What conclusions can you draw about the writing of the history of a country or an important event?

Question

My teacher just gave it in a handout like that, no specifications.

Answer 1

It is judged by the side who wrote it. No history is completely unbiased unless it is written by an uninvolved party. And the history of a war or conflict is almost always written by the winners of that war or conflict so the recorded history of the event will be biased in their favor.

Answer 2

The winners write the history books

Answer 3

You can usually conclude that whoever wrote it is going to give an account biased to their side.
