Which novel by Ralph Ellison addresses the struggles of African American identity in the early 20th century?

The novel "Invisible Man" by Ralph Ellison specifically focuses on the struggles of African American identity in the early 20th century. It tells the story of an unnamed protagonist who grapples with his social invisibility and the challenges he faces in a racially divided society. The narrative explores themes of identity, race, and self-perception, capturing the complex realities faced by African Americans during this period. Through a series of experiences and encounters, the protagonist seeks to understand his place in a world that often denies his existence and humanity. This powerful exploration of identity makes "Invisible Man" a pivotal work in American literature, particularly concerning African American experiences.

The other works mentioned, such as "The Stranger," "Inferno," and "Sense and Sensibility," do not directly address the specific context of African American identity in the same way that "Invisible Man" does, focusing instead on different themes, settings, and characters that are not aligned with the central issue of racial identity.
