The Later Lê dynasty early period from 1428–1527 is a distinction current in writing on the history of Vietnam to distinguish the 100-year-long early period of the Later Lê, when the emperor-kings both ruled and held real power, from the 256-year-long Later Lê dynasty warlord period when, following a six-year civil war, the emperor-kings were restored as figureheads, but power was held by a succession of warlords.
