Grigory Potemkin was involved in the "coup d'état" of 1762. In 1772, Catherine's close friends informed her of Orlov's affairs with other women, and she dismissed him. By the winter of 1773, the Pugachev revolt had started to threaten. Catherine's son Paul had started gaining support; both of these trends threatened her power. She called Potemkin for help—mostly military—and he became devoted to her.
