Here’s Professor Susanna Lee of NC State giving a lecture on changes to citizenship during Reconstruction.
The video’s description reads, “Professor Susanna Lee talked about the changing perception of who qualified for citizenship in post-Civil War America. She spoke about the legislation passed during this era and the debate about whether citizenship and voting privileges should be tied to loyalty to the Union, race, or gender. This class was from a course called ‘Introduction to Civil War and Reconstruction.’ ”
This lecture is filled with great information.
