When was the Mongol power formed?

In Mongolia itself, the date of the formation of the state is considered to be 1206, by which time Genghis Khan united all the Mongol tribes and under his control was a territory that exceeded the area of modern Mongolia, for example, Tuva and Buryatia were also part of his empire.

Over the next 20 years of his life, Genghis Khan and his commanders were able to conquer the northern part of China (they took Beijing, captured the Tangut and Khitan states), ravaged Central Asia (Khorezm), invaded Transcaucasia and in 1223 even reached the Azov region, where they met with the Russians and Polovtsians.
