I think the quiz title is a bit misleading - love the idea of these former empires etc as a quiz - but there are more 'empires' here than single countries. It would be good to see the quiz just about countries that have been broken up or absorbed into others, eg Yugoslavia, Czechoslovakia, Hong Kong!
The type-ins need to be cleaned up a lot.
* Didn't accept "Macedonian"
* Remove "Empire" as a requirement to type in
* Accept "Mongolian"
* Accept "Frankish," "Francia," and "Carolingian"
