A while back, I asked about the fate of the Hellenistic states in the absence of Rome - ie, Rome met a sudden death (either at the hands of the Celts in in the early 4th century BC or the Carthaginians in the late 3rd century BC). Now, the next major question I'm asking here is wether the Migrations Period would occur in such a scenario in any recognizable form? I'm personally inclined to think "no" would be the answer, primarily because many of the push-pull factors which greatly catalyzed the migrations in OTL are absent, most importantly the absence of Germanic mercenaries in the service of Rome. It's also possible that some or many of the tribal alliances (most importantly, Franks, Saxons, etc.) that emerged in OTL in the 1st through 3rd centuries AD wouldn't come into existence because they're butterflied away.
Therefore, I'm asking, what do you think that could happen instead?
