1871, when France was crushed in the Franco-Prussian War. While Prussia and several other German states united into a powerful German Empire, Napoleon III was deposed in the formation of the French Third Republic. Napoleon had opposed Russia over the Eastern question in order to gain the support of Britain. But the new French Republic did not oppose Russian interference in the Ottoman Empire because that did not significantly threaten French interests. Encouraged by the decision of France, and supported by the German minister Otto, Fürst von Bismarck, Russia denounced the Black Sea clauses of the treaty agreed to in 1856. As Britain alone could not enforce the clauses, Russia once again established a fleet in the Black Sea. Great Eastern Crisis (1875–78) In 1875 the territory of Herzegovina rebelled against the Ottoman Sultan in the Province of Bosnia; soon after, Bulgaria rebelled as well. The Great Powers believed they should intervene to prevent a bloody war in the Balkans. The first to act were the members of the League of the Three Emperors (Germany, Austria-Hungary and Russia), whose common attitude toward the Eastern Question was embodied in the Andrassy Note of 30 December 1875 (named for the Hungarian diplomat Julius, Count Andrassy).

But the Herzegovinian leaders rejected the proposal, pointing out that the Sultan had already failed in his promises of reforms. Representatives of the Three Emperors met again in Berlin, where they approved the Berlin Memorandum (May 1876). To convince the Herzegovinians, the memorandum suggested that international representatives be allowed to oversee the institution of reforms in the rebelling provinces. But before the memorandum could be approved by the Porte, the Ottoman Empire was convulsed by internal strife, which led to the deposition of Sultan Abdul-Aziz (30 May 1876). The new Sultan, Murad V, was himself deposed three months later due to his mental instability, and Sultan Abdul Hamid II came to power (31 August 1876). In the meantime, the hardships of the Ottomans had increased; their treasury was empty, and they faced insurrections not
