cond Balkan War broke out between the combatants in June 1913. A final peace was agreed at the Treaty of Bucharest on 10 August 1913.
In June 1913, a small Russian fleet, consisting of the gunboat Donets and the transport ships Tsar and Kherson, delivered the archbishop of Vologda, and a number of troops to Mount Athos to intervene in the theological controversy over imiaslavie (a Russian Orthodox movement).
The archbishop held talks with the imiaslavtsy and tried to make them change their beliefs voluntarily, but was unsuccessful. On 31 July 1913, the troops stormed the St. Panteleimon Monastery. Although the monks were not armed and did not actively resist, the troops showed very heavy-handed tactics. After the storming of St. Panteleimon Monastery, the monks from the Andreevsky Skete (Skiti Agiou Andrea) surrendered voluntarily. The military transport Kherson was converted into a prison ship and several imiaslavtsy monks were sent to Russia.
After a brief diplomatic conflict between Greece and Russia over sovereignty, the peninsula formally came under Greek sovereignty after World War I.

The self-governed region of the Holy Mountain, according to the Decree passed by the Holy Community on the 3rd October 1913 and according to the international treaties of London (1913), Bucharest (1913), Neuilly (1919), Sèvres (1920) and Lausanne (1923), is considered part of the Greek state. The Decree, "made in the presence of the Holy Icon of Axion Estin", stated that the Holy Community recognised the Kings of Greece as the lawful sovereigns and "successors on the Mountain" of the "Emperors who built" the monasteries and declared its territory as belonging to the then Kingdom of Greece.
