Question

Which primary source document could help a historian understand why the US Civil War started?

Answer 1

The correct answer here would be the last option.

Charleston Mercury editorial published in 186. a year before the beginning of the US Civil War, would be and ideal item for an historian trying to understand the situation in the US at that time. Newspaper articles are considered one of the primary sources that are used to study history. They represent evidence and testimony of a time long passed. 

Answer 2

I think the correct answer from the choices listed above is the third option. The primary source document that could help a historian understand why the US Civil War started is a Charleston Mercury editorial published in 1860 because it contains factual accounts of the events during that time. Hope this answers the question.
