“...a formerly enslaved individual...”
I like how Smithsonian uses the now politically-correct phase instead of the more concise “a former slave”. I’m quite sure if you could go back in time and ask him, he’d say he used to be a slave, rather than ‘an enslaved individual’. And, of course, the same would be true of former slaves in the U.S.
That has become the politically-correct term for "slave"--"enslaved person." I guess that is supposed to remind us of their humanity, but I don't like the idea of using terms that were not current at the time (just as the Declaration of Independence does not call "the merciless Indian savages" "the merciless Native American savages").
I recently read an article several pages long about slaves, runaway slaves, and freedmen in a Southern town in the Civil War, which never once referred to them as slaves--always as "enslaved persons."
