When, under the Treaty of Berlin ( 1878 ), Bulgaria became an autonomous principality under the suzerainty of the Ottoman Empire, the Tsar recommended his nephew to the Bulgarians as a candidate for the newly-created throne, and the Grand National Assembly unanimously elected Prince Alexander as Prince of Bulgaria ( 29 April 1879 ).

Before proceeding to Bulgaria, Prince Alexander paid visits to the Tsar at Livadia, to the courts of the great powers and to the sultan ; a Russian warship then conveyed him to Varna, and after taking the oath to the new constitution at Turnovo ( 8 July 1879 ) he went to Sofia.

This arrangement, however, cost Alexander much of his popularity in Bulgaria, while discontent prevailed among a number of his officers, who considered themselves slighted in the distribution of rewards at the close of the campaign.
