Explanation:

Harlem Renaissance was a period during which African-American people started exploring their history and re-identifying themselves through art and philosophy.

It started in Harlem, part of New York, and it is marked by the development and blossoming of rich Afro-American culture. It was a cultural, artistic, and intellectual movement. Many black people produced amazing works of art, music, books, fashion, etc. that were largely focused on their relationship with the history and heritage, as well as reconceptualization of their racial identity. It was a way to express themselves breaking the stereotypes and shame that was created in the society beforehand. It also largely influenced the civil rights movement.
