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.
Until 1722, the order of succession in Russia was based on primogeniture. In 1722 Peter I parted with tradition and enacted the monarch's right (and, in fact, obligation) to name his or her successor at will. The change was followed with a series of palace coups; for most of the remaining 18th century the throne was occupied by women: Catherine I, Anna, Elisabeth, Catherine II. Catherine II ascended to the throne through the murder of her husband, Peter III when their only legitimate son, Paul, was seven years old. Paul retained affection to his late father throughout his life; with age, the feeling mutated into hatred for the mother.
