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.
Battle of the Palaces
The "Battle of the Palaces" occurred in the Russian Empire in the last decade of the reign of Catherine II (1784–1796) and the reign of Paul I (1796–1801), with ripple effects extending into the beginning of the reign of Alexander I. A bitter standoff between Catherine and Paul, her only legitimate son and heir, manifested itself in transient political and ideological conflicts, but also had a lasting, tangible impact on Russian architecture. Both parties materialized their political statements and their understanding of sovereign power in expensive construction projects involving the most illustrious architects of the period – Vasily Bazhenov, Vincenzo Brenna, Charles Cameron, Matvey Kazakov, Giacomo Quarenghi, and Ivan Starov. Catherine's palace projects followed the neoclassical canon of the Age of Enlightenment, while Paul deliberately leaned to emerging Romanticism. Buildings that stylistically fell apart from these programs were demolished or rebuilt without hesitation. The "battle" began in 1785 with the demolition of the main palace in Tsaritsyno, and culminated in 1796 with the demolition of Pella, the largest imperial palace in the Saint Petersburg area.
