Answer:cause:After the Civil War and the Reconstruction era, racial inequality persisted across the South during the 1870s, and the segregationist policies known as “Jim Crow” soon became the law of the land.Southern Black people were forced to make their living working the land due to Black codes and the sharecropping system, which offered little in the way of economic opportunity, especially after crop damage resulting from a regional boll weevil infestation in the 1890s and early 1900s.After the Civil War and the Reconstruction era, racial inequality persisted across the South during the 1870s, and the segregationist policies known as “Jim Crow” soon became the law of the land.Southern Black people were forced to make their living working the land due to Black codes and the sharecropping system, which offered little in the way of economic opportunity, especially after crop damage resulting from a regional boll weevil infestation in the 1890s and early 1900s.
effect:As a result of housing tensions, many Black residents ended up creating their own cities within big cities, fostering the growth of a new urban, African American culture. The most prominent example was Harlem in New York City, a formerly all-white neighborhood that by the 1920s housed some 200,000 African Americans.The Black experience during the Great Migration became an important theme in the artistic movement known first as the New Negro Movement and later as the Harlem Renaissance, which would have an enormous impact on the culture of the era.The Great Migration also began a new era of increasing political activism among African Americans, who after being disenfranchised in the South found a new place for themselves in public life in the cities of the North and West. The civil rights movement directly benefited from this activism.Black migration slowed considerably in the 1930s, when the country sank into the Great Depression, but picked up again with the coming of World War II and the need for wartime production. But returning Black soldiers found that the GI Bill didn’t always promise the same postwar benefits for all.By 1970, when the Great Migration ended, its demographic impact was unmistakable: Whereas in 1900, nine out of every 10 Black Americans lived in the South, and three out of every four lived on farms, by 1970 the South was home to only half of the country’s African Americans, with only 20 percent living in the region’s rural areas. The Great Migration was famously captured in Isabel Wilkerson’s The Warmth of Other Suns: The Epic Story of America’s Great Migration.
