According to the mainstream Georgian scholarship, Bagrat was a son of Prince Teimuraz and a grandson of King
Bagrat III of Imereti. Professor
Cyril Toumanoff considered Bagrat to have been a son of another Teimuraz, son of
Prince Vakhtang of Imereti. Enthroned through the support of
George II Gurieli,
Prince of Guria, Bagrat briefly ruled during the civil war in Imereti until being deposed by
Simon I of Kartli in 1590. ==References==
