The Uar (also Var or War) are the largest of three ethnic components constituting the confederation known to the west as the Hephthalites and to the Chinese as Yanda and the dominant ethnicity of Khwarezm.
Peoples with similar names have been present along the Silk Road for centuries, and several Central European family names actually derive from the names of these tribes.Theophylaktos Simokattes uses the name Uar, sometimes written as War or Var.
According to the Chinese classic Liang chih-kung-t'u the name Huá was an endonym used by the Hephthalites themselves while Yanda was an exonym derived from their ruling dynasty and applied to them by outsiders.
