The name "Bohemia" derives from the name of the Boii, a Celtic tribe who inhabited that area towards the later La Tène period. The toponym Boiohaemum, first attested by Tacitus,[2] is commonly taken to mean "home of the Boii" (from the Germanic root *haima- meaning "world, home"). The word "Bohemian" has never been widely used by the local Czech (Slavic) population. In Czech, the region since the early Middle Ages has been called Čechy ("Czechia") but also, especially during the period of restoration/emancipation of the Czech language and nation, as Čechie. Another term, stressing the importance of the state/nation, is Království české ("Czech Kingdom") in Czech, or Böhmen (Königreich) in German. Its mainly Czech-speaking inhabitants were called Čechové (in modern Czech Češi).
