Answer:
The Great Migration of African Americans was the massive migration of about 6 million blacks from the agricultural southern states to the industrial cities of the north and west of the nation, which took place from 1910s the to the 1940s.
With the arrival of the Industrial Revolution in America and the expansion of the railroad, many African-American workers from the south of the country, who were exploited by their white employers, discriminated against by the conservative society of the south, and segregated by the Jim Crow Laws, saw the possibility of fleeing from that environment to a much more favorable one, with decent jobs and egalitarian social conditions.
This possibility of change would not have been possible without the technological advances that emerged with the Industrial Revolution: without the advance of steam engines, locomotives would not have been able to extend so many distances and therefore African Americans would have had less chance of transporting. In addition, the large number of industries that were established in the north did so as a result of the technological advances that had taken place in those years, generating a greater supply of employment and attracting a large amount of labor towards the cities.
Therefore, it is possible to affirm that without the Industrial Revolution and its improvements in technology, it would have been impossible for the Great Migration to occur, since this was an indirect social consequence of the Industrial Revolution.
