I planned to open a topic for that and then I saw your thread

I'll expand it a bit ^^
At the edge of South-Eastern Europe lies Georgia, country dating its statehood since legendary kingdom of Colchis. Georgians have their unique language, unique alphabet and one of the oldest autocephalous orthodox churches. Christian country since 325 AD, Georgia was developing with cooperation with other Christian countries (mainly Fellow orthodox Byzantine empire) and was one of the bastions of Christianity at the borders of Europe.
Leader: David IV "the builder"
David IV ascended on throne at 1189 and was one of the most successful kings of Georgia. By the time, Georgia was weakened by seljuk invasions and civil wars. He managed to defeat rebellious feudals and stabilize the country. He slowly drove out seljuks and at 1121 at battle of Didgori, Georgians managed to defeat huge muslim coalition. The victory at Didgori signaled the emergence of Georgia as a great military power and shifted the regional balance in favor of Georgian cultural and political supremacy

. Victory was important not only for Georgia, but for Christians in General, mainly for Crusaders, who were considered by David IV as his natural Allies and vice versa. David IV had rebuild many churches and forts, destroyed during the war, founded academies of Gelati and Ikalto and restored Kingdom from ruins, hence nickname "the builder". Member of the dynasty, that considered itself to be descendant of biblical king David, David IV wrote "Hymns of Repentance", a sequence of eight free-verse psalms, and by that linking himself with his legendary ancestor.
national ideas:
1)Kmadnapitsoba (Vassalage): main expansion strategy of medieval Georgia was creating small bordering vassal states and slowly incorporating them. before Mongol invasions, Georgia controlled many vassal states and dependencies, from small north caucasian counties, to empire of trebizond.
bonus: relations with city states wont decrease if they are allied.
or extra diplomatic options for annexing city states (like with maria teresa at civ V)
2) Surrounded by larger rivals, Georgians always fought wars against more numerous enemies and won most battles against them.
bonus: while defending, damaged units fight like healed ones (like japanese in CIV V perhaps?)
unique unit:
either
1)Monaspa cavalry (replacing knights): elite cavalry units, serving king (thats what it literally means, "servant army")
or
2)Metsikhovneebi (fort Guard) armed with firearms and replacing arquebusiers if we want to to add men with guns. Of course fire arms were adopted 3 centuries after King David, but these units were created by him as distinct military entity (first armed with bows and swords, then adopted firearms). tbh, reason I'm suggesting them is because our national uniform "chokha" was spread after usage of firearms and adding them in game would be lovely
unique building:
svan tower: alongside of its defensive bonus (like fort), svan towers could produce additional culture and gold (they were actually used for safeguarding treasure). must be built on hills.
colors:
red and white (current flag colors)
or
dark red and black (colors of flag of queen tamar)
symbols:
Bolnuri cross (Georgian version of cross pattee:
or
borjgali (ancient Georgian symbol of sun):
