon people called the "Quadi" (by which he apparently meant the Chamavi), into the land held by the Romans.The Quadi are a very well-known enemy of the Romans who lived far away, in the area of modern Slovakia. They are in fact mentioned by Zosimus and Ammianus in other parts of their works. Scholars therefore believe this particular passage of Zosimus is faulty, and that he means the Chamavi, a people from north of the delta who were named as the second people involved during these events by more contemporary sources such as Ammianus, Eunapius and Julian himself. See for example and . has suggested that Zosimus' confusion may lie in references in these contemporary sources to Constantius' campaigns against the Quadi in adjacent sections of their narrative to those where Julian's campaigns against the Salians and Chamavi are discussed, e.g. Ammianus, Res Gestae 17.2.1 and Julian, Letter to the Athenians 279 According to Zosimus, these "Quadi" (Chamavi) used boats on the Rhine to get around Frankish tribes who effectively protected the Roman frontier, and into the Roman river delta, where they expelled the Salians from Batavia and established a base for themselves. Ammianus simply says that the Salians dared to start building homes within Roman territory in Texandria, and that the Chamavi attempted to do something similar. Zosimus, in contrast, describes the Salians as friends of Rome who were forced by the Chamavi into these Roman territories. He claims that Julian gave instructions to attack the "Quadi" (Chamavi) speedily, but not to kill Salians, or to prevent them from entering Roman territory, because they had not come as enemies, but had been forced there. He added: "As soon as the Salii heard of the kindness of Julian, some of them went with their king into the Roman territory, and others fled to the extremity of their country, but all humbly committed their lives and fortunes to Caesar's gracious protection".
