The citizens of the empire in Constantinople believed that they were the citizens of Rome. Even after the city of Rome fell in the Fifth Century, contemporary Romans felt that the empire survived by moving East. In this way, Eastern and Western Rome were one in the same. It was only later that historians designated the title Byzantine Empire to the remaining remnants of the Roman Empire in the East.

The Reconstruction tried to generate opportunities to end the segregation between white Americans and African Americans in the Southern States by giving them job opportunities and voting rights so they could be elected into important political roles.
During the Reconstruction African Americans were able to enjoy family bonds and tried to make a way for former slaves buying land to cultivate. 
The problem was that the way Reconstruction was imposed created a brutal reaction in southern whites, that believed that they were stripped of their liberty, because of that many became committed to keeping blacks in a subservient position. With the election of President Johnson Reconstruction changed and the land was returned to white landowners which avoided land redistribution in the South.
The sharecropping system was a way of maintaining those ex-slaves and African Americans dependent on the landowners, it limited economic development and ensured that the South remained an agricultural location.
As we can see, the Reconstruction fell short of accomplishing its objectives because at the end it caused resentment in the Southern states, which backfired in the Black Codes and the creation of a series of white supremacy groups.
