Southeast Europe
This concept is based on the boundaries of the Balkan peninsula. The countries that have been described as being entirely within the region are: Albania, Kosovo, Bosnia and Herzegovina, Bulgaria, Macedonia and Montenegro.
First Balkan War
Montenegro was also considered as the smallest nation in the Balkan Peninsula, but in recent years before the war, with support from Russia, it had improved its military skills. Also, it was the only Balkan country never to be fully conquered by the Ottoman Empire. Due to Montenegro being the smallest member of the League, it didn't have much influence. Despite this, it was advantageous for Montenegro, because when the Ottoman Empire was trying to counter the actions of Serbia, Bulgaria and Greece, Montenegro had enough time for preparations which helped its successful military campaign.
