African American history is generally categorized into several key periods: the Transatlantic Slave Trade, the Antebellum period, the Civil War and Reconstruction, the Jim Crow era (including the Great Migration and Red Summer), the Civil Rights Movement, and the modern era of social justice and cultural influence.

The Great Migration was the movement of six million African Americans out of the rural Southern United States to the urban Northeast, Midwest, and West between 1916 and 1970. It fundamentally transformed American culture, politics, and the social structure of major cities like Chicago, New York, and Detroit.

The movement was highly responsive to systemic disenfranchisement, leading to landmark legislation such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965. These laws dismantled legal segregation and provided federal protection for voting rights.

Beyond the famous success of Madam C. J. Walker, other pioneers include Annie Malone (beauty industry), A.G. Gaston (insurance and banking), and Robert Reed Church (real estate). These individuals built empires despite the restrictive laws of the early 20th century.

Taking place during the 1920s and 30s, the Harlem Renaissance was a golden age in African American culture, manifesting in literature, music, stage performance, and art. It helped redefine how the world viewed Black culture and integrated it into the broader American narrative.
