Examine the backlash of the Klan, prohibitionists, nativists fundamentalists during the 1920s.

All of these groups shared one thing in common so I will
address them all together.  All of them were concerned with fighting back against the
new ways of the 1920s.  All of these groups felt that the US had, in the 1920s, gone
away from its traditional values and traditional identity.  They wanted to get the US
back on course.  Therefore, they represented a backlash against the new ways of the
1920s.

In the 1920s, America seemed to be changing.  There
were many more immigrants than there had been in a long time.  There were the flappers
and other evidence of new values.  There was a new lifestyle that was centered around
entertainment rather than work.

Because of these changes,
the groups you mention were unhappy.  They all rallied to try to push the US back to
being a more traditional society.
