The Black Society for Salvation (Albanian: "Shoqëria e zezë për shpëtim" ) was a secret Albanian nationalist society established in 1909.
 Its main task was to organize uprisings in southern Albania and Macedonia struggling for the unification of the four Ottoman vilayets with the substantial Albanian population (Kosovo Vilayet, Scutari Vilayet, Monastir Vilayet and Janina Vilayet) into one autonomous political unit with its own government and parliament.
 The members of the society considered the armed rebellions as legitimate means for achieving their aims.
The Pashalik of Yanina or Janina (1788–1822) was a subdivision of the Ottoman Empire centred on the region of Epirus and had a high degree of autonomy in the early 19th century under Ali Pasha, although it was never recognized as such by the Ottoman empire.
 Its core was the Ioannina Eyalet, centred on the city of Ioannina in southern Epirus, but at its peak it comprised most of Albania and the western portions of Thessaly and Greek Macedonia in Northern Greece.
The Vilayet of Janina, Yanya or Ioannina (Ottoman Turkish: ولايت يانیه, Vilâyet-i Yanya‎ ) was a first-level administrative division (vilayet) of the Ottoman Empire, established in 1867.
 In the late 19th century it reportedly had an area of 18320 sqmi .
 It was created by merging Pashalik of Yanina and Pashalik of Berat with sanjaks of Janina, Berat, Ergiri, Preveze, Tırhala and Kesriye.
 Kesriye was later demoted to kaza and bounded to Monastir Vilayet and Tırhala was given to Greece in 1881.
The Ioannina Eyalet (Ottoman Turkish: ایالت یانیه; "Eyālet-i Yānyâ"‎ ) was an administrative unit of the Ottoman Empire located in the territory of present-day southern Albania, central and northern Greece.
 It was formed in 1670 and its administrative centre was Ioannina.
 In period 1788—1822 Ali Pasha, the sanjakbey of Trikala, seized control over Ioannina and after enlisting most of the local brigands under his own banner took advantage of a weak Ottoman government to gain control over the Ioannina Eyalet and most of Albania and continental Greece, transforming it into the semi-autonomous Pashalik of Yanina.
 After he was killed in 1822 the Ottoman Empire reestablished the Ioannina Eyalet which existed until establishment of the Janina Vilayet in 1867.
The Vilayet of Sivas (Ottoman Turkish: ولايت سيوس, Vilâyet-i Sivas‎ ;) was a first-level administrative division (vilayet) of the Ottoman Empire, and was one of the Six Armenian vilayets.
 The vilayet was bordered by Erzurum Vilayet to the east, Mamuretülaziz Vilayet to the south-east, the Trebizond Vilayet to the north and Ankara Vilayet to the west.
The Vilayet of Beirut was a first-level administrative division (vilayet) of the Ottoman Empire.
 It was established from the coastal areas of the Syria Vilayet in 1888 as a recognition of the new-found importance of its then-booming capital, Beirut, which had experienced remarkable growth in the previous years — by 1907, Beirut handled 11 percent of the Ottoman Empire's international trade.
 It stretched from just north of Jaffa to the port city of Latakia.
 It was bounded by the Syria Vilayet to the east, the Aleppo Vilayet to the north, the autonomous Mutasarrifate of Jerusalem to the south and the Mediterranean Sea to the west.
The Albanian Vilayet (Ottoman Turkish: ولايت ارناود‎ , "Vilâyet-i Arnavid") was a projected "vilayet" of the Ottoman Empire in the western Balkan Peninsula, which was to include the four Ottoman vilayets with substantial ethnic Albanian populations: Kosovo Vilayet, Scutari Vilayet, Manastir Vilayet and Janina Vilayet.
 At times it included the Salonica Vilayet too.
 The creation of the Vilayet was confirmed in September 1912, but negotiations were interrupted a month later in October with the beginning of the First Balkan War.
 Plans for an Albanian Vilayet were lost with the Partition of Albania.
Mit’hat Frashëri (also known by his nom de plume as Lumo Skëndo; March 25, 1880, Janina, Janina Vilayet, Ottoman Empire – October 3, 1949, Long Island, New York) was an Albanian diplomat, writer and politician.
 The son of Abdyl Frashëri, one of the most important activists of the Albanian National Awakening in 1908 he participated in the Congress of Monastir and in 1942 became the president of Balli Kombëtar (National Front) and finally fought as an ally of German forces and also his cousin became the prime minister of the puppet government of Albania.
 He is considered by many to be the father of Albanian Nationalism.
Rae Dalven (25 April 1904, Preveza, Janina Vilayet, Ottoman Empire – 30 July 1992, New York City) was a Romaniote author living in the United States of America since 1909.
 She is best known for her translations of Cavafy's works and for her books and plays about the Jews of Ioannina.
The Vilayet of Adana (Ottoman Turkish: ولايت اطنه, Vilâyet-i Adana‎ ; was a first-level administrative division (vilayet) of the Ottoman Empire in the south-east of Asia Minor, which encompassed the region of Cilicia.
 It was established in May 1869.
 Adana Vilayet bordered with Konya Vilayet (in west), Ankara Vilayet and Sivas Vilayet (in north), and Haleb Vilayet (in east and south).
 Adana Vilayet corresponds to the modern region of Çukurova in Turkey.
