Leonid (Russian: Леонид, Ukrainian: Леонід) is a Russian and Ukrainian form of Leonidas. The name ultimately derives from Greek elements: λέων (leon) meaning "lion" and the patronymic suffix ἴδης (ides), thus conveying the meaning "lion's son" or "lion-like." The name's most famous historical bearer is Leonidas I, the Spartan king who led 300 Spartans in the heroic last stand at the Battle of Thermopylae in 480 BC, as chronicled by Herodotus. In Christian tradition, a 3rd-century saint and martyr named Leonidas of Alexandria, father of the theologian Origen, also bore the name. The Slavic form Leonid emerged through the transmission of the name into Eastern Orthodox cultures. Notable Bearers Leonid Brezhnev (1906–1982) – General Secretary of the Communist Party of the Soviet Union from 1964 to 1982, a period marked by political stagnation and the era of "developed socialism." Leonid Andreyev (1871–1919) – Russian playwright and short-story writer, a leading figure of the Expressionist movement in Russian literature. Leonid Agutin (born 1968) – Russian pop musician and songwriter, widely popular in post-Soviet countries.
