After the end of the Balkan Wars, the Kingdom of Serbia achieved the expansion towards the south, but there was a mixed reaction to the events, for the reason that the promises of lands gaining access to the Adriatic Sea were not fulfilled. Instead, Serbia received the territories of Vardar Macedonia that was intended to become part of the Kingdom of Bulgaria and the Serbian Army had to leave those coastal territories that would become part of the newly formed Principality of Albania. This event, together with the Austro-Hungarian Annexation of Bosnia, frustrated Serbian aspirations, since there was still a large number of Serbs remaining out of the Kingdom.
