What Was the Significance of the Federal Government in Helping or Hindering the Development of Civil Rights in America?

When examining the significance of federal action in the progress of African-American civil rights, it is important to acknowledge that this is not a narrative which climbed inexorably upward. As well as great instances of advancement, there were times when the lot of African-Americans deteriorated, or when progress was lessened, by the actions of the federal government. Similarly, it is also vital to remember that said government consists of three branches: Congress, the Presidency and the Supreme Court, and that this means talking of the federal government as a unitary authority presents a lack of both understanding and nuance.
