Briefly outline what Martin Luther King said in his speech, "I Have a Dream."

I assume that you are asking about King's famous "I Have a
Dream" speech delivered in August of 1963.  The main point that King is making in this
speech is that he believes that America can live up to its ideals by creating a society
in which people of all races are equal.

King starts out by
saying that the Declaration of Independence and the Constitution make promises that are
not being fulfilled.  He says that blacks in America have not had the freedoms that
those documents promise.  He says that their movement is pushing for those freedoms but
that it must do so nonviolently and it must have both whites and blacks working
together.

He then goes on to talk about the aims of the
movement, about what will satisfy the movement.  This is where the most famous parts of
the speech come in.  He says that he will only be satisfied when his dream is fulfilled
and there is equality.  He will only be satisfied, for
example,

when
all of God's children, black men and white men, Jews and Gentiles,
Protestants and Catholics, will be able to join hands and sing in the words of the old
Negro spiritual:

Free at last! Free at
last!

Thank
God Almighty, we are free at
last!
