Ottoman Bulgaria in the context of "Liberation of Bulgaria"

The Russo-Turkish War (1877–1878) was a conflict between the Ottoman Empire and a coalition led by the Russian Empire which included Romania, Serbia, and Montenegro. Precipitating factors included the Russian goals of recovering territorial losses endured during the Crimean War of 1853–1856, re-establishing itself in the Black Sea and supporting the political movement attempting to free Balkan nations from the Ottoman Empire. In Romania the war is called the Russo-Romanian-Turkish War (1877–1878) or the Romanian War of Independence (1877–1878).

The Russian-led coalition won the war, pushing the Ottomans back all the way to the gates of Constantinople, leading to the intervention of the Western European great powers. As a result, Russia succeeded in claiming provinces in the Caucasus, namely Kars and Batum, and also annexed the Budjak region. The principalities of Romania, Serbia, and Montenegro, each of which had had de facto sovereignty for some years, formally proclaimed independence from the Ottoman Empire. After almost five centuries of Ottoman domination (1396–1878), Bulgaria emerged as an autonomous state with support and military intervention from Russia.

The Cretan Muslims or Cretan Turks (Greek: Τουρκοκρητικοί or Τουρκοκρήτες, Tourkokritikí or Tourkokrítes; Turkish: Giritli, Girit Türkleri, or Giritli Türkler; Arabic: أتراك كريت) were the Muslim inhabitants of the island of Crete. Their descendants settled principally in Turkey, the Dodecanese Islands under Italian administration (part of Greece since 1947), Syria (notably in the village of Al-Hamidiyah), Lebanon, Palestine, Libya, and Egypt, as well as in the larger Turkish diaspora.

Cretan Muslims were descendants of ethnic Greeks who had converted to Islam after the Ottoman conquest of Crete in the seventeenth century. They identified as Greek Muslims, and were referred to as "Turks" by some Christian Greeks due to their religion; not their ethnic background. Many Cretan Greeks had converted to Islam in the wake of the Ottoman conquest of Crete. This high rate of local conversions to Islam was similar to that in Bosnia-Herzegovina, Albania, parts of western Greek Macedonia (such as the Greek Muslim Vallaades), and Bulgaria; perhaps even a uniquely high rate of conversions rather than immigrants. The Greek Muslims of Crete continued to speak Cretan Greek. European travellers' accounts note that the "Turks" of Crete were mostly not of Turkic origin, but were Cretan converts from Orthodoxy.

Osman Nuri Pasha (Ottoman Turkish: عثمان نوری پاشا‎; 1832, Tokat, Ottoman Empire – 4 to 5 April 1900, Constantinople, Ottoman Empire), also known as Gazi Osman Pasha (Turkish: Gazi Osman Paşa), was an Ottoman Turkish field marshal. Being one of the most respected and decorated Ottoman pashas of all time, many songs have been written for him, and many places named after him. This is mainly because he held the Bulgarian town of Plevna for five months against superior Russo-Romanian forces in 1877 during the Russo-Turkish War, though the city eventually fell.
