He helped rebuild the power of the empire by rooting out corruption and reorganizing the Ottoman army. As he introduced these changes, Köprülü also expanded the borders of the empire, defeating the Cossacks, the Hungarians, and most impressively, the Venetians. Köprülü's effectiveness was matched by his reputation.He founded the city of Köprülü (now Veles, North Macedonia) in Rumelia.
