Grigol Dadiani

Grigol Dadiani (გრიგოლ დადიანი; 1770 – 23 October 1804), of the House of Dadiani, was Prince of Mingrelia from 1788 to 1804, with intermissions from 1791 to 1794 and in 1802 when his position was filled by his rivaling brothers. His rule was marred by the long-standing struggle between the Imeretian crown seeking to subdue Mingrelia and Mingrelian efforts to win full independence, a continuation of the conflict which had plagued western Georgia for centuries. Grigol's rapprochement with the expanding Russian Empire resulted in Mingrelia becoming, in 1804, a Russian subject with a degree of internal autonomy under the Dadiani dynasty, an arrangement which remained in place until 1856.

Early rule
Grigol was the eldest son of Katsia II Dadiani by his third wife Anna Tsulukidze. In 1788, Grigol, then 18-year-old, succeeded on the death of his father as prince-regnant of Mingrelia. King David II of Imereti made use of his youth to advance his claims to Mingrelia and, notwithstanding important services rendered by Katsia II Dadiani, invaded the principality. Grigol took to Lechkhumi, a highland district disputed between Imereti and Mingrelia, whose loyalty then lay with Dadiani. King Heraclius II of Kartli–Kakheti intervened militarily and helped defeat David at Matkhoji in July 1789, thereby restoring Grigol to Mingrelia and securing the crown of Imereti for his grandson, Solomon II. This was followed by the 1790 treaty, which established a loose confederation of Georgian kings and princes. Grigol then married Heraclius's granddaughter Princess Nino, while Grigol's sister Mariam became Solomon II's wife.

Conflict with Imereti
The unresolved dispute over Lechkhumi, however, quickly led to a renewed conflict between Imereti and Mingrelia. In 1791, Solomon II of Imereti succeeded in ousting Grigol in favor of his own younger brother, Manuchar. Grigol fled to the Ottoman pasha of Akhaltsikhe. King Heraclius II's mediation failed and Grigol was detained on his arrival for negotiations in Kutaisi, Imereti's capital. He soon managed to escape with the help of his uncle, Giorgi Dadiani, and Kaikhosro Gelovani, governor-general of Lechkhumi, and entrenched himself in the fortress of Nogi in Mingrelia, which Solomon failed to take and fell back to Kutaisi. As a result, the king had to recognize Grigol as prince of Mingrelia, who, in his turn, conceded the fiefdom of Salipartiano to his estranged brother Manuchar, Solomon's protégé. Grigol, however, found his authority limited by rising influence of Kaikhosro Gelovani, whom he had murdered in 1799.

Peace with Imereti did not endure. In 1802, Solomon invaded Lechkhumi, defeated Dadiani at Salkhino, and had him replaced by another brother, Tariel. Grigol quickly regained his position, but he had to concede the fort of Anaklia and to surrender his own son and heir, Levan, as an honorary hostage to Kelesh Bey, ruler of Abkhazia, in exchange of received support.

Mingrelia joins Russia
By that time, a momentous event had taken place in Georgia; in 1801, the Russian Empire annexed the eastern Georgian kingdom of Kartli and Kakheti. In October 1802, Grigol Dadiani approached the Russian commander in Georgia, Prince Tsitsianov, expressing his desire to put himself under Russian protection, provided his and his descendants' rights as rulers of Mingrelia were guaranteed. The Russian diplomats, having secured Ottoman neutrality on the Mingrelian issue, formalized the agreement with Dadiani with the Treaty of Dadichala on 1 December 1803, which was ratified by Tsar Alexander I on 20 March 1804. Dadiani was recognized as Prince of Mingrelia, the legal ruler of "Odishi, Lechkhumi, Svaneti, and Abkhazia", in exchange of Dadiani’s acceptance of the Tsar's suzerainty. The treaty, which would remain in force until 1856, made Mingrelia an autonomous principality within the Russian Empire and a cornerstone of Russian imperial power-building in western Caucasus. On the occasion of the conclusion of the treaty, Grigol was awarded the Order of Saint Alexander Nevsky, which was returned by the Russian authorities to the Imperial Administration of Orders after the prince's death, ignoring Princess Nino's request to leave it in the Dadiani family.

In 1804, Solomon II followed Dadiani's suit, accepting the Russian suzerainty at gunpoint. Both rulers were reassured by the Russians regarding the ownership of Lechkhumi, but the disputed district remained under Dadiani's control. Grigol then tried to exploit Russia's increasingly tense relations with Imereti and went so far as to petition the Tsar to depose Solomon II as king and to replace him with his cousin, Prince Ioann of Georgia. The Russian government, still hoping to bend Solomon into submission, immediately disavowed the plan.

Death and aftermath
As the renewed crisis over Lechkhumi was unfolding, Grigol Dadiani died, unexpectedly, at Muri in October 1804. He was buried at the Martvili Monastery. Dadiani's widow, Princess Nino, who assumed regency for Grigol's heir, Levan, immediately accused the rival nobles of having poisoned the prince and requested from the Russian commander in Georgia, Prince Pavel Tsitsianov, to have an inquiry into her husband's murder. On the other hand, Nino's opponents spread rumors that the princess herself was behind the murder of Prince Grigol, who had been briefly involved with a woman of the Chichua family. Tsitsianov himself exploited the suspicion of homicide to remove Grigol's treating doctor, the Italian Capuchin missionary Nicola di Rutigliano, who was suspected of anti-Russian intrigues.

Family
Grigol Dadiani and his wife, Nino, daughter of George XII of Georgia, had two sons and four daughters:


 * Princess Ketevan (born 1792), who married first Manuchar Shervashidze, Prince of Samurzakano (died 1813), and then, in 1823, Rostom-Bey, son of Kelesh Ahmed-Bey Shervashidze, Prince of Abkhazia. A grandson of her first marriage was Prince Giorgi Shervashidze (1847–1918), Governor of Tiflis, known for his persecution of the doukhobors in 1895.
 * Prince Levan (1793–1846), Sovereign Prince of Mingrelia (1804–1840).
