Answer:
Realism, Regionalism, and Naturalism are intertwined and connected. Their influence has dominated most literature created since 1920, though the movement itself is dated to roughly that point. They are truly American modes of writing.
Realism: rapid industrial growth in America (post-Civil War)
and expansion (transportation improvements); change from agrarian (farming, rural) way of life to urban (cities) existence
Nationalism:
Naturalism: The swell of immigrants in the latter half of the 19th
century, which led to a larger lower class and increased poverty in the cities
The realist believes that people can choose a direction in life
and make choices to shape it.
• The regionalist depicts the mood of society in a particular
region and culture.
• The naturalist believes that human life is determined by
heredity and environment – individuals are without free will
and trapped in predestined lives that they cannot change.
• Their influence has dominated most literature created
since 1920, though the movement itself is dated to
roughly that point.
