I've been interested in Colchis since I first read Jason and The Argonauts. As a borderland between Slav and Turkic superpowers over the last couple of centuries my attenion has been drawn to the region. The Byzantine connection can hardly be ignored, and it's more than likely that the "kingship" of some Georigian clan was an Imperial grant.
Fine. Great. Now tell me why you make such a glaring ******** statement like
"There's no historic Georgian Kingdom", a statement whch is either dishonest or horribly ignorant, and then when you get called out on it, all you can do is act like a prat
and attack me and sentence structure? Was that
really the best you could think of on the spot? Bit of an awfully twattish reply, that one of yours.
It's a ******** claim of yours yet again about the Imperial grant; sheesh, which Imperial power are you talking about? I wouldn't put it past you to be
that ignorant. The Byzantines? Pretty defunct by the 11th century; the Russians still paying tribute to the Mongols; the Georgian kingdom existed because it created itself by force. You going to try pretending that King David IV or Queen Tamar were only royal rulers by Byzantine decree (I assume; I hope to god you really don't mean a Czar or something, though given your posts here, you
might 
). Sheeesh, what are you relying on? Russian disinfo hand-outs done on the back of old cig packets?
If you prefer, I can do monosyllables for you; as it is, normally you are much more rational in your posts, so I want to know the reasons for why your very evident bias. Answer the question.
Logistics. Look it up. Then look up 8thCE Arab supply-trains. See the problem?
You are only displaying
massive (and rather astonishing) ignorance all over again. The Arabs in their expansionist period displayed amazing logistics ability; how do you think they conquered so much? Magic?
Hello? Hellloooo? Planet Earth calling you; how do you think the Arabs conquered Iran, Egypt, etc. etc.? Helloooo? Anyone at home in there?
Have you read
any proper history at
all?
Then look up "morale" and "motivation".
Coming from you, when you appear to be woefully ignorant of Arab military history and early success, I find that rather funny.
A quick question when did you first hear of the Caucasus? Follow-up question : why do you think you know anything about it?
Well, certainly, I obviously know rather more than you do on this and related subjects.

Although that's setting the bar rather low.
How about you first explain your very evident bias
first, seeing I've asked now three times, and
then I answer your questions?

That seems fair to me.
