I used to hate history books and I could not understand why. Now I finally get it. Any history book is only as good as the person that wrote it and his agenda. Really with many different views in the world you can pick what you want to write.
I think history should not be taught until college. 14-16 year olds are way too impressionable to think for themselves. They can easily get brainwashed.
Here is one little excerpt from a European history book I have written by Norman Davies, a British Oxford professor:
"Bolsheviks spurned St. Petersburg and moved the capital to Moscow".
Now the word "spurned" by itself insinuates a bad thing. But from the way I was taught in Russia the reason for moving the capital to Moscow was because St. Petersburg/Leningrad was a port city and was vulnerable to a Naval attack whereas Moscow was much deeper inland.
Be careful of history books! Some of them will find right and wrong according to their own agenda.
