Second Great Migration (African American)
The Second Great Migration was the migration of more than five million African Americans from the South to the North, Midwest and West. It took place from 1941, through World War II, and lasted until 1970. It was much larger and of a different character than the first Great Migration (1910–1940). Some historians prefer to distinguish between the movements for those reasons.
In the Second Great Migration, more than five million African Americans moved to cities in states in the North, Midwest and West, including many to California, where Los Angeles, Oakland, and Long Beach offered many skilled jobs in the defense industry. Most of these migrants were already urban laborers who came from the cities of the South. They were better educated and had superior skills compared to those of non-migrants. In addition, African Americans were still treated brutally in the South, and many sought to escape this.
Urban settlement 
Compared to the more rural migrants of the period 1910-1930, many African Americans in the South were already living in urban areas and had urban job skills before they relocated. They moved to take jobs in the burgeoning industrial cities and especially the many jobs in the defense industry during World War II (WWII). Workers who were limited to segregated, low-skilled jobs in Southern cities were able to get highly skilled, well-paid jobs at California shipyards.
By the end of the Second Great Migration, African Americans had become a highly urbanized population. More than 80 percent lived in cities, a greater proportion than among the rest of American society. Fifty-three percent remained in the Southern United States, while 40 percent lived in the Northeast and North Central states and 7 percent in the West.
While African Americans were often relegated to support roles during WWII, often these roles could be exceedingly hazardous. A munitions explosion at Port Chicago, California, across the bay from San Francisco, claimed the lives of over 200 African Americans in 1944. When some of the workers refused to resume work until conditions were made less hazardous, as many as 50 were tried for mutiny and imprisoned.
Other effects of the Second Great Migration:
- Demographic changes in losing and gaining states;
- African Americans became more unionized;
- African Americans entered the middle class in larger numbers, with the help of skilled industrial jobs;
- African Americans began working in many industrial fields new to them;
- African-American communities in cities contained a range of jobs, professions and classes. The concentrations of populations supported their creation of black-owned businesses, such as insurance, funeral homes, hairdressers and barber shops, and they supported their own doctors and lawyers, as well as their own churches and ministers.
- African Americans developed original religions and Christian movements, such as the Nation of Islam and predominantly-black dominations within the Pentecostal movement.
