In the 1920s, more than 750,000 African Americans left the South, a greater movement of people than had occurred in the Irish potato famine of the 1840s. The large-scale relocation to the Northeast and West brought many other changes with it, as many largely rural people moved into cities for the first time. The majority are from Southern, Eastern and Central Europe, including 4 million Italians and 2 million Jews. Many of them settle in major U.S. cities and work in factories.
