Upon what points should I focus if I had to assess the role of Martin Luther King in the context of the constitutional and civil rights issues of...

I would first consult any task description or assignment
requirements before engaging in writing the essay.  Making sure these points are present
in your work is of vital importance.  I think that one of the areas upon which I would
place focus would be the concept of Constitutionality in King's work.  In his speeches
and overall message, Dr. King was successful in making the issue of Civil Rights one of
Constitutional legacy and American History.  Examine the presence of these ideas in his
speech, "I Have a Dream." King does not miss the chance to be able to speak to the idea
that Civil Rights is a part of the American legacy.  It is a part of the condition
through which American History can be recognized.  Dr. King was smart enough to
understand that the patriotism and love for America in the late 1950s and early 1960s
can be "coopted" in a matter of speaking to advance the agenda of Civil Rights.  While
so many other leaders took to denigrating America, King flipped the script and argued
that the idea of Civil Rights is merely an extension of the promises and possibilities
of American History and its Constitution.  In doing so, he is able to make the time
bound difficulty in the concept of Civil Rights come to pass for all
Americans.
