Read José María Arguedas, Deep Rivers (Perú, c. 1930). This is a complex novel made more difficult by the use of words from the Quechua language (though with a glossary) and the fact that many of the main character’s friends are sometimes referred to by their names, sometimes by their nicknames. But it has several interesting sociological dimensions. (Pick one of these rather than trying to cover them all in a single paper.)
Ethnicity: the complex relations among people of different racial and ethnic groups including the cholos (mestizos), and the relations among people of different social levels within each group.
How do the forces of order (army and Guardia Civil) treat people of different ethnicities?
Gender: the central characters are all male but some of the strongest and most interesting people in the book are women. What does it mean that women lead the insurrection, and how is this perceived by others?
Church: what is the position of the church, especially in the person of the rector, on the turbulence?
