Kingdom of Kartli-Kakheti
The Kingdom of Kartli-Kakheti was created in 1762 by the unification of the two eastern Georgian kingdoms of Kartli and Kakheti. From the early 16th century, according to the 1555 Peace of Amasya, these two kingdoms were under Iranian control. In 1744, Nader Shah granted the kingship of Kartli to Teimuraz II and that of Kakheti to his son Heraclius II, as a reward for their loyalty. When Nader Shah died in 1747, Teimuraz II and Heraclius II capitalized on the instability in Iran proper, and declared de facto independence. After Teimuraz II died in 1762, Heraclius succeeded him as ruler of Kartli, thus unifying the two kingdoms.
Heraclius was able, after centuries of Iranian suzerainty over Georgia, to guarantee the autonomy of his kingdom throughout the chaos that had erupted following Nader Shah's death. He became the new Georgian king of a politically united eastern Georgia for the first time in three centuries. Though Heraclius tendered his de jure submission to the newly established Zand dynasty quickly after the unification in 1762, the kingdom remained de facto autonomous for the next three decades to come. In 1783, Heraclius signed the Treaty of Georgievsk with the Russian Empire, by which he formally laid Kartli-Kakheti's investiture in the hands of the Russian monarch, and made the kingdom a Russian protectorate. Amongst others, this provided the nominal guarantee for protection against new Iranian attempts, or by any others, to conquer or attack eastern Georgia. By the 1790s, a new strong Iranian dynasty, the Qajar dynasty, had emerged under Agha Mohammad Khan Qajar, which would prove pivotal in the history of the short-lived kingdom.
In the next few years, having secured mainland Iran, the new Iranian king set out to reconquer the Caucasus and to re-impose its traditional suzerainty over the region. After Heraclius II refused to denounce the treaty with Russia and to voluntarily reaccept Iran's suzerainty in return for peace and prosperity for his kingdom, Agha Mohammad Khan invaded Kartli-Kakheti, captured and sacked Tbilisi, effectively bringing it back under Iranian control. This was short-lived, however, for Agha Mohammad Khan was assassinated two years later. Heraclius II himself died a year after that.
The following years, which were spent in confusion, culminated in 1801 with the official annexation of the kingdom by Paul I within the Russian Empire during the nominal ascension of Heraclius's son George XII to the Kartli-Kakhetian throne. Following the Russo-Persian War of 1804–1813, Iran officially ceded the kingdom to Russia, marking the start of a Russian-centred chapter in Georgian history.
History
After Nader Shah's death in 1747, Heraclius II and Teimuraz II capitalized on the eruption of chaos in mainland Iran. In the ensuing period Heraclius II made alliances with the khans of the area, established a leading position in the southern Caucasus, and requested Russian aid. In 1762, he succeeded his father as king of Kartli, and with already being king of Kakheti, eastern Georgia thus became politically unified for the first time in three centuries. Around 1760, it had become evident as well that Karim Khan Zand had become the new ruler of Iran. Shortly after, in 1762–1763, during Karim Khan's campaigns in Azerbaijan, Heraclius II tendered his de jure submission to him and received his investiture as vali of Gorjestan, the traditional Safavid office, which by this time however had become an "empty honorific". Karim Khan died in 1779 however, with Persia again being engulfed into chaos.Seeking to remain independent, but also realizing that he would need a foreign protector with regard to his kingdom's foreign policy, King Heraclius II concluded the Treaty of Georgievsk with Russia in 1783, resulting in the transfer of responsibility for defense and foreign affairs in the eastern kingdom, as well as importantly, officially abjuring any dependence on Iran or any other power. However, despite these large concessions made to Russia, Heraclius II was successful in retaining internal autonomy in his kingdom.
Heraclius II's "curiously ambivalent position" in these decades is reflected in the coins issued by him in his realm. Silver coins were struck with the name of Ismail III on it, or with the Zand-style inscription ya karim, whereby an epithet to God was invoked, which actually referred to Karim Khan Zand. These coins were minted in Tbilisi up until 1799 – some twenty years after Karim Khan Zand's death. In the same decades, the copper coins struck at Tbilisi bore three types of iconography; Christian, Georgian, "and even" Imperial Russian. By minting the silver coins with a reference to Karim Khan Zand on it they were usable for trade in Iran, whereas the copper coins, struck for only local use, reflected Heraclius II's political orientation towards Russia.
Court and reign
While Heraclius II's court maintained a certain Persian-type pomp, and he himself dressed in the Persian style as well, he launched an ambitious program of "Europeanization" which was supported by the Georgian intellectual élites; it was not overwhelmingly successful however, because Georgia remained physically isolated from Europe and had to expend all available resources on defending its precarious independence. He strove to enlist the support of European powers, and to attract Western scientists and technicians to give his country the benefit of the latest military and industrial techniques. His style of governing resembled that of contemporary enlightened despots in Central Europe. He exercised executive, legislative, and judicial authority and closely supervised the activities of government departments. Heraclius's primary objective in internal policy was to further centralize the government through reducing the powers of the aristocracy. For this purpose, he attempted to create a governing élite composed of his own agents to replace the self-minded aristocratic lords in local affairs.Qajar invasion
In the last few decades of the 18th century, Georgia had become a more important element in Russo-Iranian relations than some provinces in northern mainland Iran, such as Mazandaran or even Gilan. Unlike Peter I, Catherine, the then ruling monarch of Russia, viewed Georgia as a pivot for her Caucasian policy, as Russia's new aspirations were to use it as a base of operations against both Iran and the Ottoman Empire, both immediate bordering geo-political rivals of Russia. On top of that, having another port on the Georgian coast of the Black Sea would be ideal. A limited Russian contingent of two infantry battalions with four artillery pieces arrived in Tbilisi in 1784, but was withdrawn, despite the frantic protests of the Georgians, in 1787 as a new war against Ottoman Turkey had started on a different front.The consequences of these events came a few years later, when a new dynasty, the Qajars, emerged victorious in the protracted power struggle in Iran. Qajar shah, Agha Mohammad Khan, as his first objective, resolved to bring the Caucasus again fully under the Iranian orbit.
For Agha Mohammad Khan, the re-subjugation and reintegration of Georgia into the Iranian Empire was part of the same process that had brought Shiraz, Isfahan, and Tabriz under his rule. He viewed Georgia, like the Safavids and Nader Shah before him, no different from the provinces in mainland Iran, such as Khorasan. 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. 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 collapse of the Zands, including putting down what in Iranian eyes was seen as treason on the part of the vali of Georgia.
Finding an interval of peace amid their own quarrels and with northern, western, and central Persia secure, the Iranians demanded Heraclius II to renounce the treaty with Russia and to re-accept Persian suzerainty, in return for peace and the security of his kingdom. The Ottomans, Iran's neighboring rival, recognized the latter's rights over Kartli and Kakheti for the first time in four centuries. Heraclius appealed then to his theoretical protector, Empress Catherine II of Russia, asking for at least 3,000 Russian troops, but he was ignored, leaving Georgia to fend off the Iranian threat alone. Nevertheless, Heraclius II still rejected the shah's ultimatum.
Agha Mohammad Khan subsequently crossed the Aras River, and after a turn of events by which he gathered more support from his subordinate khans of Erivan and Ganja, he sent Heraclius a last ultimatum, which he also declined, but, sent couriers to St. Petersburg. Gudovich, who sat in Georgievsk at the time, instructed Heraclius to avoid "expense and fuss", while Heraclius, together with Solomon II and some Imeretians headed southwards of Tbilisi to fend off the Iranians.
With half the number of troops Agha Mohammad Khan had crossed the Aras river, he now marched directly upon Tbilisi, where it commenced into a huge battle between the Iranian and Georgian armies. Heraclius had managed to mobilize some 5,000 troops, including some 2,000 from neighboring Imereti under its King Solomon II. The Georgians, hopelessly outnumbered, were eventually defeated despite stiff resistance. In a few hours, the Iranian king Agha Mohammad Khan was in full control of the Georgian capital. The Persian army marched back laden with spoil and carrying off thousands of captives.
By this, after the conquest of Tbilisi and being in effective control of eastern Georgia, Agha Mohammad was formally crowned Shah in 1796 in the Mughan plain. As the Cambridge History of Iran notes; "Russia's client, Georgia, had been punished, and Russia's prestige, damaged." Heraclius II returned to Tbilisi to rebuild the city, but the destruction of his capital was a death blow to his hopes and projects. Upon learning of the fall of Tbilisi General Gudovich put the blame on the Georgians themselves. To restore Russian prestige, Catherine II declared war on Persia, upon the proposal of Gudovich, and sent an army under Valerian Zubov to the Qajar possessions on April of that year, but the new Tsar Paul I, who succeeded Catherine in November, shortly recalled it.
