American Renaissance
The American Renaissance was a period of American architecture and the arts from 1876 to 1917, characterized by renewed national self-confidence and a feeling that the United States was the heir to Greek democracy, Roman law, and Renaissance humanism. The era spans the period between the Centennial Exposition (celebrating the 100th anniversary of the signing of the Declaration of Independence) and the United States' entry into World War I.
Harlem Renaissance
Certain aspects of the Harlem Renaissance were accepted without debate, and without scrutiny. One of these was the future of the "New Negro". Artists and intellectuals of the Harlem Renaissance echoed American progressivism in its faith in democratic reform, in its belief in art and literature as agents of change, and in its almost uncritical belief in itself and its future. This progressivist worldview rendered Black intellectuals—just like their White counterparts—unprepared for the rude shock of the Great Depression, and the Harlem Renaissance ended abruptly because of naive assumptions about the centrality of culture, unrelated to economic and social realities.
