A. Mayorov distinguishes between the terms and concepts of "White Croatia" and "Great Croatia". He agrees that White Croatia and those Croats identified as "White" appeared to have some historical presence in the Upper Elbe and Upper Vistula regions since the late 4-5th or later century, but that Great Croatia, the pre-motherland for the Croats, was located in Eastern Prykarpattia and Tisza river basin in Zakarpattia. Mayorov suggests that the author of the "DAI" made an attempt to reconcile the contradictions among various conflicting sources.
