Question: Köprülüzade Numan Pasha, was a statesman who was the grand vizier of which empire, founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt (modern-day Bicelik Province) by the Oghuz Turkish tribal leader Osman?
Context: 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. Köprülüzade Fazıl Mustafa Pasha ("Köprülü Mustafa Pasha the Wise", also known as Gazi Fazıl Mustafa Köprülü (Albanian: Fazil Mustafa Kypriljoti ; 1637 – 19 August 1691, Slankamen) served as the Grand Vizier of the Ottoman Empire from 1689 to 1691, when the Empire was engaged in a war against the Holy League countries in the Great Turkish War.  He was a member of the Köprülü family of Albanian origin.  His father Köprülü Mehmed Pasha, his elder brother Köprülü Fazıl Ahmed Pasha, as well as his two brothers-in-law (Kara Mustafa Pasha and Abaza Siyavuş Pasha) were former grand viziers.  His epithet "Fazıl" means "wise" in Ottoman Turkish. Topal Recep Pasha ("Recep Pasha "Lame"; died 18 May 1632) was an Ottoman statesman from the Sanjak of Bosnia, as well as Damat ("bridegroom") to the House of Osman.  He served as the Grand Vizier of the Ottoman Empire from 10 February 1632 to 18 May 1632.  He was instrumental in lynching the former grand vizier, Hafız Ahmet Pasha.  When his brother-in-law Sultan Murad IV realized this, he had Recep Pasha executed on 18 May 1632. The Ottoman dynasty (Turkish: "Osmanlı Hanedanı" ) was made up of the members of the imperial House of Osman (Ottoman Turkish: خاندان آل عثمان‎ "Ḫānedān-ı Āl-ı ʿOsmān").  Also known as the Ottomans (Turkish: "Osmanlılar" ).  According to Ottoman tradition, the family originated from the Kayı tribe branch of the Oghuz Turks, under Osman I in northwestern Anatolia in the district of Bilecik Söğüt.  The Ottoman dynasty, named after Osman I, ruled the Ottoman Empire from c. 1299 to 1922. The Ottoman Empire (; Ottoman Turkish: دولت عليه عثمانیه‎‎ , "Devlet-i ʿAlīye-i ʿOsmānīye ", literally The Exalted Ottoman State; Modern Turkish: "Osmanlı İmparatorluğu " or "Osmanlı Devleti "; also historically known in Western Europe as the Turkish Empire, Ottoman Turkey or simply Turkey) was an empire founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt (modern-day Bicelik Province) by the Oghuz Turkish tribal leader Osman.  After 1354, the Ottomans crossed into Europe, and with the conquest of the Balkans, the Ottoman Beylik was transformed into a transcontinental empire.  The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror. 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 ("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. 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). Köprülüzade Numan Pasha (Albanian: "Numan Pashë Kypriljoti" ; 1670–1719) was an Ottoman statesman who was the grand vizier of the Ottoman Empire between June and August 1710.  He was a member of the influential Köprülü family, as well as a "damat" ("bridegroom") to the Ottoman dynasty after marrying an Ottoman princess. Ertuğrul (Ottoman Turkish: ارطغرل‎ , Ertuğrul Gazi, Erṭoġrıl; often with the title "Gazi") (died c. 1280) was the father of Osman I, the founder of the Ottoman Empire.  While his historicity is proven by coins minted by Osman I which identify Ertuğrul as the name of his father, nothing else is known for certain about his life or activities.  According to Ottoman tradition, he was the son of Suleyman Shah, leader of the Kayı tribe of Oghuz Turks, who fled from eastern Iran to Anatolia to escape the Mongol Conquests.  According to this legend, after the death of his father, Ertuğrul and his followers entered the service of the Seljuks of Rum, for which he was rewarded with dominion over the town of Söğüt on the frontier with the Byzantine Empire.  This set off the chain of events that would ultimately lead to the founding of the Ottoman Empire.  Like his son, Osman, and their descendants, Ertuğrul is often referred to as a "Ghazi", a heroic champion fighter for the cause of Islam.
