For Agha Mohammah Khan, the resubjugation and reintegration of Georgia into the Iranian Empire was part of the same process that had brought Shiraz, Isfahan, and Tabriz under his rule.[15] He viewed, like the Safavids and Nader Shah before him, the territories no different than the territories in mainland Iran. Georgia was a province of Iran the same way Khorasan was.[15] As the Cambridge History of Iran states, its permanent secession was inconceivable and had to be resisted in the same way as one would resist an attempt at the separation of Fars or Gilan.[15] It was therefore natural for Agha Mohammad Khan to perform whatever necessary means in the Caucasus in order to subdue and reincorporate the recently lost regions following Nader Shah's death and the demise of the Zands, including putting down what in Iranian eyes was seen as treason on the part of the wali of Georgia.[15] Finding an interval of peace amid their own quarrels and with northern, western, and central Persia secure, the Persians demanded Heraclius II to renounce the treaty with Russia and to reaccept Persian suzerainty,[18] in return for peace and the security of his kingdom. The Ottomans, Iran's neighboring rival, recognized the latters rights over Kartli and Kakheti for the first time in four centuries.[19] Heraclius appealed then to his theoretical protector, Empress Catherine II of Russia, pledging for at least 3,000 Russian troops,[19] but he was not listened, leaving Georgia to fend off the Persian threat alone.[20] Nevertheless, Heraclius II still rejected the Khan's ultimatum.[21]
