With their power growing increasingly stronger, Teimuraz and Erekle soon repudiated their allegiance to the Persian suzerain. Nader Shah ordered 30,000 Persian troops to move into Georgia and entrusted a Georgian convert (and a former anti-Persian leader) Amilakhvari with the punitive operation. The shah was, however, murdered in 1747, and his empire became engulf into complete chaos. The rulers of Kartli and Kakheti took advantage of the situation and expelled all Persian garrisons from their kingdoms. From 1749 to 1750, they checked several attempts of Persian pretenders to create their powerbase in the eastern Transcaucasia, and made the neighbouring khanates of Yerevan, Ganja, and Nakhichevan their tributaries. He fought then against the Dagestani clansmen who frequently raided the Georgian marchlands, but without complete success.
