Only some history, and mostly general knowledge, particularly as pertains to most modern attitudes on various subjects. Geographically, I'm much better equipped. A friend of mine actually showed me a map of Earth a while back, drawn from his memory. Thankfully he has a didactic memory so I'm quite comfortable with its accuracy.

So, I know of England, I know where England is in your world, but my knowledge of the history and people of the country isn't exactly stellar.
