Ekaterine Dadiani, Princess of Mingrelia

Ekateriné's father, Prince Alexander Chavchavadze

Her spouse, David Dadiani, Prince of Mingrelia

Ekateriné was born to the distinguished Chavchavadze noble family from Eastern Georgia. Her father was Prince Alexander Chavchavadze, a noted Georgian general and godson of Catherine the Great of Russia.[1] Her mother was Princess Salomé Orbeliani, a great-granddaughter of Erekle II (Heraclius II) of Eastern Georgia. Her elder sister Princess Nino married the famous Russian playwright, composer and diplomat Aleksandr Griboyedov, while her younger sister Princess Sophie was married to Count Alexandr Nikolai, the minister of education of Imperial Russia.[2]

On December 19, 1838, Ekateriné married the Hereditary Prince of Mingrelia, David Dadiani. In 1840, he became ruler of the principality upon the retirement of his father, Levan V Dadiani.[3]

In August 1853, David died and Ekateriné quickly assumed the responsibilities of her late husband, rising from relative obscurity. Recognizing her as regent of Mingrelia on behalf of her elder son, Prince Niko,[3] Nicholas I of Russia assigned her a regency council which included her late husband's brothers, Prince Grigol Dadiani and Prince Konstantin Dadiani.

During the Crimean War, the Turks sent a considerable force to Mingrelia, occupying significant parts of the principality and forcing Ekateriné to flee for security reasons. She soon received a threatening letter from the commanding Turkish general Omar Pasha demanding her surrender, as well as the transfer of her son's principality to the Ottoman Empire. Refusing to dignify Pasha's letter with a response, Ekateriné assumed control of the Mingrelian forces and organized successful counter-attacks that inflicted serious damage on the invading Turks.

The Crimean War soon ended in 1856 with the Treaty of Paris and Ekateriné was reinstated as regent, receiving an invitation to the coronation of Emperor Alexander II of Russia. She attended the ceremony with her children, as well as her sister, Nino. According to the Russian memoirist K.A. Borozdin, Ekateriné retained "the luster of her beauty" and looked extraordinary in her "original and richly decorated costume." The memoirist, like many others in modern-day Georgia, refers to her as the "Mingrelian Queen" and states that at the coronation ball, everyone was "delighted with [Ekateriné], her sister, children, and entourage."

In 1856, Ekateriné left the Mingrelian principality to General George Dadiani and moved to live in Tsarskoe Selo, the residence of the Russian Imperial Family, where she became one of the "ladies of the court." In 1857, she was forced to return to Georgia because of the peasant uprising organized by a Mingrelian smith, Uta Miqava. On May 12, the rebels took control of the province's capital Zugdidi, forcing Ekateriné to request help from Russia. Having already effectively annexed Eastern Georgia, Russia eagerly intervened, subdued the uprising, and asked Ekateriné to move to Saint Petersburg on the pretext of facilitating her children's education and upbringing there. Her departure and the establishment of a "temporary" Russian military authority in Mingrelia marked the de facto abolition of the principality.[3]

After moving to Russia, Ekateriné kept her private salon in Tsarskoe Selo open to the Georgian and Russian intelligentsia. After living there for nearly ten years, she moved to Paris, where her daughter Princess Salomé already lived with her French husband, Prince Achille Murat. In the final years of her life, Ekateriné moved back to Western Georgia, then officially part of the Russian Empire, and lived there to the end. She was interred in the medieval Eastern Orthodox monastery of Martvili.
