The Day of Affirmation speech (also known as the Ripple of Hope speech) was a speech given by Robert F. Kennedy to National Union of South African Students members at the University of Cape Town, South Africa, on June 6, 1966, on the University's "Day of Reaffirmation of Academic and Human Freedom". Kennedy was at the time the junior U.S. Senator from New York. It is often considered his greatest and most famous speech.
In the speech Kennedy talked about individual liberty, apartheid, and the need for civil rights in the United States at a time when the American civil rights movement was ongoing.
