Tay Son

The name of Tây Sơn (西山) is used in many ways referring back to the period of peasant rebellions and decentralized dynasties established between the eras of the Later Lê and Nguyễn dynasties in the history of Vietnam. Sometimes the name Tây Sơn is used to refer to the leaders of this revolt (the Tây Sơn brothers), sometimes it is used as the name of the war (the Tây Sơn Uprising) or it could also refer to the brothers' form of new governmental rule (the Tây Sơn Dynasty or Nguyễn Tây Sơn Dynasty).[1]
