Please give background information about "A Rose for Emily".

Faulkner's "A Rose for Emily," like much of Faulkner's fiction, occurs in the South following the Civil War.  The war devastated the South's economy, and the town is trying to recover from that devastation.

Emily would have grown up in the ante-bellum South, before the Civil War.  That was when her family was wealthy, we assume.  She is poor in the story's present, after the economy has crashed. 

This setting feeds into her refusal to give up the past.  She clings to her father, to her home, to Homer, as many in the South following the Civil War tried to hold on to a past they saw as glorious.
