How does "Song for a Dark Girl" by Langston Hughes relate to the Modernism time period?

The poem relates to Modernism in a couple of ways.  The
most dominant connection is the alienation that is articulated by the speaker.  The
feeling of alienation that the speaker experiences throughout the poem is reflective of
the division of consciousness articulated in Modernism.  The matter of fact manner in
which the opening lines depict the hanging of a loved one, along with the questioning of
religion's purpose in such a setting is akin to the Modernist idea of how the
protagonist is fundamentally different from the rest of the world.  The speaker might be
saying these elements without emotion, but their experiences of seeing someone they love
bruised, beaten, and hung from a tree makes them separate from all other societies.  At
the same time, there is fundamental disconnect between the supposed progress of the
world and the experiences of the speaker.  Something is adrift in a world that shows
advancement and progress, but still features loved ones hanging from trees without much
in way of redemption being offered.  This, too, is a Modernist
sentiment.
