Document 8: Dictator novel: The dictator novel (Spanish: novela del dictador ) is a genre of Latin American literature that challenges the role of the dictator in Latin American society. The theme of "caudillismo"—the régime of a charismatic "caudillo", a political strongman—is addressed by examining the relationships between power, dictatorship, and writing. Moreover, a dictator novel often is an allegory for the role of the writer in a Latin American society. Although mostly associated with the Latin American Boom of the 1960s and 1970s, the dictator-novel genre has its roots in the nineteenth-century novel "Facundo" (1845), by Domingo Faustino Sarmiento. As an indirect critique of Juan Manuel de Rosas's dictatorial régime in Argentina, "Facundo" is the forerunner of the dictator novel genre; all subsequent dictator novels hearken back to it. As established by Sarmiento, the goal of the genre is not to analyze the rule of particular dictators, or to focus on historical accuracy, but to examine the abstract nature of authority figures and of authority in general.

Document 11: Glengarry Glen Ross (film): Glengarry Glen Ross is a 1992 American drama film, adapted by David Mamet from his 1984 Pulitzer Prize- and Tony-winning play of the same name, and directed by James Foley. The film is set in either New York City or Chicago, and was filmed in New York City.

Document 12: El Señor Presidente: "El Señor Presidente" (Mister President) is a 1946 novel written in Spanish by Nobel Prize-winning Guatemalan writer and diplomat Miguel Ángel Asturias (1899–1974). A landmark text in Latin American literature, "El Señor Presidente" explores the nature of political dictatorship and its effects on society. Asturias makes early use of a literary technique now known as magic realism. One of the most notable works of the dictator novel genre, "El Señor Presidente" developed from an earlier Asturias short story, written to protest social injustice in the aftermath of a devastating earthquake in the author's home town.
Document 13: Glengarry Glen Ross: Glengarry Glen Ross is a play by David Mamet that won the Pulitzer Prize in 1984. The play shows parts of two days in the lives of four desperate Chicago real estate agents who are prepared to engage in any number of unethical, illegal acts—from lies and flattery to bribery, threats, intimidation and burglary—to sell undesirable real estate to unwitting prospective buyers. It is based on Mamet's experience having previously worked in a similar office.
Document 14: I, the Supreme: I, the Supreme (orig. Spanish "Yo el supremo") is a historical novel written by exiled Paraguayan author Augusto Roa Bastos. It is a fictionalized account of the nineteenth-century Paraguayan dictator José Gaspar Rodríguez de Francia, who was also known as "Dr. Francia." The book's title derives from the fact that Francia referred to himself as "El Supremo" or "the Supreme." The first in a long line of dictators, the Supreme was a severe, calculating despot. The central themes of the novel are power and language and the relation between the two. The Supreme believes himself to be above all power and history: "I don't write history. I make it. I can remake it as I please, adjusting, stressing, enriching its meaning and truth." Yet this assertion is constantly challenged by the very fact that while he achieves power by means of writing and dictating, these very same methods can be used by others to dispute his authority. Not even his own identity, represented by the personal pronoun "I", is safe and can easily be usurped as is demonstrated by the incident of the pasquinade. Language, as powerful as it is, can never be controlled and can just as easily be used as an instrument of coercion as an instrument of resistance.
Document 15: Roberto Bolaño: Roberto Bolaño Ávalos (] ; 28 April 1953 – 15 July 2003) was a Chilean novelist, short-story writer, poet and essayist.

"The New York Times" described him as "the most significant Latin American literary voice of his generation".
