too. By the grace of God, I have therefore ordered my brave army to join in the Holy War to free our brethren and to ensure a better future. In Old Serbia, my army will meet not only upon Christian Serbs, but also upon Muslim Serbs, who are equally dear to us, and in addition to them, upon Christian and Muslim Albanians with whom our people have shared joy and sorrow for thirteen centuries now. To all of them we bring freedom, brotherhood and equality." In a search for allies, Serbia negotiated a contract with Bulgaria. The agreement provided that, in the event of victory against the Ottomans, Bulgaria would receive all of Macedonia south of the Kriva Palanka-Ohrid line. Bulgaria accepted Serbian expansion to the north of the Shar Mountains (i.e., Kosovo). The intervening area was agreed to be "disputed"; it would be arbitrated by the Emperor of Russia in the event of a successful war against the Ottoman Empire. During the course of the war, it became apparent that the Albanians did not consider Serbia as a liberator, as suggested by King Peter I, nor did the Serbian forces observe his declaration of amity toward Albanians. Peter I led the Serbian army alongside marshals like Radomir Putnik, Stepa Stepanović, Božidar Janković and Petar Bojović. Serbia sent 230,000 soldiers (out of the population of just 2,912,000 people) with about 228 guns, grouped in 10 infantry divisions.

Serbian and Greek armies repulsed the Bulgarian offensive and counter-attacked, entering Bulgaria. With Bulgaria also having engaged in territorial disputes with Romania, this war provoked Romanian intervention against Bulgaria. The Ottoman Empire took advantage of the situation to regain some territories lost as a result of the previous war. When Romanian troops approached the Bulgarian capital, Sofia, Bulgaria asked for an armistice, resulting in the 1913 Treaty of Bucharest, in which Bulgaria had to cede portions of its First Balkan War gains to Serbia, Greece and Romania. The Second Balkan War left Serbia as the most militarily powerful state south of the Danube. Years of military investment financed by French loans had borne fruit. Central Vardar and the eastern half of the Sanjak of Novi Pazar were
