An odd shaped country with lots of history and natural beauty (think Game of Thrones). Croatia used to include Bosnia. Through centuries of conflict with Hungary and the Ottomans, there was a division. The boundary largely resulted in the mountainous Bosnia serving as a defensive border for the Turks and the coastal areas being ruled by the Austro -Hungarians.
