Tran dynasty takes power in Vietnam

1225

After decades of Ly decline, the powerful Tran clan arranged the marriage of a child empress to their own candidate and assumed the throne of Dai Viet. The new dynasty would soon face, and remarkably repel, three separate Mongol invasions from the north. Their success owed much to a tradition of guerrilla warfare adapted to the rivers and jungles that steppe cavalry could not conquer.
