Nino, Princess of Mingrelia
Nino (; 15 April 1772 – 30 May 1847) was a Georgian princess royal ("batonishvili") as a daughter of King George XII of Georgia and princess consort of Mingrelia as the wife of Grigol Dadiani, Sovereign Prince of Mingrelia. After the death of her husband in 1804, Nino was a regent for her underage son, Levan until 1811, and helped bring Mingrelia and Abkhazia, a neighboring principality of her in-laws, under the hegemony of the Russian Empire. In 1811, she retired to Saint Petersburg, where she died at the age of 75. Early life. Princess Nino was  born in Tbilisi as the sixth child of then-Crown Prince George and his first wife, Ketevan Andronikashvili, in 1772, in the lifetime of her reigning grandfather, Heraclius II of Georgia. In 1791, at the age of 19, Nino was married off to Grigol Dadiani, Prince of Mingrelia. Around the same time, Grigol's sister Mariam wed Nino's cousin, King Solomon II of Imereti. These marriages were intended to cement an alliance of the Georgian potentates which had been concluded through the efforts of Heraclius II's minister Solomon Lionidze in June 1790. The relations between Solomon and  Grigol quickly became soured over their territorial disputes and, in the period of 1791–1802, Grigol thrice lost throne to Solomon's protégés. Grigol and Nino sought and obtained the protection from the Russian Empire, which had taken over the kingdom of Nino's late father in 1801 and eyed Imereti. By the treaty of 1 December 1803 Mingrelia became part of the Russian Empire as an autonomous principality. On this occasion, Nino received a sable fur coat and ten "arshins" (7.1 m or 23.3 ft) of crimson velvet as the imperial gifts. Regency. Upon Grigol Dadiani's sudden death on  23 October 1804, Princess Nino became more prominently involved in the politics of Mingrelia. She 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 3 November 1804 the Russian government recognized her as the ruler ("pravitselnitsa") of Mingrelia and confirmed her as a regent until her 12-year-old son Levan would reach 20. Levan had been held since 1802 as a hostage by Kelesh Ahmed-Bey Shervashidze, Prince of Abkhazia, in return for his help to Grigol  in the power struggle in Mingrelia. In March 1805 the Russian troops moved into Abkhazia, restored the fort of Anaklia to Mingrelia, and rescued Levan. The regency council under the presidency of Princess Nino also included Prince Niko Dadiani, Bishop Besarion of Chkondidi, the palace majordomo Giorgi Chikovani, and Prince Beri Gelovani, the lord of Lechkhumi. Nino's relations with Niko Dadiani, a highly influential nobleman, and Beri Gelovani, her in-law, were strained. The opponents accused Nino of political machinations and using the council to further her own ends. Furthermore, she was rumored to have been behind the murder  of Prince Grigol, who had been briefly involved with a woman of the Chichua family. These power struggles would continue throughout the period of regency. Princess Nino followed the pro-Russian policy of her late husband. During the Russo-Turkish war of 1806–12, she took command of the Mingrelian troops which joined the Russians in capturing the Black Sea fortress of Poti from the Ottoman forces in 1809. In 1810, Nino sent 1,000 soldiers to the aid of her Abkhazian protégé, Sefer Ali-Bey Shervashidze, who deposed his pro-Ottoman brother, Prince Aslan-Bey, and brought Abkhazia under the Russian  protectorate. Retirement to Russia. In 1811, Nino was sidelined from the government of Mingrelia. She was recalled to St. Petersburg, where she was appointed a "statsdame" and decorated with the Grand Cross of the Order of St. Catherine. Her younger son, Giorgi, and the Abkhazian heir, Dimitri, accompanied her to the imperial capital and were enlisted in the Cadet Corps for military education. Early in 1820, when Nino was vacationing at Georgiyevsk, Giorgi fell under the suspicion of collaborating with the rebels in Imereti, whom his elder brother, Levan, fought in the Russian ranks. Nino was escorted to Ryazan, but  she was later allowed to return to St. Petersburg, where she spent the rest of her life and died on 31 May 1847. She was interred at the Church of St. John Chrysostom, Alexander Nevsky Lavra. Princess Nino's only surviving portrait, produced by an unknown artist during her St. Petersburg years, was purchased in 2010 by the Australian entrepreneur Victor Greenwich Dadianov, a scion of the Dadiani dynasty and Honorary Consul-General of Georgia in Sydney, at one of the auctions of Europe, and was presented by him to the Dadiani Palaces Museum in Zugdidi, Georgia. Children. Prince Grigol  and Princess Nino had six children, two sons and four daughters:
