The Kingdom of Hungary-Poland

Hungary stronk

I'm thinking about doing a series of maps of uber-countries like this.
If I follow through, that'll make this the first one. 
They'll all be historical countries that go above and beyond.

*-loose explanation time-*

1. Way back when, the Huns move in, take the same territory but grab Bohemia as well.

2. Later, he Kingdom of Hungary holds off the Ottomans,
    strengthens its position with a personal union with Poland (which it later annexes),
    and grabs some surrounding territories, including what remained of an incredibly battered Austria.

3. ???

4. Profit*
