You might like to look at Skytrax; www.airlinequality.com which rates airlines with one to five stars. Most US based carriers get three stars, as does American. The site will also allow you to view passenger's comments bout their experiences. Again, many people only comment when things go wrong, so bear that in mind.
Reconstruction and Its Aftermath. The Emancipation Proclamation in 1863 freed African Americans in rebel states, and after the Civil War, the Thirteenth Amendment emancipated all U.S. slaves wherever they were. As a result, the mass of Southern blacks now faced the difficulty Northern blacks had confronted--that of a free people surrounded by many hostile whites.
By 1680, there were some 7,000 African slaves in the American colonies, a number that ballooned to 700,000 by 1790, according to some estimates. Congress outlawed the importation of slaves to the United States as of 1808, but the practice continued. The U.S. Civil War (1861-1865) resulted in the emancipation of approximately 4 million slaves.
