During what time period of literature do we place the harlem renaissance?

The Harlem Renaissance is generally considered to have arisen from about 1918 until the mid-1930s. Many of his ideas have lived for much longer. The peak of this was the "flowering of Black literature" with James Weldon Johnson, between 1924 (the year that Opportunity: A Journal of Black Life organized a party for black writers where many white editors were present) and 1929 (the year of fall of the stock market and the onset of the Great Depression).

The Harlem Renaissance embraced the ideology that African-American culture should not be based on European / Caucasian. On the contrary, it should be a reflection of black culture. The result was an explosion of art and music that grew out of the roots of Africa and slavery.
