Final answer:
Exodusters were African Americans who moved out west to run from segregation and seek freedom after Reconstruction.
Step-by-step explanation:
The African Americans who moved out west to run from segregation were known as Exodusters. They were Southern black migrants who sought homes in the Great Plains and northern border states like Kansas and Indiana.
The Exodusters were hoping to find political, legal, and economic freedom that they were denied after Reconstruction. They faced opposition from Southern whites who feared the loss of their labor force and Northern whites who opposed black migration to their communities.
This migration westward led to a congressional investigation and significant efforts to stop the migration.
