Ekaterine Dadiani, Princess of Mingrelia
Ekateriné Dadiani, Princess of Mingrelia(" née" Chavchavadze; March 19, 1816 August 13, 1882) was a prominent 19th- century Georgian aristocrat and the last ruling princess( as regent) of the Principality of Mingrelia in Western Georgia.
She played an important role in resisting Ottoman influence in her principality and was at the center of Georgian high society, both inside the country and abroad.
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.
Grigol Dadiani
Grigol Dadiani (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.
