The slave shown in this photograph, who had been badly mistreated by his overseer, sat for this portrait in 1863 – during the American Civil War (1861–1865). In addition to political and economic measures, the anti-slavery movement exerted influence on the military conflict between the northern and southern states of the USA.
Overseer Artayou Carrier whipped me. I was two months in bed sore from the whipping. My master come after I was whipped; he discharged the overseer. The very words of poor Peter, taken as he sat for his picture.
