Paul I of Russia
Paul I (; "Pavel Petrovich") ( – ) reigned as Emperor of Russia between 1796 and 1801. Officially, he was the only son of Peter III and Catherine the Great, though Catherine hinted that he was fathered by her lover Sergei Saltykov, who also had Romanov blood, being a descendant of the first Romanov tsar's sister, Tatiana Feodorovna Romanova.
Treaty of Georgievsk
Paul tentatively accepted this offer, but before negotiations could be finalized changed his mind and issued a decree on December 18, 1800 annexing Kartli-Kakheti to Russia and deposing the Bagratids. Paul himself died shortly thereafter. It is said that his successor, Emperor Alexander I, considered retracting the annexation in favor of a Bagratid heir, but being unable to identify one likely to retain the crown, on September 12, 1801 Alexander proceeded to confirm annexation. Meanwhile, King George had died on December 28, 1800, before learning that he had lost his throne. By the following April, Russian troops took control of the country's administration and in February 1803 Tsarevich David Bagrationi was escorted by Russian troops from Tbilisi to St. Petersburg. He was pensioned, joined the Russian Senate, and retained his royal style until May 6, 1833 when he was demoted from "tsarevich" (the Russian equivalent of "batonishvili") to "prince" ("knyaz"), along with other members of the deposed dynasty, following an abortive uprising in Georgia led by David's uncle, Prince Alexandre Bagrationi.
