What is one example of a primary source?

In the context of history, primary sources are documents/accounts that were written by people who actually experienced the event. An example could be a letter written by a soldier in WWI or Anne Frank's Diary.

Secondary sources, on the other hand, are written by people who learned about these events from someone else (meaning they did not actively participate or experience them). These would be your historians or newspaper journalists.
