Battle of Krtsanisi in the context of "Agha Mohammad Khan Qajar"

The Guarded Domains of Iran, alternatively the Sublime State of Iran and commonly called Qajar Iran, Qajar Persia or the Qajar Empire, was the Iranian state under the rule of the Qajar dynasty, which was of Turkic origin, specifically from the Qajar tribe, from 1789 to 1925. The Qajar family played a pivotal role in the Unification of Iran (1779–1796), deposing Lotf 'Ali Khan, the last Shah of the Zand dynasty, and re-asserted Iranian sovereignty over large parts of the Caucasus. In 1796, Agha Mohammad Khan Qajar seized Mashhad with ease, putting an end to the Afsharid dynasty. He was formally crowned as Shah after his punitive campaign against Iran's Georgian subjects.

In the Caucasus, the Qajar dynasty permanently lost much territory to the Russian Empire over the course of the 19th century, comprising modern-day eastern Georgia, Dagestan, Azerbaijan, and Armenia. Despite its territorial losses, Qajar Iran reinvented the Iranian notion of kingship and maintained relative political independence, but faced major challenges to its sovereignty, predominantly from the Russian and British empires. Foreign advisers became powerbrokers in the court and military. They eventually partitioned Qajar Iran in the 1907 Anglo-Russian Convention, carving out Russian and British influence zones and a neutral zone.

Heraclius II, also known as Erekle II (Georgian: ერეკლე II) and The Little Kakhetian (Georgian: პატარა კახი [pʼatʼaɾa kʼaχi]; 7 November 1720 or 7 October 1721 [according to C. Toumanoff] – 11 January 1798), of the Bagrationi dynasty, was the king (mepe) of the Kingdom of Kakheti from 1744 to 1762, and of the Kingdom of Kartli-Kakheti from 1762 until his death in 1798. In the contemporary Persian sources he is referred to as Erekli Khan (ارکلی خان), while Russians knew him as Irakly (Ираклий). Heraclius is the Latinized form of his name.

From being granted the kingship of Kakheti by his overlord Nader Shah in 1744 as a reward for his loyalty, to becoming the penultimate king of the united kingdoms of Kakheti and Kartli in eastern Georgia, his reign is regarded as the swan song of the Georgian monarchy. Aided by his personal abilities and the unrest in Iran following Nader Shah's death, Heraclius established himself as a de facto autonomous ruler, unified eastern Georgia politically for the first time in three centuries, and attempted to modernize the government, economy, and military. Overwhelmed by the internal and external menaces to Georgia's precarious independence and its temporary hegemony in eastern Transcaucasia, he placed his kingdom under the formal Russian protection in 1783, but the move did not prevent Georgia from being devastated by the Persian invasion in 1795. Heraclius died in 1798, leaving the throne to his moribund heir, George XII.
