Netherlands!
We have very poor knowledge of our own history (no fellow dutchies, we were not the first republic), because most of us believe it to be realy boring.
Nothing could be less true! Beside being bullied by way bigger countries, we took on silly surnames just to piss off Napoleon, had the only supercorporation in history, sided with the Japanese to kick out the Catholics to aquire exclusive trade rights that lasted for centuries, sailed up the Thames and burned down every English ship in the harbor. Got bullied into trading New Amsterdam for Suriname (good deal in the end...), and best of all, were the first Europeans to import coffee on a large scale. Coffeeee~
Stuff did get considerably less good just before the start 19th century due to collapse of the east india company, failure to innovate, political instability (stupid monarchs...), and Napoleon finaly coming to finish off the republic.
Still its hardly boring. Maybe its just that nationalism never became very big here that we know so little about ourselves.
