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.
Pavlovsk Palace
Catherine the Great died in 1796, and Paul became Emperor. He decided to enlarge Pavlovsk into a palace suitable for a royal residence, adding two new wings on either side of the main building, and a church attached to the south wing. Between 1797 and 1799, he lavished money and the finest materials on Brenna's interiors. The reign of Emperor Paul did not last long. He alienated the nobles, and became increasingly fearful of conspiracies. His fears were justified; the Emperor Paul was murdered by members of his court in 1801, and his son Alexander became Emperor. Pavlovsk Palace became the residence of the Empress Maria Feodorovna (1759–1828), the mother of both Emperor Alexander I of Russia and Emperor Nicholas I of Russia.
