well, Angela, I didn't make the in-depth study as you urged me to, but I stumbled on this, see after 6:15 :
so, before Caracalla, Roman citizinship was for an elite, after it was for all free men in the Empire, is that correct?
and some historians don't think it was a smart move, they say it made Rome dependand on those smelly, illiterate barbaric mercenaries you despise so much
what is your take on that?
First of all, I don't "despise" the Germanics who tried to enter the empire and ultimately were the coup de grace which brought it down. Just, by the way, as I don't despise the often illiterate, not westernized people trying to enter Europe today. I don't want to be insulting, but please don't project your feelings on to me as to the latter.
If anything I feel sorry for both groups, and wish they weren't in that situation. However, the issue was whether either polity could accept unlimited numbers of such people into their borders. I think the answer is no.
Second of all it would be a bit of self hatred on my part to despise those Germanics. While it may be a minority part of my ancestry, they did have some influence on my genomics.
I'm trying to be as objective as possible about all of it.
Now, do I think it was a "smart" move for Rome to accept the Germanics as mercenaries, in their own mercenary units, answering to their own commanders, and relying on them so heavily for matters of defense? Absolutely not, as I emphasized already in my post upthread. I think it should be an absolute rule, if you will, NEVER to become dependant on mercenaries no matter the country, the ethnicity of the mercenaries, or the era. Think of the Mamalukes of Egypt as one example which pops to mind. The only situation which comes to mind which was pretty successful were the Janissaries of the Ottoman Empire, but the Ottomans took the precaution of removing the boys from their families and home countries at a very young age, raising them strictly in dormitories, indoctrinating them in Islam and loyalty to Ottoman rule, and not granting them the right to marry. Even then there was eventually trouble.
As to the nature of Roman citizenship in the Empire, you really shouldn't rely on youtube videos.
It's a complicated issue because its nature depended on the precise time and place being discussed. There were areas which had what amounts to "universal" male citizenship long before Caracalla. I would remind you that universal male citizenship in the modern world wasn't granted in a lot of places until the 20th century. Your standards for Rome are almost absurdly high.
However, in many, many areas and situations, it was indeed not limited to the "elite" in the sense you mean. I'll just provide a few examples:
Slaves of Roman citizens who were legally manumitted were automatically citizens. Does that sound like giving citizenship only to the elite to you?
The treatment of conquered territories depended on who was in power in Rome and the political situation at the time. In the early years on the Italian peninsula some areas were incorporated directed into Rome, and all inhabitants became Roman citizens. In others they were considered allies, and the acquisition of Roman citizenship depended on services to Rome. Eventually, local magistrates could confer that citizenship, for example to a tax collector or necessary merchant of tradesman. Even well before the time of Augustus, all of Italy was granted citizenship.
Cisalpine Gaul received the "Latin right" in 89 BC, and in 49 BC Giulio Cesare granted citizenship to all inhabitants.
Then there were the hit and miss situations. When the taboo against settling veterans outside Italy was lifted, and colonies were established all over the Roman world, citizenship was often granted to locals who were associated with or came to live in those colonies.
During the Empire, the practice also began of granting citizenship to tribal groups which chose to ally with Rome, and service as auxiliary troops in the Roman army also resulted in a grant of Roman citizenship. Claudius institutionalized it, and thereafter anyone serving in the Roman military received citizenship.
I could go on and on, but I think you get the drift.
No, citizenship was not something granted only to "elites".
