World War I

Explanation:

The Great Migration was the movement out of the South of the United States by millions of African-Americans during the first half of the 20th century. They left the rural South and migrate towards the urban Northeast, Midwest, and West of the country.

The pace of this accelerated with the outbreak of World War I because the industrial parts of the United States needed more workforce in the urban areas.
