Early in the 20th century, the Georgian historian Ivane Javakhishvili introduced the term Sabediano, based on a standard Georgian geographic circumfix sa⟩ ⟨o, to refer to a polity—semi-independent of the kings of Georgia—which had come into being, by the 1470s, to bring together Mingrelia (Odishi proper), Abkhazia, and Guria under the aegis of the Dadiani princes with the style of Bediani. This view and the associated neologism were accepted by several Soviet-era scholars, including Zurab Anchabadze, who, however, dated the emergence of the principality of Sabediano back to the end of the 14th century, when the Mingrelian princes were reported by the Georgian sources to have had dispossessed their Abkhazian counterparts of their holdings up to and including Anacopia. The suggested boundaries of the principality, at its largest extent, were from the Chorokhi river to the Greater Caucasus crest and from the Tskhenistsqali to the Black Sea.
