What were the conflicts that divided society in the 1920?

America was born from immigrants and during the 1920's it was called a
'melting pot' due to the increase in social, political and economic
differences from all these new races. During the 1920's, America went
through a number of test cases to determine to what extent America was
divided. It was obvious that America was gong through some changes as
it had just emerged from the Great War as the world's leading
superpower. Although there were an immense amount of change in all
aspects of society-socially, politically and economically-there was
evidence that America did want to be united. These encompassed
Prohibition. The first test case America went through was the treaty
of Versailles and the League of Nations. Its outcome would enable us
to see America's view on foreign affairs, mainly to do with Europe.
The influx of immigrants had an effect on society which led to the
Palmer Raids and finally the Sacco and Vanzetti case which exemplified
the statement, 'was America a divided society?'. Also the Great
Migration of blacks showed disunity as the division between WASPs
(White Anglo Saxon Protestants) and the backs grew and also the spread
of the Ku Klux Klan activity spreading with the increase in foreigners
and blacks to new parts of America. Another issue that concerned the
statement was the division of wealth as the WASPs seemed to have the
majority of the wealth with blacks and new immigrants at the bottom of
the pile. Their was also exploitation of the blacks and immigrants by
empire leaders as they were a cheap, unskilled replaceable labour
force.
