Кёпрюлю
The Köprülü era () (c. 1656–1703) was a period in which the Ottoman Empire's politics were frequently dominated by a series of grand viziers from the Köprülü family. The Köprülü era is sometimes more narrowly defined as the period from 1656-1683, as it was during those years that members of the family held the office of grand vizier uninterruptedly, while for the remainder of the period they occupied it only sporadically. The Köprülüs were generally skilled administrators, and are credited with reviving the empire's fortunes after a period of military defeat and economic instability. Numerous reforms were instituted under their rule, which enabled the empire to resolve its budget crisis and stamp out factional conflict in the empire.
