Countee Cullen was a prominent African-American poet during the Harlem Renaissance, a cultural and artistic movement that took place in the 1920s and 1930s in Harlem, New York City. Cullen's poetic work addressed themes of race, identity, and the African-American experience in America.

Born in 1903, Cullen was raised in Harlem and went on to study at New York University and later at Harvard University. He became known for his mastery of poetic forms and his ability to blend classical poetic techniques with African-American themes.

Some of Cullen's most famous works include poems like "Yet Do I Marvel," "Heritage," and "Incident." His poetry often explored the complexities of being a Black person in a predominantly white society, while also celebrating the richness of African-American culture and history.

Cullen's contributions to Black history and literature have had a lasting impact, and he is remembered as one of the leading voices of the Harlem Renaissance.
