Catherine gives birth to her son Paul, securing the Russian succession, in October 1754.
In October 1754, Catherine gave birth to a son, Paul Petrovich, who would later reign as Emperor Paul I of Russia. The birth was of enormous dynastic importance, finally securing the succession after nearly a decade of a strained and childless marriage to Grand Duke Peter that had caused deep anxiety at the imperial court.
Empress Elizabeth, eager to control the upbringing of the future heir, took the infant Paul away from Catherine almost immediately, raising him under her own supervision and severely limiting Catherine's access to her son. This painful separation would shape a lifelong, often distant and complicated relationship between mother and son, one that persisted even after Catherine became empress in her own right.
Rumors swirled for generations about Paul's true paternity, with contemporaries and later historians speculating that Catherine's lover Sergei Saltykov, rather than Peter, may have been his biological father — though definitive proof remains elusive. Regardless, Paul's birth cemented Catherine's position at court by fulfilling her dynastic obligation, buying her political security even as her personal marriage continued to deteriorate. Paul would eventually succeed his mother as emperor in 1796, ruling until his assassination in 1801.
