the reason the germanic tribes of caesars and augustus times no longer existed as such during the late empire is because they merged into broader confederations, hun hegemony played a part but also the marcomannic war, dont remmeber by who but one myth highlights the sugambri as important to the frank ethnogenesis;
The allusion to
the Sicambri among the possible ancestors of the Franks is interesting.
Indeed, this people is mentioned in the Latin sources from 55 B.C in the Commentarii de Bello Gallico of Caesar.
Sicambri or Sicambers are also mentioned as peoples of either Celtic, Germanic or mixed cultures.
Like the Cimbri, and like their neighbours across the Rhine, the Eburones, many names of Sicambrian leaders end in typical Celtic suffixes like -rix (Baetorix, Deudorix, etc.). If the Sicambri were not Celtic speakers themselves, this could also indicate intense contacts with Celtic peoples across the Rhine in Gaul.
It should also be pointed out that when we speak of "Germanic peoples" or "Celts", we are in fact speaking of a confederation of peoples that may have
important differences, especially linguistic ones.
It would be hazardous to imagine, for example, that those whom the Greeks called the Galatians spoke a language close to those whom the Romans called the Gauls even if we call them Celts.
Gregoire of Tour refers to Sicambers in his chronicles:
https://en.wikipedia.org/wiki/Sicambri#Sicambri_as_poetic_name_for_Salian_Franks
...Salian Franks were called Sicambri. An example of this custom is remembered by the 6th-century historian Gregory of Tours (II, 31), who states that the Merovingian Frankish leader Clovis I, on the occasion of his baptism into the Catholic faith, was addressed as a Sicamber by Saint Remigius, the officiating bishop of Rheims. At the crucial moment of Clovis' baptism, Remigius declared, "Now you must bend down your head, you proud Sicamber. Honour what you have burnt. Burn what you have honoured." It is likely that this recalled a link between the Sicambri and the Salian Franks, who were Clovis' people.
More examples of Salians being called Sicamber can be found in the Panegyrici Latini, Life of King Sigismund, Life of King Dagobert and other old texts.
According to the German wikipedia the
Sicambri (Sugambri)
are the same tribe as the Cherusci and the Chatti.
They are identified as of 70 A.D in Latin sources as occupying territories which will be allotted to the Franks several centuries later:
These are the territories that would have been occupied by the Franks Saliens (in yellow) and Ripuaries( in brown) around 400-440 A.D.
It is not impossible that the Franks, especially the Ripuaries, were at least in part descendants of the Celts.
Therefore, not impossible that they have links (distant?) with the Galtatians, mentioned in my previous post ,who were known to the Persians since the 3rd century B.C.
It is only a bold theory

noworry

, but there are several references to links between Franks and Anatolia in ancient sources (allusion to "Trojans", Persian sources).
Perhaps

rolleyes

these references are not only effects of styles but clues to the history of little-known peoples.
