Heraclius I of Kakheti

In 1675, Archil conflicted with the shah's government, abandoned Kakheti and defected to the Ottoman Empire. Prince Nicholas capitalized on the ensuing turmoil, returned for a second time and was proclaimed as King of Kakheti Heraclius (Erekle) I. Earlier, in 1666, shah Suleiman I had succeeded Abbas II on the Iranian Safavid throne. In 1674, Suleiman I asked him to decisively end his stay in Russia,[2] ordered him to Isfahan and promised to confirm him as king if Heraclius apostatized to Islam. The king refused to become Muslim and the shah's subject, citing the oath of allegiance given by his ancestor, Alexander II of Kakheti (r. 1574–1605), to Feodor I of Russia. Hence, he was deprived of the crown, being allowed, however, to settle to Isfahan. Kakheti was subsequently under direct Safavid rule.[2]

In 1688, when the government of Iran declared its recalcitrant subject George XI of Kartli deposed, Heraclius acceded to the shah's pressure. He converted to Islam[3] assuming the title of Nazar Alī Khān in 1676. In reward, Heraclius was confirmed as King of Kartli and given a Persian army to win over the crown. To buttress Heraclius's authority, the shah appointed 'Abbās-qolī Khan, formerly a beglarbeg of Ganja, as Persian viceroy in Kakheti (residing at Qara-Agach). The khan failed, however, to prevent George XI from staging a comeback in 1691 and blockading Heraclius (Nazar Alī Khān) in Tiflis, his capital. It was not until 1696 that George admitted defeat and came to Isfahan to offer his submission to the new shah, Soltan Hosayn.

At the same time, the shah grew increasingly dissatisfied with Nazar Alī Khān's administration. Having spent most of his life in Russia and Iran, his lack of knowledge of Georgian national traditions he had already estranged his subjects. A vacillating ruler, addicted to strong drink, though capable at times of being brave, philanthropic and reformist, he never really achieved a firm control of his possessions, or made himself popular with the populace of Kakheti. Meanwhile, George XI managed to gain the favor of Shah Hosayn and was reconfirmed as King of Kartli in 1703, while Nazar Alī Khān was removed from the throne and ordered to Isfahan where he was invested by Hosayn as King of Kakheti and appointed the commander of the shah's personal guard. He was never able to return to his kingdom, however, and died at the Persian capital in 1710, being succeeded on the throne by his son, David II (Imām Qulī Khān), who had run Kakheti during Nazar Alī Khān's absence at Isfahan.
