Franks (Latin: Franci): tribal federation on the north and east bank of the Lower Rhine, which created a late antique kingdom in France.


Reconstruction of a Germanic farm

The Germans who harassed the Roman Empire from the third century CE did not belong to the tribes that had been familiar to the Romans for many centuries. More powerful and aggressive enemies appeared on the other side of the Rhine: the Alamanni in the south of what is now called Germany, the Saxons along the German shore of the North Sea, and the Franks in Westphalia and the north of the Netherlands. As the name Alamanni (“all men”) suggests, these were groups of warlords from old tribes who had banded together.

The Franks, which means either “war hungry” or “the free ones”, were a federation of Chamavi, Amsivarii, Chattuarii, Bructerii, and Chatti. The Tubantes and Salians may have been part of the Frankish federation as well. Another tribe may have been the Frisians, who lived in the Dutch coastal area, which was abandoned at precisely this moment. The inhabitants may have migrated to the interior, may have merged with the original population, and may thus have been at the beginning of a new ethnic unit. From an archaeological point of view, villages like Wijster (Netherlands) offer something quite new.

Roman portrait of a German leader

If the sources are reliable – something that we will never know for certain – the emerging tribe had a warlike character. There were several warlords, who had followers who would stand by him through thick and thin. In return, they were provided for and, very importantly, were given many presents. Gold, in particular, was a valued gift, and it was considered a great act of valor to seize this precious metal as booty during raids into enemy territory. The thirst for gold accounts significantly for German incursions into Germania Inferior.

Successes like these are easy to explain: the Germans had learned their military skills from the Romans by doing service in special auxiliary units for foreigners. The squadrons of Tubantes and Frisians are examples of these units. After their demobilization, the returning veterans obtained leading positions in their tribes, on account of their extensive military experience, and, of course, the wealth they had accumulated. In this way, differences in status and wealth began to arise in the once so egalitarian tribal societies.

It now became customary for wealthy leaders to arrange marriages for their children with other equally rich leading families, and, in this way, family ties were formed between the different members of what was gradually becoming a tribal elite. Intermarriage of the Germanic elites was crucial. Organizing trade with the Roman army along the Rhine must have been another factor that stimulated cooperation.

A late antique francisca

The new elite was proud of its Germanic origins. They had a "national weapon", which came to be associated with the Franks, even though other people used it as well: the throwing axe or francisca. Here is a very stereotypical description from c.460 CE:

These monsters have red hair which falls over the forehead from their high crown, while the back of their head is bald and shines nakedly. Their watery eyes are white and have a blue shine. Because their faces are almost completely clean-shaven, they run their comb through their modest moustaches instead of through their beards. They wear tight clothes that are stretched high across their big male parts, so that their sturdy knees are exposed. A wide belt girds their slender loins. It is a sport for them to throw their fast axes through the air from a great distance and to know in advance where they will land; to turn their shields so fast and to leap so quickly ahead that they will get to their enemies before the spear they have hurled. In childhood, their warlike behaviour is already that of an adult.note

Stereotypical, certainly, and probably even a joke, because it is not very likely that the Franks tried to reach their enemies before the impact of their own missiles. However, the author, Sidonius Apollinaris, knows correctly mentions throwing axes as a weapon employed by the Franks. Franciscas have indeed been found in many tombs in Belgium, France, and Germany.

Enemies, mercenaries, pirates

A treasure from Reims, dating to the year 260 CE, probably buried when a band of Frankish warriors was approaching.

The first big Frankish invasion took part in the 250s. Benefiting from the war between Rome and the Sasanian Persians, they attacked. Archaeology shows the consequences: the forts on the Lower Rhine were temporarily abandoned; the population of Krefeld did not have time to cremate their dead and instead threw the corpses into an underground temple; Trier was sacked. One band of Franks even crossed the Pyrenees and reached Tarraco in Spain.note

Postumus' Frankish triumph

The emperor Gallienus managed to restore order but had to leave this theater of operations when he learned that his father Valerian had been taken captive by the Persians (260 CE). He left the war to Postumus, who decisively defeated the Franks, and declared himself independent. The Gallic Empire, as it was called, managed to contain the Frankish threat. One instrument was to hire Frankish warlords and employ them in the Roman army.note

After the emperor Aurelian (r.270-275) had subdued the Gallic Empire, he took the new Rhine army with him to fight the Palmyrene Empire in the east, and again, Frankish warlords invaded Gaul. The Alamanni did the same. The emperor Probus (r.276-282) however, expelled them and restored the Roman frontier along the Middle Rhine.note He may have received the honorific title Francicus.note One group of captives managed to do the nearly impossible, as an anonymous orator recalled several years later, mentioning

the incredible audacity and undeserved good fortune of a few Frankish captives in the time of the deified Probus, who, seizing some ships, plundered their way from the Black Sea right to Greece and Asia and, driven not without causing damage from very many parts of the Libyan shore, finally took Syracuse itself, once renowned for its naval victories, and, after traveling on an immense journey, entered the Ocean.note

Two groups of Franks

When we take a closer look at our sources, it seems as if there were two groups of Franks: an eastern group from the area opposite Cologne that was often hostile, and a more peaceful northern group in the eastern part of what is now called Netherlands. Both groups could be sedentary and mobile, but while the first group's mobility had a lot to do with warfare, the second group's mobility appears to have consisted or bringing cattle from winter to summer pastures. The fact that the area directly north of the Rhine benefited from Roman demand,note seems to confirm that the northern group was integrated into the Roman economy, which points at generally peaceful relations between the Roman and Frankish neighbors in the Lower Rhine area.

It is tempting to connect these two groups to a later distinction between the Salian Franks, who in the mid-fourth century arrived from the north and settled in what is now called Belgium, and the Ripuarian Franks, who would settle in what is now called North Rhine-Westphalia, the Palatinate, Saarland, and the northeastern part of France. In the Merovingian age, there was indeed a distinction between Salian and Ripuarian law, but there is no evidence that the Ripuarian Franks existed as a unit before then, so we should probably resist the temptation to identify these two Merovingian groups with the two third-century groups.

The Panegyrici Latini

Constantius I Chlorus

The collection of speeches known as the Panegyrici Latini offers more information about the events between, say, 285 and 315 CE. We learn that in c.288, the emperor Maximian (r.285-305) spared a Frankish leader named Gennobaudes.note Imperial recognition may have helped this man become a real king with a real kingdom. We read about Franks who served the rebels Carausius and Allectus, who ruled in Britain from 286 until 296. The island was subject to Rome again by Constantius I Chlorus (r.293-305).note

Grave gifts from a German mercenary in the Roman army: a Germanic fibula, some Germanic pottery, and some Roman terra sigilata.

We also learn that Constantius defeated Franks on the continentnote and resettled them as farmers on empty land.note When he was again in Britain (where he would die in 306), the Franks became restless again, but Constantius’ son Constantine the Great captured and executed two of their leaders, Ascaricus and Merogaisus in the amphitheater of Trier,note and proceeded to attack the Bructeri on the right bank of the Rhinenote and build a bridge across the river near Cologne.note The bridgehead has been excavated at Deutz.

It seems that Rome, which had acted defensively in the third century, had started a more offensive strategy: after Constantius had recovered what had been lost, Constantius started to attack the Germans in their homeland. Hiring Franks as mercenaries, as Postumus and Carausius had done, and creating vassal kings like Gennobaudes, as Maximian had done, must have been supplementary instruments.

It is also clear that the Frankish leaders attacked when Roman troops were employed somewhere else. (Nothing had changed since the Batavian Revolt.) When Constantine was occupied with Maximian in the south, in 310, there was a minor Frankish crisis,note which was solved when Constantine was already on his way back to the north (and saw the celestial sign that made him famousnote).

In 312, when Constantine was in Italy, fighting against Maximian’s son Maxentius (culminating in the battle of the Milvian Bridge), another group of Franks attacked, but Constantine restored order. After this, the Rhine frontier appears to have stabilized, although we learn about a campaign conducted by Constantine’s son Crispus in c.319.note
