After the death of Bezhan in 1728, Levan Abashidze's influence grew, and he married off his daughter Tamar to Alexander V as the king's second wife in 1732.
Prince Levan fought on the side of Alexander against the powerful party of nobles led by Bezhan's son Otia Dadiani in a debilitating civil war, but he later fell afoul of his royal son-in-law, and the two clashed with their forces in 1745.
[1] After Alexander V's death in 1751, Levan Abashidze opposed the accession of the royal heir, his own grandson Solomon I, who was briefly deposed in a coup which was supported even by the king's mother in 1752.
[2] Once Solomon regained the throne, he forced his mother and grandfather into exile and confiscated the Abashidze estates.
In 1757, Levan, together with the influential Georgian grandee Rostom, Duke of Racha, joined an Ottoman army sent against Solomon.
