Acmeism, a short‐lived (c. 1911–1921) but significant movement in early 20th‐century Russian poetry, aiming for precision and clarity in opposition to the alleged vagueness of the preceding Symbolist movement. Its leaders, Nikolai Gumilev and Sergei Gorodetsky, founded an Acmeist ‘Poets' Guild’ in 1911, and propounded its principles in the magazine Apollon. The principal poetic luminaries of this school were Anna Akhmatova (1889–1966) and Osip Mandelstam (1891–1938).
