In autumn 1885, Eastern Rumelia united with Bulgaria through a coordinated political and military action.

Prince Alexander I supported the move, which was later recognized by the Ottoman Empire via the Tophane Agreement.

Background and detail

Background. Eastern Rumelia was an autonomous Ottoman province created in 1878. In spring 1885, the Bulgarian Secret Central Revolutionary Committee, formed by Zahari Stoyanov, began popularizing unification through press and demonstrations. Unionists prioritized Bulgarian unity over Macedonian revolution. Diplomatic hopes rose as British Prime Minister Gladstone appeared favorable to a potential union.

Execution. BSCRC representatives gathered rebels in Eastern Rumelian towns, directing them to Plovdiv under Major Danail Nikolaev. On 14 September, a riot in Panagyurishte was controlled. On 18 September, militia and unionists seized the governor's residence in Plovdiv. A temporary government immediately requested Prince Alexander I to accept the unification, which he confirmed via manifesto on 20 September.

Aftermath. Prince Alexander I had previously removed Russian advisors to assert independence. The removal of pro-Russian governor Gavril Krastevich enraged Tsar Alexander III. However, British Prime Minister Lord Salisbury accepted the unification as necessary to prevent Russian expansion. The de facto union was de jure recognized by the Ottoman Empire in the Tophane Agreement of April 1886.
