The Köprülü Grand Vizier refers to a prominent family of Ottoman statesmen who served as grand viziers during the 17th century. The most notable member, Köprülü Mehmed Pasha, held the position from 1656 to 1661 and is credited with significant military and administrative reforms that strengthened the Ottoman Empire. His leadership helped restore order and improve the empire's finances. The Köprülü era is marked by military successes, including campaigns against the Habsburg Monarchy and Venetian Republic. The family's influence continued with other grand viziers, such as Köprülü Ahmed Pasha, who furthered their legacy in Ottoman governance and military strategy.
