Köprülüdür. Amasya civârında Köprü kazâsından ve sipâhi meşâhirinden Köprülü Ömer Ağa’nın mahdûmudur. Bu da sipâhi iken İstanbul’da Yeniçeri ocağının ilgâsını müteâkib açılan Nizâm Ocağında süvâri mülâzımı oldu.¹³⁰
Ba’dehû terakkîyâta mazhar olarak 1247’de binbaşı, 1250’de kâim-makâm, 1253’de süvarî mîr-âlâyı ve 1256’da mîrlivâ olup Anadolu ordusu erkânından olduğu halde 1261’de vefât etdi. Köprülü Rahtuvân İsmâil Ağazâde sipâhiler kethüdâsı Ömer Ağa’nın mahdûmu olduğu anlaşıldı. [204]
He is from Köprü. He is the son of Ömer Ağa of Köprü, from the Köprü district near Amasya, one of the notable sipahis. While still a sipahi, he became a cavalry cadet in the Nizam Corps opened in Istanbul after the abolition of the Janissary Corps.
Afterward, rising through promotions, he became binbaşı in 1247 [1831-32], kaymakam in 1250 [1834-35], cavalry colonel in 1253 [1837-38] and mirliva in 1256 [1840-41]; while one of the leading figures of the Anatolian army he died in 1261 [1845]. It was learned that he is the son of Ömer Ağa, kethüda of the sipahis, who was the son of Rahtuvân İsmâil Ağa of Köprü.
The Janissary Corps was abolished by decree on 17 June 1826, and the same decree announced that a new army in the European manner, the Asâkir-i Mansûre-i Muhammediye, would be formed. According to its regulation the army was to number 12,000 men, divided into eight tertips of 1,500 each. What Hüsameddin calls the "Nizam Corps" is most likely this new army; this matching is an inference. According to the book's footnote, İsmâil appears in the Istanbul "Cavalry Register" in 1244 [1828-29] as Köprülüzâde İsmâil Ağa with the rank of mülâzım; this record agrees with the account that he took up service in the new army shortly after the corps was abolished.
According to the footnote, his father, Hâfız Ömer Ağa, kethüda of the sipahis, was the brother of Köprülü Hâfız Hasan Ağa, head of the sultan's musketeers; Hasan Ağa's son, İsmâil Efendi, müderris of the Sâniye-i Süleymaniye (entry 212 of the book), is therefore İsmâil Pasha's first cousin. No information was found in other sources about Köprülüzâde İsmâil Pasha's military career.
