Slavery predates written history, and it continues into the present, but this category is about the system of slavery in 19th century America, which was a system wherein most of the slaves were black and were held by whites. Although slavery had been an issue, and a contentious one at that, since before the establishment of the United States, it hit its peak in the mid-19th century with the Dred Scott decision and the Fugitive Slave Act.
