Köprülü Reforms

Timeline

1. 1656Topkapı Palace · ConstantinopleAged about eighty, Köprülü Mehmed Pasha set three conditions for taking office: full powers, non-interference by the sultan in daily governance, and that any accusation be presented face to face. Sultan Mehmed IV and the queen mother Turhan Sultan, pressed by internal and external crises, agreed to all. Köprülü's appointment marked the shift of the Ottoman central authority from palace factions to a strong grand vizier, opening nearly thirty years of family rule.
2. 1656–1658Constantinople and the empire's provinces · Ottoman EmpireIn the early days of his rule Köprülü swiftly executed corrupt officials, mutinous Janissary officers, disloyal provincial governors, and religious figures opposed to reform, with total executions estimated between several thousand and over ten thousand (sources vary significantly). The sipahi knight rebellion in Anatolia was also suppressed by force. This purge completely broke the political pattern of the past five years in which grand viziers were manipulated, establishing the reform government's strong authority at home and abroad.
3. 1656–1657Dardanelles and northern Aegean · Aegean SeaKöprülü oversaw the construction of new galleys, appointed a trusted confidant as naval commander, and personally went to the Dardanelles front to command. In 1657 the Ottoman fleet defeated the Venetian blockade fleet and promptly recovered Lemnos, Bozcaada, and Gökçeada, lifting the Dardanelles blockade and restoring Constantinople's Black Sea grain supply line. This was the Ottoman navy's most important strategic victory in nearly twenty years.
4. 1658–1660Transylvania and Wallachia · Principality of TransylvaniaTransylvanian prince Rákóczi II unilaterally joined the contest for the Polish throne, and Köprülü used this as grounds for a punitive expedition. In 1658–1659 Ottoman forces successively deposed and installed the rulers of Transylvania, Wallachia, and Moldavia, installing pro-Ottoman regimes. In 1660 the fortress of Várad was captured, and this strategic stronghold was incorporated into an imperial directly governed province, further strengthening Ottoman control over the Danube basin.
5. 1660–1661Constantinople · ConstantinopleIn his final years in office Köprülü enforced strict fiscal discipline, cutting court expenditures, auditing the land tax base, and trimming surplus military registrations, partially restoring the treasury from near-bankruptcy within a few years. Köprülü died in October 1661, and his son Fazıl Ahmed Pasha smoothly succeeded him as grand vizier; the smooth father-to-son transfer of power was itself the best proof of the reform's success, and the Köprülü Reforms entered their second phase.
