The Köprülü Era refers to a significant period in the history of the Ottoman Empire, spanning from the mid-17th century to the early 18th century. It is named after the Köprülü family, particularly Köprülü Mehmed Pasha, who served as the Grand Vizier. This era is marked by a series of reforms aimed at revitalizing the empire's administration and military, which had been declining. Under the leadership of the Köprülü family, the empire experienced military successes, including campaigns in Hungary and the Balkans. The reforms also focused on improving the financial system and curbing corruption within the government. This period is often seen as a time of recovery and consolidation for the Ottoman Empire.
