The Guduscani or Goduscani (Croatian: Guduščani, Gačani) were a tribe whose location and origin on the territory of early medieval Croatia remains a matter of dispute.
[7] The old consideration that the Guduscani originated from the territory of Moesia (present-day Serbia) and that together with the Timočani became allies of the Franks is disputable due to lack of evidence and arguments.
[12] In 818 they were part of an envoy of Borna sent with the other South Slavic tribes (nationes) of Timočani and Praedenecenti (possibly an off-shot of Abodrites) to the court of Louis the Pious in Herstal.
[15] Depending on the interpretation of the Byzantine and Frankish sources, some historians consider them to be a tribe separate from the Croats and that the emergence of the Croatian political identity and power is not related to the region of Lika yet of Northern Dalmatia.
[17] The view that the Guduscani were Gothic remnants is not widely accepted, as the state of the Goths was in Italy and it ceased to exist in the mid-6th century, while their presence in the former Roman province of Dalmatia and Liburnia was not dominant, however, there were Valagoths as well in the region.
