Second Balkan War
The last day of negotiations was 8 August. On 10 August Bulgaria, Greece, Montenegro, Romania and Serbia signed the Treaty of Bucharest and divided Macedonia in three: the largest part, Vardar Macedonia, went to Serbia; the smallest part, Pirin Macedonia, to Bulgaria; and the coastal part, Aegean Macedonia, to Greece. Bulgaria thus enlarged its territory by 16 percent compared to what it was before the First Balkan War, and increased its population from 4.3 to 4.7 million people. Romania enlarged her territory by 5 percent and Montenegro by 62 percent. Greece increased her population from 2.7 to 4.4 million and her territory by 68 percent. Serbia almost doubled her territory enlarging her population from 2.9 to 4.5 million.
