history and Americans

I've had a fair number of replies to my question about what periods of history people were taught about at school, but only one from an American. As her reply covered a surprisingly wide-ranging number of countries and periods, I'd like
to know if this was typical or unusual.

Could any other Americans reading this please give me a feel for the history they were taught at school. I'd hate to approximate a country from a single example.

Interestingly enough, I'm also finding age banding on the replies. The history we learnt partly depends on how old we are as well as where we come from. I think I may be able to work that rather neatly into my theory.
