A little help with historians

[Historian]

EDIT: With a focus on the:
- French Revolution
- The Spanish Civil War
- The reformation

I would study the acts and works of those involved in those events. Specifically, I would study exactly what the French people wrote and did and what the Reformers wrote and did.

It is often quite different from a modern perspective. The "reformation" in particular was not laudable at all and it shed all of the things which are so valued today.
