Yes this post is about sea raiders, no this post isn't about vikings. The Germanic coastal tribes are in fact the earliest recorded sea raiders around the North Sea. Several accounts written by Romans, describe how Germanic warriors were a plague along the coasts of North Western europe, especially the coasts of Britannia and Gaul. The main target of these sea raiders? coastal Roman settlements.
Here is a small account described by Tacitus, the following event took place in 83AD in modern day Scotland:
"The same summer a Usipian cohort, which had been levied in Germania and transported into Britain, ventured on a great and memorable exploit. Having killed a centurion and some soldiers, who, to impart military discipline, had been incorporated with their ranks and were employed at once to instruct and command them, they embarked on board three swift galleys with pilots pressed into their service.
Under the direction of one of them ,for two of the three they suspected and consequently put to death, they sailed past the coast in the strangest way before any rumour about them was in circulation. After a while, dispersing in search of water and provisions, they encountered many of the Britons, who sought to defend their property. Often victorious though now and then beaten, they were at last reduced to such an extremity of want as to be compelled to eat, at first, the feeblest of their number, and then victims selected by lot.
Having sailed round Britain and lost their vessels from not knowing how to manage them, they were looked upon as pirates and were intercepted, first by the Suebi and then by the Frisii. Some who were sold as slaves in the way of trade, and were brought through the process of barter as far as our side of the Rhine, gained notoriety by the disclosure of this extraordinary adventure." - Tacitus, Agricola
Here it seems that a group of disgruntled Germanic auxiliary troops hijacked three galleys and went on a small tour of plunder before stranding on the coasts of the Frisii, modern day the Netherlands. But this is not the only account of piracy conducted by the Germanic people. One Germanic tribe in particular was quite infamous for raiding coastal settlements.
The Chauci tribe, who just like the Frisii lived on small terps right along the coast, mastered the concept of piracy. They were the neighbours of the Frisii, located to the east of them in modern day North-Western Germany. Just like the Frisii, it was for the Chauci absolutely essential that they knew how to sail/row, their landscape was one of water with virtually no trees or suitable ground for crops. Also unlike the Frisii, Batavi and Cananefates, their location was quite isolated, beyond the reach of the Romans.
The Chauci truly terrorised the coasts of Western Europe. Archeological research leads to the theory that raiding was pretty much essential for the development of the Chauci tribe and that they actually organized these raids quite carefully. The first wave of Chauci sea raids occured during the first century AD. Especially between 41-47AD, the Chauci plagued the coasts of Gallia Belgica, leading to much Roman frustration.
The second Chauci wave of raids is even more interesting. This time the Chauci raiders were led by a Cananefates man called Ganascus, the Cananefates were a Germanic tribe located in modern day Zuid-Holland, the Netherlands. Ganascus served as an auxiliary soldier in the Roman army but he deserted. This is the reason why the second wave was so succesful for the Chauci. Ganascus, as ex-Roman soldier, held a lot of knowledge about the structure of the Roman army, their defences, interesting targets and their strength.
The Chauci, under Ganascus, even managed to set a Roman fort on fire, Praetorium Agrippinae, which was located in modern day Valkenburg, the Netherlands. Their luck didn't last and eventually Ganascus was captured and executed.
Besides the Chauci, Usipeti and Cananefates, there was another tribe who took their ships to the sea and rivers to terrorize Roman forts/settlements along the borders of Germania, the Batavi. In 69AD the Batavi people revolted against the Romans, together with the support of neighbouring tribes like the Cananefates and the Frisii, the Batavi raided forts along the river Rhine and managed to capture an entire Roman fleet. The Batavi were even daring enough to engage in an open sea battle with the Romans near the mouth of the river Rhine.
After the Batavi revolt, a short time of relative peace returned to the rivers and coasts of Western Europe but the Chauci raids started to intensify again in 170AD. This time the Chauci raids were larger and more violent than ever. The Roman governor of Gallia Belgica was even forced to recruit more auxiliary troops in order to deal with these raiding Chauci pirates. The Chauci continued to raid the coasts for a few decades, their trail of destruction is still visible for archeologists until this very day.
Two villas in Armorica, modern day Bretagne, were destroyed. Several hidden coin treasures were found as well in Bretagne which shows that the Romans feared these Chauci raiders and tried to hide their valuables underneath the ground. Also modern day England wasn't spared. Several Roman settlements in modern day Essex were destroyed by the Chauci. The Romans desperately tried to defend themselves against these agressive sea raiders by building even more forts and by intensifying their patrols on the sea.
A small geographical change in the coastline of the North sea, from modern day Denmark to Flanders around 230AD, caused the sealevel to rise between 0,9-2,4 meters. This was of course a disaster for the coastal people who by then were part of the Saxon and/or Frankish confederation. Also the Romans were concerned about the rising waters and they began to pull back from the Rhine until around the location of the modern day city of Nijmegen. Together with the political struggles inside the Roman empire, this left the borders severely weakened and the Frankish saw their chance.
Yes even the Franks were known to have conducted sea raids and some of these Frankish sea raids didn't even occur in Western Europe. Around the year 260AD and the year 278AD, the Franks undertook two major sea raids along the coasts of modern day Spain and Morocco. They raided and terrorized settlements for about a decade before they were defeated by the Romans.
Ironically enough, a few captured Frankish pirates were send to the black sea to defeat raiding Goths. You can of course expect this to happen but the Franks stole a Roman galley and turned to piracy again. This was an incredibly dumb idea by the Roman emperor who gave this order, emperor Probus. Now the Franks were raiding settlements along the coasts of Greece, Libia, Sicilia and even Tunesia, until the Romans finally managed to beat them.
The Franks also raided the coasts of modern day England like the Saxons did. Archeological research shows that the Romans suddenly intensified the construction of forts between 250-280AD in Britannia. Eutropius, a Roman historian, described how the Saxons raided along the waters of Gallia Belgica, Armorica and Britannia. These raids eventually resulted in the invasion of Britannia by the Angles, Saxons, Jutes and Frisians.
The last Germanic folk, who sometimes made themselves guilty of piracy, were the Frisians. The Frisians flourished after the fall of the Roman empire. They were incredible traders and they were responsible for the creation of a huge trade netwerk and the growth of several trade settlements, which grew into modern day cities like: Dorestad, Medemblik, Ipswich, Norwich, Schleswig, Quentovic, Southampton and London.
Just like the earlier Chauci and Frisii, the Frisians lived, and still live, on terps. They were and still are surrounded by water so their ships were absolutely essential for their survival. They weren't agressive raiders like the Chauci but decided to focus more on trade instead. This rich trade network turned Frisia into a powerful kingdom and trade continued to grow even after their forceful conversion to Christianity. Unfortunately this all changed when the most famous Germanic people started to raid, the so called vikings.
