Orlov, Grigori Grigoryevich, Count
Grigori Grigoryevich Orlov, Count (grĬgô´rē grĬgôr´yəvĬch, ərlôf´), 1734–83, Russian nobleman. One of the first lovers of Catherine II, he and his brother led the conspiracy that deposed Peter III and put her on the throne. Although the empress was deeply in love with him and owed her power to him more than to any other, he did not have a decisive voice in state affairs. He was later supplanted by other favorites, notably Potemkin. Catherine gave him high military posts but did not act on his plans for the emancipation of the serfs.
