Final answer:
The Great Migration is the term for the relocation of African Americans from the rural South to urban Northern cities, motivated by the pursuit of jobs, freedom from segregation, and better living conditions. Jazz legend Louis Armstrong was one of the many who moved during this period, becoming an iconic figure in the process.
Step-by-step explanation:
The mass movement of African Americans from the rural South to urban areas in the Midwest and Northeast is known as the Great Migration. This movement was fueled by the desire to find new work opportunities, escape segregation, and create a better life for themselves and their families. Louis Armstrong, who migrated to Chicago during this period, was best known for his influence on Jazz music and is widely regarded as one of the world's greatest trumpeters and vocalists.
The Great Migration led to significant demographic shifts and cultural movements, including the Harlem Renaissance, where African Americans built new lives and identities, expressing themselves through art, music, and literature without fear or shame.
