'Abdu'llah Beg was the eldest son of Jesse-Khan, a Muslim ruler of Kartli in central and eastern Georgia, by his first wife Mariam née Orbeliani.
Teimuraz made 'Abdu'llah Beg a prince of Somkhiti and Sabaratiano (Kvemo Kartli) with the residence at Samshvilde.
In 1747, Teimuraz made a trip to Iran, leaving his son Erekle II in charge of Kartli and 'Abdu'llah Beg as his lieutenant.
In Teimuraz’s absence, however, 'Abdu'llah Beg attempted a coup, recruited the Dagestani mercenaries and took control of the capital city, Tiflis, with the help of a local Iranian garrison.
Fighting continued into the following year until 'Abdu'llah Beg was finally defeated and Tiflis captured by Erekle's loyal army.
