It’s Black History Month. And, I wrote about Freedom House (1315 Duke Street, Alexandria) a year ago. During its 33 years of operation, some 1 million slaves were sold or traded from this building. Interestingly, these actions occurred even when Alexandria was part of the District of Columbia- Alexandria rejoined the Commonwealth in 1847, after 58 years of Federal Control. (The slave house actually operated from 1828 to 1861; that operation ceased when the US government forcibly took control over the city of Alexandria at the start of the Civil War.)
