African-American history in the twentieth century is best summarized by both the Civil Rights Movement and the lesser-known Great Migration, in which large numbers of them moved north, west, or overseas, between the years 1910 and 1940. The larger reason for this movement is the Jim Crow laws of the South, in which many of the harmful rules against those parties, who were already affected by the institution of slavery in recent memory, were established. However, this is not the only cause, there are many that span a wide range of reasons: the economic boom of the First World War, geographical mobility and racial antagonism faced on a widespread basis. The actual migration of African Americans themselves is nothing new, as Sarah-Jane Mathieu notes in her work on the topic: “Movement has always characterized the African American experience.”1 Whether it is the voluntary movement north to gain rights , or the pillaging of these people from their homes, the African-American heritage is that of migration. There are actually two Great Migrations, one of which took place in the reconstruction efforts after the Civil War, the other of which took place in the time period described, in the 30 years after 1910. The first in some way acted as a catalyst for the second, with many of the same reasons and notable parallels in both. For example, both had their roots in the socioeconomic problems of the period, with reconstruction and the need for industrial jobs pushing them north, where things were a little more liberal than in the south. Although these two events had many similarities, the Great Migration itself had a much more lasting impact on the future of the Union in socio-economic terms...... middle of paper ......sion”: Memphis, Black Migration and white flight into the sanctuary.
