As the Tsar is packed off to Siberia, exile Vladimir Lenin returns to proclaim a workers' revolution. In America, black soldiers who have served their country in Europe demand their rights at home, while an Austrian war veteran begins to rail against the Jews. Much as he did in 1913, Charles Emmerson offers a panoramic view of the world in upheaval, as women win the vote, jazz becomes the music of choice, and former patent clerk Albert Einstein changes our view of how the universe works. Anecdotal yet vast in scope, this history's cast of characters includes Josephine Baker, Ernest Hemingway, Marcus Garvey, Rosa Luxemburg, Sigmund Freud, André Breton, Benito Mussolini, and Mustafa Kemal.
