There were plenty of Gallo-Romans under Frankish rule in the early years. But the Franks themselves aren't on the list.
The distinction between "Frankish" and "Roman" was not a cultural one, but a civil-military one. Families that were eligible to provide military service were "Franks" under the law, and everybody else was "Roman". This did not match up with language even in the earliest days of the Merovingian state, when the military was effectively made up of the former Roman field army based on the Loire River - a field army that may very well have been comprised in large part by men who had family ties to the Frankish tribes to the northeast, but which was
also manned and officered by many men who had no such ties, who had been born in the Empire, and who spoke a variety of Latin. Such men and their descendants were designated "Franks" despite never having lived on the far side of the Rhine. Frankish identity fit well in part because the late Roman army in all parts of the Empire adopted elements of an identity that the Romans ascribed to the "barbarians" because that identity included many martial qualities that the military found it expedient to play up - so when elements of Roman identity, such as the allegiance to centralized Roman imperial authorities, became less and less of a draw due to the weakness of those authorities in the mid-to-late fifth century, many Roman soldiers elected to emphasize other layers of their identity, bringing "Frankish" to the fore.
Within a few decades of the creation of the Merovingian polity, the
cultural differentiation between those "legal" Franks that had antecedents external to the former Empire and those that did not continued to decrease - the adoption of Chalkedonian Christianity and the prominent use of Latin being the most obvious of these. To be sure, many others did not; for instance, the Frankish military aristocracy spent a great deal of time fighting each other (so much so that it can reasonably be called a social activity), something that did not tend to happen much under the Roman state. And it became politically expedient to continue to disassociate themselves from the Empire due to the activities and conquests of Ioustinianos in the sixth century. But these activities were not particularly uniquely
Frankish, either, and don't really constitute the sort of differentiation that lends itself to the classification of "civilization". I mean, I guess you could try, but it'd seem pretty forced.
Haha, you have a lot to learn about the world of history then.
Owen, this makes you sound like an abrasive, unhelpful dick. We're all aware that the whole project is flawed because of the problems inherent in defining what a "civilization" is. So forget that and just concentrate on sharing knowledge and helping each other
learn about this stuff.
