The Deligrad Event (Serbian: Делиградски догађај) was an attempt to elevate the Principality of Serbia to a kingdom during the Serbian–Ottoman Wars (1876–1878).
When the Great Powers agreed on ten days of ceasefire (3–13 September 1876), Imperial Russian Army general and Commander of the Armed Forces of the Principality of Serbia Mikhail Chernyayev, who opposed peace with the Ottomans, went on 4 September to General Kosta Protić and asked him to declare the proclamation of a kingdom to the Army.
It was compensation for the victims and the main profit of the war, which in his view, should continue after the truce for two months.
Chernyaev gave up on his threats, however, in order to save his reputation, the Prince's decision was not informed to the Morava–Timok Army.
On 16 September a Serbian offensive began and failed, after which Chernyaev left Serbia and the Great Powers took on the initiative in Constantinople to suspend the war.
