Your mission, should you choose to accept it, is to make Estonia into a European power on the level of OTL Italy or Japan.
No POD limits, because you'll have to really fire up the wayback machine for this, I suspect. It doesn't even have to remain powerful in TTL's 2012, and it certainly doesn't have to be limited to the borders of OTL Estonia, but it has to have been a regional power at some period in its history and remain majority culturally Estonian.
Any takers?
