Why would a researcher use a secondary source instead of a primary source when analyzing historical event

Because a primary resource would be an interview of someone in that event or their diary or something they wrote about that event. If you couldnt find anything, you would have to use the secondary source, a book or article written about that event but the author wasnt in it or there

Just think, why was it effective? -it appeled to critics because it was written well, that made it noticeable to the public including the white population-it was also recognizable to the african americans because it was about their heritage.-it was powerful just keep finding more points and elaborate on them. message me if you need more

It vendetta against him
