How did World War I affect the Great Migration?

Men were needed to work in war-related industries in the North. Most white men were being drafted, while draft boards were so racist that blacks tended to be excluded, and available to fill the industrial jobs.

The Great Migration, or the relocation of more than 6 million African Americans from the rural South to the cities of the North, Midwest and West from 1916 to 1970, had a huge impact on urban life in the United States.
