Internative marriage system, built by the Tran dynasty (1225–1400), its main objectives, forms and collapse

Since the emergence of the Far Eastern empires, the fundamental principle of the transfer of power in the dynasties that ruled here strictly along the male line and strictly downward was regularly attacked, often successfully, by the female family lines of the ruling families, in particular, by mothers, wives, fathers-in-law and sons-in-law of the emperor, which constantly aroused deep concern among the representatives of the main lines. In the XIII-XIV centuries, the Tran dynasty, which ruled Dai Viet (Vietnam), tried to create and put into practice such a system of transferring the throne within the framework of its house, which would exclude even the theoretical possibility of such encroachments. This article is devoted to a description of the specific measures that were taken in connection with this, as well as the events that led to the destruction of this system and ultimately to the fall of the Tran dynasty and the transfer of power in the country to the Ho dynasty, and formally it was through the female line.
