For a time, these reforms led to real advances for African Americans in the south. When the north withdrew its army from the southern states, especially during the late 1870s, white southerners regained political power and began to deprive southern blacks of their new rights. Southern blacks were free, but the local laws denied them their rights. They had the right to vote, but the threat of violence made them afraid to use it. Southern states introduced "segregation" a system that required blacks and whites to use separate public facilities, from schools to drinking fountains. Not surprisingly, the black facilities were not as good as the white facilities. The races lived separately in the south for the next 100 years. In the 20th century, this would become a national issue.
一段时间，这些改革导致在南部的非洲裔美国人真正进步。当北部撤出其军队从南部的州，特别是在19世纪70年代末，白南部的人恢复政治权力，并开始剥夺了的南部的黑人的新权利。南部黑人是免费的，但当地的法律剥夺了他们自己的权利。他们有投票权，但以暴力相威胁使他们不敢使用它。南州推出“隔离”它是一个系统要求黑人和白人使用单独的公共设施，从学校到饮水机。毫不奇怪，黑人的设施没有白人的设施好。在南部这种种族分离持续未来100年。在20世纪，这将成为一个全国性的问题。
