Count Grigory Grigoryevich Orlov (1734–1783), who created for his family such an illustrious Russian history, was the son of Gregory Orlov, governor of Great Novgorod. He was educated in the corps of cadets at St Petersburg, began his military career in the Seven Years' War, and was wounded at Zorndorf. While serving in the capital as an artillery officer he caught the fancy of Grand Duchess Catherine Alekseyevna, and was the leader of the conspiracy which resulted in the dethronement and death of her husband Peter III (1762).
