What does Homer Barron represent? How importent is it that he is a Yankee? From "A Rose for Emily" by William Faulkner.

In "A Rose for Emily," Homer is a Northerner, as opposed
to a Southerner, and it is very important that he is a
Yankee.

The story presents a South that is still recovering
and changing following the collapse of the Southern economy during and following the
Civil War.

The townspeople represent the new South, the
South after the economy that was based on plantations has
collapsed. 

Emily represents the old South, and she does
not adjust well to the new society.  Emily's holding on to the past, to the way things
were before, is representative of the South holding on to a past that was seen as
glorious.

Homer is from the victorious North.  He is a
Yankee.  He is looked down upon by the townspeople, and Emily is criticized when she is
seen with him.  In the socially conservative South, being seen with a beau in public is
anathema, but being seen with a beau from the North is even worse.  He is seen as
"below" Emily. 

The story is a bit of a microcosm of the
South after the Civil War, and Homer is part of the invading and unwanted
North.
