More than a million Black Southerners left the South in the 1940s, pushed by collapsing cotton economics and Jim Crow, pulled by war jobs, as part of a Second Great Migration of over five million. For the first time the West Coast opened its industrial doors. The wages were a revelation, but the welcome included segregated housing, unions that took dues but not members, and hostile neighbors.
Historians debate how much mechanization pushed versus opportunity pulled, since the mechanical cotton picker spread mainly after the wartime surge. The second emancipation framing is a lens rather than a settled verdict.
