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
The Harlem Renaissance is generally considered to have spanned from about 1918 until the mid-1930s. Many of its ideas lived on much longer. The zenith of this "flowering of Negro literature", as James Weldon Johnson preferred to call the Harlem Renaissance, took place between 1924 (when "" hosted a party for black writers where many white publishers were in attendance) and 1929 (the year of the stock market crash and the beginning of the Great Depression).
