on February 20, 1810. Defeated during a subsequent rebellion to regain power, he died in exile in Trabzon, Ottoman Turkey, in 1815. Russian rule over Georgia was eventually acknowledged in various peace treaties with Iran and the Ottomans and the remaining Georgian territories were absorbed by the Russian Empire in a piecemeal fashion in the course of the 19th century. Bagrationi in Russia In the Russian Empire, the Bagrationis became a prominent family of aristocrats. The most famous was Prince Pyotr Bagration, a great-grandson of King Jesse of Kartli who became a Russian general and hero of the Patriotic War of 1812. His brother Prince Roman Bagration also became a Russian general, distinguishing himself in the Russo-Persian War (1826–1828), and was the first to enter Yerevan in 1827. Roman Bagration was also known for his patronage of the arts, literature and theatre. His home theater in Tbilisi was regarded as one of the finest in the Caucasus. His son Prince Pyotr Romanovich Bagration became governor of the Tver region and later governor-general of the Baltic provinces. He was also a metallurgic engineer known for the development of gold cyanidation in Russia. Prince Dmitry Petrovich Bagration was a Russian general who fought in World War I in the Brusilov Offensive and later joined the Red Army. Bagrationi today The majority of the Bagrationi family left Georgia after the Red Army took over Tbilisi in 1921. Mukhrani branch The House of Mukhrani is the most senior patrilinear branch of the Bagrationi dynasty, descending directly from King Constantine II of Georgia. Originally a cadet branch of the former Royal House of Kartli, they became the genealogically seniormost line of the Bagrationi family in the early 20th century; and although this elder branch had lost the rule of Kartli by 1724, it retained the Principality of Mukhrani until its annexation by Russia, along with Kartli-Kakheti, in 1800. This branch of the family is related to the House of Borbón, the House of Wittelsbach, the House of Habsburg-Lorraine, and the House of Romanov. A member of this branch, Princess Leonida Georgievna Bagration-Moukhransky, married Vladimir Cyrillovich, Grand Duke of Russia, and became the mother of one of the claimants to the Romanov legacy, Maria Vladimirovna, Grand Duchess of Russia. The overwhelming majority of regnant and non-regnant Royal Houses recognize Prince Davit's claim to the Headship of the Royal House of Georgia. In 1942 Prince Irakli (Erekle)
