What is Martin Luther King, Jr.'s claim in his "I Have a Dream" speech?

Speaking
during the march on Washington, D.C.
in 1963, Dr. Martin Luther King, Jr. claims that African
Americans have come
to the nation's capital to cash "a promissory note," a note that
must be
honored or there will be no tranquility in America.

This

"promissory note" is a promise written into the Constitution that all men are

guaranteed the "unalienable rights of life, liberty, and the pursuit of
happiness."
King contends that even though his people were freed by the
Emancipation
Proclamation, they are still not afforded
true freedom because there is a lack of
opportunity under segregation and
police brutality. King contends that "[T]here will be
neither rest nor
tranquility in America until the Negro is granted his citizenship

rights."

At the same time, Dr. King urges his people not to resort
to
acts of hatred. He further urges them to conduct their struggle with
"dignity and
discipline," and to avoid all physical violence.

Dr. Martin Luther King
ends his speech with his famous words "I have
a dream." He speaks of a new vision for
America in which the people of his
race will be afforded equal opportunities and equal justice
under the precept
in the Constitution that "all men are created equal." With this
dream and
"faith" that the "promissory note" will be honored, Dr. King
encourages his
people to continue to pursue the changes necessary in

America.
