The Manifesto of the Sixteen (French: "Manifeste des seize" ), or Proclamation of the Sixteen, was a document drafted in 1916 by eminent anarchists Peter Kropotkin and Jean Grave which advocated an Allied victory over Germany and the Central Powers during the First World War.
 At the outbreak of the war, Kropotkin and other anarchist supporters of the Allied cause advocated their position in the pages of the "Freedom" newspaper, provoking sharply critical responses.
 As the war continued, anarchists across Europe campaigned in anti-war movements and wrote denunciations of the war in pamphlets and statements, including one February 1916 statement signed by prominent anarchists such as Emma Goldman and Rudolf Rocker.
