Senghor created the concept of Négritude, an important intellectual movement that sought to assert and to valorize what they believed to be distinctive African characteristics, values, and aesthetics. This was a reaction against the too strong dominance of French culture in the colonies, and against the perception that Africa did not have culture developed enough to stand alongside that of Europe. Building upon historical research identifying ancient Egypt with black Africa, Senghor argued that sub-Saharan Africa and Europe are in fact part of the same cultural continuum, reaching from Egypt to classical Greece, through Rome to the European colonial powers of the modern age. Négritude was by no means—as it has in many quarters been perceived—an anti-white racism, but rather emphasized the importance of dialogue and exchange among different cultures
King's efforts led to the 1963 March on Washington, where King delivered his “I Have a Dream” speech. There, he raised public consciousness of the civil rights movement and established himself as one of the greatest orators in U.S. history.
In 1964, King became the youngest person to receive the Nobel Peace Prize for his work to end racial segregation and racial discrimination through civil disobedience and other non-violent means. By the time of his death in 1968, he had refocused his efforts on ending poverty and opposing the Vietnam War, both from a religious perspective.
