This paper provided brief comparative chronology of Mongolia, Korea and Vietnam. In the first part it focused on their mutual relations with shared Inner Asian neighbor in North China. Especially this larger supra-regional perspective enables multi-layer analysis of repeated re-unifications and understudied migrations in multi-ethnic Inner Asia. Second part of this paper was focused on varying, but also shared ways of religious legitimation of power. This part was documenting ethnopolitical and transnational construction of Inner Asian sacred statecraft. Third interconnecting section offered cases of main imperial symbols used by many contact ethnic groups. And it was also mentioning understudied ways of the spread of religions and religious thinking into neighboring countries of Inner Asia. Concluding synthesis was focused on environmental factors as active drivers in the constitution of changing heterogenous homogeneity in Inner Asia.
