Калмыцкое ханство
During the era of Ayuka Khan, the Kalmyk Khanate reached its peak of military and political power. The Khanate experienced economic prosperity from free trade with Russian border towns, China, Tibet and with their Muslim neighbors. During this era, Ayuka Khan also kept close contacts with his Oirat kinsmen in Dzungaria, as well as the Dalai Lama in Tibet.
