Context paragraphs:
Alaeddin Pasha (vizier): Alaeddin Pasha was the first Ottoman grand vizier.  His father's name was Kemalettin, and thus he was usually called "Hacı Kemalettin oğlu Alaeddin Pasha" or "Alaeddin bin Hacı Kemalletin, "meaning "son of Hacı Kemalettin's."  He was probably from the town of Cendere, from where the famous Çandarlı family also originated.  He was a fakih (expert in Islamic law).  He was appointed as the vizier during the last years of Osman I's reign (probably in 1320).  He continued during Orhan's Bey's reign.  Since there was only one vizier in the divan during the early years of the Ottoman beylik, his title was not actually grand vizier, but his post was equivalent to the post of the later grand viziers.  Because of this, he is known as the first grand vizier of the Ottoman Empire.

Kör Yusuf Ziyaüddin Pasha: Kör Yusuf Ziyaüddin Pasha ("Yusuf Ziyaüddin Pasha the Blind"), also known as Yusuf Ziya Pasha (died 1819), was an Ottoman statesman who twice served as the Grand Vizier of the Ottoman Empire in 1798–1805 and 1809–1811.  Before, between and after his terms as grand vizier, he served numerous posts as governor of various provinces and districts throughout the empire.  As grand vizier, he commanded the Ottoman ground forces against the French Army in the Ottoman reconquest of Egypt and later served as a commander in the Ottoman wars with the Russia Empire.

Mehmed Selim Pasha: Mehmed Selim Pasha or Mehmed Selim Sırrı Pasha (1771 Bender, Moldova – 1831 Damascus, Ottoman Empire, nickname: "Benderli") was an Ottoman statesman.  He was Grand Vizier of the Ottoman Empire.  He ruled from 14 September 1824 to 24 October 1828 as Grand Vizier of sultan Mahmud II and failed in the fight against the Greek War of Independence.  The Auspicious Incident ("Vaka-i Hayriye"), the Battle of Navarino (1827), happened during his period in office.  In 1828-30 he became Wali (governor) of Rumelia Province and 1830-31 Wali of Damascus (Syria).  When the citizens of Damascus and the local garrison of Jannisaries rose in revolt against him, Selim Pasha sought refuge into the Citadel of Damascus.  After a siege lasting 40 days he was promised safe passage but murdered before he could leave the city.

Osman Fazli: Osman Fazli (Turkish: Atpazarı Osman Fazlı-ilahi or Kutb Osman Fazlı), was a Jelveti Sufi spiritual guide in 17th-century Ottoman Empire.  He spent c.25 years teaching and preaching, and became head Sheikh of the order in Istanbul and led the studies, conversation, meditation, and dhikr.  But when he was about 48 it was revealed to him that the Ottoman Empire would fall into ruin, and, although he was of reclusive temperament, felt the only way to care for its population was to be at the Sultan's court.  There he was outspoken against many of the Grand Vizier's plans: that they would bring disaster and misfortune, and he was proven right.  He spent some years at court but when he declared one Grand Vizier's plan as against the sharia and distorting the Quran, the only way the Vizier could silence him was with exile.  Osman Fazli went into retreat but emerged with a different course of action: he was leading a band of Sufis towards the battlefront when he was arrested and exiled for good.  Osman Fazli exemplifies the Jelveti way: that following union with Allah he returns and acts in the world.  He is "hushyar" (awake).

Hadım Sinan Pasha: Hadım Sinan Pasha (Ottoman Turkish: خادم سنان پاشا, Modern Turkish: Hadım Sinan Paşa, "Sinan Pasha the Eunuch"; Bosnian: "Sinan-paša Borovinić" ; 1459 – 22 January 1517) was Grand Vizier of the Ottoman Empire from 1516 to 1517.  He was of Serb decent.

Zurnazen Mustafa Pasha: Zurnazen Mustafa Pasha was an Ottoman statesman of Albanian origin.  He was Grand Vizier of the Ottoman Empire for 4 hours on March 5, 1656.  He is sometimes excluded from the lists of Ottoman Grand Viziers.  He was promoted from the in-attorney title to the rank of full grand vizier due to the influence he exerted on the sultan for Gazi Hüseyin Pasha's dismissal from the office.  His appointment caused an uprising in Istanbul, and he was exiled after having only held the seal for four hours.

Semiz Ali Pasha: Semiz Ali Pasha (Bosnian: "Semiz Ali-Paša Pračić" ) was an Ottoman statesman from the Sanjak of Bosnia who served as Grand Vizier of the Ottoman Empire from 1561 to 1565.  He was the beylerbey (governor) of Egypt Eyalet from 1549 to 1553.  Semiz Ali Pasha was born in Prača in Bosnia (thus his secondary epithet), and replaced Rüstem Pasha as a Grand Vizier.  After palace schooling, he discharged high-level functions along the Ottoman Empire.

Eunuch: The term eunuch ( ; ) generally refers to a man who has been castrated, typically early enough in his life for this change to have major hormonal consequences.  In Latin, the words "eunuchus", "spado" (Greek: σπάδων "spadon"), and "castratus" were used to denote eunuchs.

Austro–Turkish War (1716–18): The Austro–Turkish War was fought between Austria and the Ottoman Empire.  The Treaty of Karlowitz (1699) was not an acceptable long-standing agreement for the Ottoman Empire.  Twelve years after Karlowitz, the Turks began the long prospect of taking revenge for their defeat at the Battle of Vienna in 1683.  First, the Turkish Grand Vizier Baltacı Mehmet's army defeated Peter the Great's Russian Army in the Russo–Turkish War (1710–1711).  Thereafter, in the Turkish–Venetian War (1714–1718), the new Grand Vizier Damat Ali re-conquered Morea from the Venetians in 1715.  As a reaction, Austria, as the guarantor of the Treaty of Karlowitz, threatened the Ottoman Empire, but in response the Ottoman Empire declared war against Austria.
