The prince came of age in 1872 when he was eighteen, and he soon showed that the potential pleasures to be derived from his position were far more attractive to him than the fulfilment of its obvious duties. He found much to occupy him in Vienna and Paris and but little in Belgrade. At the same time the Serb people had lost, largely by its own faults, much of the respect and sympathy which it had acquired in Europe during Prince Michael’s reign. In 1875 a formidable anti-Turkish insurrection (the last of many) broke out amongst the Serbs of Bosnia and Hercegovina, and all the efforts of the Turks to quell it were unavailing. In June 1876 Prince Milan was forced by the pressure of public opinion to declare war on Turkey in support of the ‘unredeemed’ Serbs of Bosnia, and Serbia was joined by Montenegro. The country was, however, not materially prepared for war, the expected sympathetic risings in other parts of Turkey either did not take place or failed, and the Turks turned their whole army on to Serbia, with the result that in October the Serbs had to appeal to the Tsar for help and an armistice was arranged, which lasted till February 1877. During the winter a conference was held in Constantinople to devise means for alleviating the lot of the Christians in Turkey, and a peace was arranged between Turkey and Serbia whereby the status quo ante was restored. But after the conference the heart of Turkey was again hardened and the stipulations in favour of the Christians were not carried out.
In 1877 Russia declared war on Turkey (cf. chap. 10), and in the autumn of the same year Serbia joined in. This time the armies of Prince Milan were more successful, and conquered and occupied the whole of southern Serbia including the towns and districts of Nish, Pirot, Vranja, and Leskovac, Montenegro, which had not been included in the peace of the previous winter, but had been fighting desperately and continuously against the Turks ever since it had begun actively to help the Serb rebels of Hercegovina in 1875, had a series of successes, as a result of which it obtained possession of the important localities of Nik[’s]i[’c], Podgorica, Budua, Antivari, and Dulcigno, the last three on the shore of the Adriatic.
