November 1918: A German Revolution (German: "November 1918, eine deutsche Revolution" ) is a tetralogy of novels by German writer Alfred Döblin about the German Revolution of 1918–1919.
 The four volumes—Vol.
 I: "Bürger und Soldaten" ("Citizens and Soldiers"), Vol.
 II "Verratenes Volk" ("A People Betrayed"), Vol.
 III, "Heimkehr der Fronttruppen" ("Return of the Frontline Troops"), and Vol.
 IV, "Karl und Rosa" ("Karl and Rosa")—together comprise the most significant work from Döblin's period of exile (1933–1945).
 The work was highly praised by figures such as Bertolt Brecht, and critic Gabriele Sander has described the tetralogy as representing the culmination of Döblin's work in the genre of the historical novel.
Wadzeks Kampf mit der Dampfturbine ("Wadzek's Struggle with the Steam Turbine") is a 1918 comic novel by the German author Alfred Döblin.
 Set in Berlin, it narrates the futile and often delusional struggle of the eponymous industrialist Wadzek against Rommel, his more powerful competitor.
 In its narrative technique and its refusal to psychologize its characters, as well as in its vivid evocations of Berlin as a modern metropolis, "Wadzeks Kampf mit der Dampfturbine" has been read as a precursor to Döblin's better-known 1929 novel "Berlin Alexanderplatz".
Wallenstein is a 1920 historical novel by German author Alfred Döblin.
 Set in Central Europe during the Thirty Years War, the novel's plot is organized around the polar figures of Ferdinand II, Holy Roman Emperor, on the one hand, and Albrecht von Wallenstein, on the other.
 Döblin's approach to narrating the war differed from prevailing historiography in that, rather than interpreting the Thirty Years War primarily as a religious conflict, he portrays it critically as the absurd consequence of a combination of national-political, financial, and individual psychological factors.
 Döblin saw a strong similarity between the Thirty Years War and the First World War, during which he wrote "Wallenstein".
 The novel is counted among the most innovative and significant historical novels in the German literary tradition.
 In large part, contemporary critics found the novel to be difficult, dense, and chaotic—a reception Döblin discussed in his 1921 essay "The Epic Writer, His Material, and Criticism"—yet writers such as Lion Feuchtwanger, Franz Blei, and Herbert Ihering praised "Wallenstein" for its formal innovation, poetic language, epic scope, and bold departure from other German writing of the time.
 Despite the novel's difficulty, the critical consensus was that "Wallenstein" was a major achievement and confirmed the promise seen in Döblin's earlier historical novel, "The Three Leaps of Wang Lun".
The Three Leaps of Wang Lun ("Die drei Sprünge des Wang-lun") is a historical novel by German author Alfred Döblin that narrates upheaval and revolution in 18th-century China.
 Published in 1916 (although back-dated to 1915), this epic historical novel was Döblin's third novel (although it was the first to be published as a book), and garnered him the Fontane Prize.
 Favorably received by critics, who praised its detailed and exotic depictions of China, it was a literary breakthrough for Döblin.
 "Wang Lun" also had an influence on younger German writers, including Lion Feuchtwanger, Anna Seghers, and Bertolt Brecht; for the latter, "Wang Lun" provided an impulse for the development of the theory of epic theatre.
 In commercial sales, it is Döblin's most successful novel after "Berlin Alexanderplatz".
 The title of the novel refers to the rebel leader Wang Lun.
César Abraham Vallejo Mendoza (March 16, 1892 – April 15, 1938) was a Peruvian poet, writer, playwright, and journalist.
 Although he published only three books of poetry during his lifetime, he is considered one of the great poetic innovators of the 20th century in any language.
 He was always a step ahead of literary currents, and each of his books was distinct from the others, and, in its own sense, revolutionary.
 Thomas Merton called him "the greatest universal poet since Dante".
 The late British poet, critic and biographer Martin Seymour-Smith, a leading authority on world literature, called Vallejo "the greatest twentieth-century poet in "any" language."
 He was a member of the intellectual community called North Group formed in the Peruvian north coastal city of Trujillo.
The Copa Ciudad de Trujillo, is an international exhibition football competition hosted in Trujillo, Peru since 2010.
 It features four teams: Trujillo's major team Universidad César Vallejo, and guest teams from Colombia (in 2010 and 2011), Ecuador (in 2010), and Peru (in 2010 and 2011).
 All matches are played at the Estadio Mansiche in Trujillo, the home stadium of the Universidad César Vallejo.
