Bezhan was the second of Giorgi IV Dadiani by his wife, Princess Sevdia
Mikeladze, whom Giorgi divorced, in 1701, to marry Princess Tamar
Abashidze, daughter of the powerful prince
Giorgi-Malakia Abashidze, sometime
King of Imereti. In 1704, Giorgi made his eldest son,
Katsia, prince of Mingrelia and installed Bezhan as lord of
Lechkhumi, of which he had dispossessed his younger brother, Iese. Giorgi himself retired to the patrimonial fiefdom of
Salipartiano, but continued to wield significant influence on his sons until 1709, when Katsia and Bezhan—who never forgave Giorgi for divorcing their mother—forced Giorgi into flight to
Abkhazia. Giorgi returned as prince of Mingrelia after Katsia's death in 1710, but his renewed authority was challenged by Bezhan, who enjoyed support of King
George VII of Imereti. == Rise to power ==
