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.
On September 22 1862, Abraham Lincoln issued his preliminary Emancipation Proclamation, in which he declared that as of January 1, 1863, all slaves in states in rebellion against the Union shall be then, thenceforward, and forever free..
As a correction, the Emancipation Proclamation, enacted by Lincoln in 1863, only freed the slaves in those states that were rebelling. Because the Union only controlled some small portions of the south at the time, only a small number of slaves were immediately freed. Slavery everywhere in the US wasn't abolished until the ratification of the 13th amendment in 1865, and there were still some slaves in the northern states who weren't freed until then.
