Input: Consider Input: Question: What was the capital of Bulgaria in 1902? Passage:In the spring of 1902, Bulgaria, an Ottoman vassal state which was interested in acquiring Macedonia, signed a military convention with Russia. Late in the fall, Russia, supported by the United Kingdom and France, proposed to the Ottomans political reforms for the Macedonian vilayets. On 8 December, the Ottoman sultan, Abdul Hamid II, signed a decree implementing most of the reforms. In February 1903, the new Russian foreign minister, Vladimir Lamsdorf, visited Vienna and signed the so-called "Vienna Program" on Macedonian reforms. The program was substantially the same as the Ottoman decree of December. The immediate provocation of a new agreement at Murzsteg was the IlindenPreobrazhenie Uprising that broke out on 2 August. With its quick suppression, the Vienna Program lay dead. In September Tsar Nicholas II of Russia visited the Emperor Francis Joseph of Austria-Hungary at the latter's castle in Murzsteg, Austria. The two rulers put their signatures to a new memorandum, substantially identical to the Vienna Program, which called for the appointment of one Russian and one Austro-Hungarian civil agent to oversee the reform of the administration, judiciary and local gendarmerie in the Macedonian vilayets. In all these institutions Christians were to take part. After Abdul Hamid accepted the proposal in November, Russia appointed one N. Demerik as its agent, and Austria chose one G. Muller. They began their work under Huseyin Hilmi Pasha, the Inspector-General of Macedonia, in early 1904. Under the Murzsteg program, each Great Power appointed an advisory official to the Ottoman official in charge of reforming the gendarmerie in each province. Austria-Hungary appointed an advisor to the sanjak of Uskup, Russia to the sanjak of Thessaloniki, France to the sanjak of Siroz and Britain to the sanjak of Drama.
