The Dulebes, Dulebs, Dudlebi or Dulibyh () were one of the tribal unions of Early Slavs between the 6th and the 10th centuries. According to medieval sources they lived in Western Volhynia, as well as southern parts of the Duchy of Bohemia and the Middle Danube between Lake Balaton and the Mur River (a tributary of the Drava) in the Principality of Hungary, probably implying migrations from a single region.
== Etymology == The etymological origin of their ethnonym is uncertain. Jan Długosz argued it derives from the name of their supposed progenitor, Duleba. Others, such as Oleg Trubachyov consider that the ethnonym existed before the Early Middle Ages because it derives from West Germanic languages; *dudlebi from *daud-laiba- in the meaning of "inheritance of the deceased", which would fit "with the early historical process of development of the lands by the Slavs abandoned at one time by the Germanic tribes". Initially, the Proto-Slavic tribe possibly was part of Przeworsk culture near Old Western Germanic area, but later belonged to the Prague-Korchak culture. It would be "only Slavic ethnonym with a Germanic etymology".
