I have a suggestion.
I think it will be great if in games we can play with other civilization who are not so famous.
Everyone can suggest new civilization.
My suggestion is the Bulgars.
Let me tell you fast for them...
The Bulgars were people from the Eurasian Steppe.
They are known as great horseman warriors who has no fear.
For the first time they were mentioned in The Chronography of 354 in the text „Ziezi ex quo vulgares“(Ziezi, of whom are the Bulgars) (Ziezi was a son of Shem and a grandson of Noah.). Many people associated them with the Huns, or Scythians.
Beginning of the Bulgarian state according the Nominalia of the Bulgarian khans is in second century, the rulers Avitohol and Irnik from the Nominalia are related to Attila and his 3rd son Ernakh.
The first country with the name Bulgaria, was created by khan Kubrat in 632. He united the bulgar tribes in the Pontic-Caspian steppe. This country was known as Great Bulgaria.
After the death of Kubrat, Great Bulgaria was conquered by the Khazars
But his five sons separated and left with their tribes to seek new land for the bulgars...
The first son - BatBayan stayed at motherland
The second son - Kotrag has settled with his tribes between the rivers Volga and Kama and there in 660 he create Volga Bulgaria
The third son - Asparukh has settled with the royal tribe of the bulgars between Balkan Mountains and Danube river in 670.
After the Battle of Ongal in 680 betwen Asparukh bulgrars and Byzantine Empire
The Byzantines were defeated and forced to sign a peace treaty in 681 with which are given the beginning of the First Bulgarian Empire on Danube
The other two sons of Kubrat - Kuber and Alcek settled in Pannonia, but later Alcek went in Central Italy and Kuber in Vardar Macedonia.
Danube Bulgaria and Volga Bulgaria become one of the most powerful countries in medieval Europe.at the Danube delta.
One of the most spectacular battles in the the European Middle Ages are the work of the Bulgars.

by Gen. Maslama, relieving the Arab siege of Constantinople.
