Suleiman's successors with the
Safavids.
Sultan Suleiman I (r. 1520–1566) was the longest-reigning sultan in Ottoman history, but the last years of his reign were characterized by uncertainty over who would be his successor. Suleiman had three sons who could hope to succeed,
Mustafa,
Selim and
Bayezid. While the latter two were the children of Suleiman's wife
Hürrem Sultan, the first was the son of
Mahidevran Hatun. Mustafa may have felt that his half-brothers possessed an unfair advantage over him, and thus worked to secure the favor of the military. Perhaps suspecting that Mustafa planned to dethrone him just as
his own father had done to his
grandfather, Suleiman acted first and in 1553 ordered that Mustafa be executed. The death of Hurrem Sultan in 1558 triggered open conflict between the two remaining candidates, and Selim ultimately emerged victorious. Suleiman further strengthened his son's position by arranging a marriage between Selim's daughter and the influential
Sokollu Mehmed Pasha (
Grand Vizier 1565–1579). Suleiman died in 1566, while besieging the fortress of
Szigetvar in
Hungary, bringing Selim to the throne.
Selim II was a relatively inactive ruler who was content to allow the highly competent Sokollu Mehmed to run the empire on his behalf. Sokollu carried out a far-reaching foreign policy, dispatching armies to territories as distant as
Yemen in the south and
Astrakhan in the north. Most significant, however, was the conquest of
Venetian Cyprus in 1570 and subsequent Ottoman defeat in the
Battle of Lepanto, which paved the way for a Spanish-Ottoman truce in 1580 and continual détente in the
Mediterranean. This allowed the Ottomans to focus their expansion to the east against
Safavid Iran, where a long and devastating war was fought from 1578 to 1590, from which the Ottomans emerged with significant, if short-lived, conquests. Selim died in 1574 and was succeeded by his son
Murad III (r. 1574–95). This ruler, like his two successors
Mehmed III (r. 1595–1603) and
Ahmed I (r. 1603–1617), was highly influenced by the changing scene of palace politics. Most significant was the rise in importance of the
harem. Whereas Hurrem Sultan's power was based on her personal relationship with Suleiman, the imperial women of this period derived their power from the institutional structure of the harem, which placed immense power into the hands of the sultan's mother, the
Valide Sultan. This was directly related to the changes taking place in the system of succession, whereby princes no longer traveled to the provinces to take up governorships, but remained in the harem in Istanbul. From the time of Murad III onward, sultans no longer slept in the male segment of
Topkapı Palace, but resided in a new bedchamber within the harem. Due to the increasing role of imperial women in political life, this period is sometimes referred to as the
Sultanate of Women.
Crisis and adaptation in Istanbul, constructed in the reign of
Ahmed I (1603–1617). The Ottoman government at the turn of the century was presented with a severe military and economic crisis. War erupted with the
Austrian Habsburgs in 1593 just as Anatolia experienced the first of several
Celali Rebellions, in which rural bandit gangs grouped together under provincial warlords to wreak havoc on the countryside. In 1603 the Safavid Shah
Abbas I of Persia launched a
new war against the Ottomans, reversing all of the gains that had made in the previous decades. Thus the Ottomans found themselves fighting on three fronts at once, at a time when the economy was still recovering from the currency debasement of 1585. To overcome this challenge, they adopted an innovative strategy of co-opting the rebel forces into the structure of the empire. The Celali armies were manned by Anatolian bandits known as
sekban, former peasants who sought an alternate livelihood in the harsh economic climate of the turn of the century. When given the opportunity, these men were eager to earn pay and status by serving in the Ottoman army as mercenaries. By recruiting such men into the Ottoman army as musketeers their energies were redirected from banditry and put to use against the empire's external enemies. The Celali leaders, as well, were at times granted positions within the provincial administration in order to pacify them. This did not bring the anarchy in Anatolia to an end, but it did make it easier to manage. In 1609 the grand vizier
Kuyucu Murad Pasha traversed Anatolia with an army, clearing away the Celalis wherever he found them and bringing an end to the greater part of Celali activity. The wars with the Habsburgs and Safavids eventually devolved into stalemates. Mehmed III personally led the Ottoman army to victory over the Habsburgs in the
Battle of Keresztes in 1596, and the Ottomans went on to seize the Hungarian fortresses of
Eger and
Nagykanizsa, but ultimately neither side was able to achieve a decisive victory and the war was brought to an end in 1606 with the
Peace of Zsitvatorok. The war with the Safavids continued to drag on until 1618. The recruitment of
sekban as musketeers was part of a larger process of military and fiscal reform which was carried out during this period. The cavalry army which had been supported by the
Timar system during the sixteenth century was becoming obsolete as a result of the increasing importance of musket-wielding infantry, and the Ottomans sought to adapt to the changing times. The central army was greatly expanded, particularly the
Janissary corps, the empire's premier infantry force. The Janissaries began to experiment with new battlefield tactics, becoming one of the first armies in Europe to utilize
volley fire. To pay for the newly expanded army, the Ottomans expanded the practice of
tax farming, formerly used primarily in the Arab provinces. Taxation rights which were formerly given to cavalrymen were now sold to the highest bidder, a practice which was in use in much of Europe as well. Other taxes were also reformed, with the wartime tax known as
avarız becoming permanent and providing for 20% of the empire's annual revenue. These reforms greatly increased the revenue available to the central government and played a major role in the empire's continued strength throughout the century. To accommodate these changes, the bureaucracy was expanded and diversified, coming to play a much larger role in the empire's administration. , victim of the regicide of 1622.
Regicide and war Ahmed I's death in 1617 brought his brother to the throne as
Mustafa I, the first instance of a sultan succeeding through seniority. However, before long it became apparent that Mustafa was not mentally sound, and he was deposed the following year in favor of Sultan Ahmed's son
Osman II, then aged 13. Osman II was an exceptionally energetic ruler, and sought to restore the authority of the Ottoman sultanate over the other factional groups within the empire. This aroused the anger of both the
religious establishment as well as the
Janissaries and
Imperial Cavalry, and relations became particularly strained after the sultan's failed
Polish campaign, in which the army felt it had been mistreated. After their return to Istanbul, Osman II announced his desire to perform the
pilgrimage to Mecca; in fact this was a plan to recruit a new and more loyal army in Anatolia, out of the
bandit-mercenary forces which had taken part in the Celali Rebellions and the Ottomans' wars with the Habsburgs and Safavids. To prevent him from carrying out this plan, the imperial army launched a revolt on May 18, 1622, and two days later, with the approval of the
Şeyhülislâm, executed Osman. This event, the legally approved regicide of a reigning Ottoman monarch, cemented the empire's transformation from a patrimonial empire into one in which power was shared between various loci of authority. The regicide was followed by the revolt of
Abaza Mehmed Pasha, then governor of
Erzurum, who vowed to take revenge upon the sultan's killers and massacred the janissaries wherever he found them. Mustafa I, who had been enthroned for the second time, was soon deposed yet again and replaced by Ahmed I's son
Murad IV, still a child. Thus with a child on the throne, Istanbul under the control of a Janissary clique, and Abaza Mehmed running rampant in the east, the
Safavids saw another opportunity to attack and seized control of
Baghdad in January 1624, but were unable to advance to
Diyarbakır. In 1628 Abaza Mehmed's revolt was suppressed by the grand vizier
Gazi Hüsrev Pasha, whose dismissal from office in 1632 triggered a Janissary revolt. This event fueled Murad IV's desire to regain control over the state, and he henceforth began to exercise power in his own right. He carried out a reform of military land tenure in an effort to strengthen the army, encouraged peasant resettlement of abandoned fields, and enforced moral reform in Istanbul in conjunction with the religious movement of the
Kadizadelis. First achieving military success in 1635 with the conquest of
Yerevan, he was ultimately able to lead the empire to victory by reconquering Baghdad in 1638 and establishing a long-lasting peace with the Safavids the following year. Murad IV died in 1640, only 27 years old. He was succeeded by his brother
Ibrahim, the only remaining male member of the Ottoman dynasty. Like Mustafa I before him, Ibrahim was mentally unstable, and was initially content to leave the government in the hands of Murad IV's last grand vizier,
Kemankeş Mustafa Pasha. This lasted only until 1644, when Ibrahim had him executed and replaced by a rival. The following year
war between the Ottoman Empire and Venice was sparked by an incident in which
Maltese pirates docked at
Venetian Crete after attacking an Ottoman ship carrying pilgrims, including the
Chief Black Eunuch, to Mecca. The Ottomans quickly overran most of Crete, but were unable to evict the Venetians from the fortress of
Heraklion. At sea, the Venetians managed to achieve the upper hand and blockade the
Dardanelles, strangling Istanbul's trade and food supply. The subsequent disorder in the capital prompted Ibrahim's deposition in 1648, which was sanctioned by the Janissaries, the
şeyhülislâm, and even
Kösem Sultan, his mother. Ibrahim's replacement was his six-year-old son, who was enthroned as
Mehmed IV. The new government in Istanbul thus consisted of the young ruler's grandmother and regent Kösem Sultan and her allies in the Janissary Corps, one of whom was made grand vizier. Despite continued unrest both in Istanbul and the provinces, the blockade of the Dardanelles was successfully broken the following year. Kösem's position was nevertheless under threat from Mehmed IV's mother
Turhan Sultan. Upon learning of a plot by Kösem to poison Mehmed IV, Turhan's faction leapt into action and assassinated her in 1651. Turhan Sultan was henceforth in a secure position of power, but was unable to find an effective grand vizier, leaving the empire without a coherent policy with regard to the war with Venice. The result was
another revolt of the imperial troops in March 1656, which demanded the lives of several government officials, blamed for neglecting to properly pay the troops who had been struggling to conquer Crete for so long.
Köprülü era (1656–1661) restored stability to the empire after the disorder of the previous decade. In 1656 the Venetians seized control over the islands of
Lemnos and
Tenedos, and established another blockade of the Dardanelles. This action led to panic in Istanbul and prompted a renewed political crisis. In need of a change of policy, Turhan Hatice appointed the highly experienced
Köprülü Mehmed Pasha as grand vizier, who immediately set forth on a drastic process of reform. This involved the dismissal or execution of all officials deemed corrupt, and their replacement with men loyal to the vizier. While wintering in
Edirne after leading a successful campaign to reconquer the islands, Köprülü extended his purge to the
imperial cavalry, executing thousands of soldiers who showed any sign of disloyalty. This move prompted a serious reaction, and as Köprülü led the army in a campaign against
Transylvania, many of the empire's eastern governors first refused to join him, then launched an open revolt under the leadership of
Abaza Hasan Pasha, demanding from the sultan that Köprülü be executed. Mehmed IV, now no longer a minor, chose to side with his vizier and dispatched an army to defeat the rebels. Despite initial rebel victories, the revolt was suddenly brought to an end in February 1659 with the assassination of Abaza Hasan. Köprülü Mehmed died in 1661, leaving the empire in a much better military and financial position than he had found it. He was succeeded in office by his son
Köprülü Fazıl Ahmed Pasha (1661–1676), the first time in history that a grand vizier passed on the office to his son. Fazıl Ahmed was himself succeeded by his adopted brother
Merzifonlu Kara Mustafa Pasha (1676–1683), and it is due to this unbroken control of the
Köprülü family over the office of grand vizier that this period is referred to as the Köprülü era. Köprülü Mehmed's two successors were highly competent administrators, and the empire enjoyed a remarkable degree of stability under their tutelage. Mehmed IV was content to allow them to manage the political affairs of the empire, but was nevertheless not an inactive ruler. He played a major role in imperial symbolism and legitimation, traveling with the army on campaign before handing supreme command over to the grand vizier. Thus while not directly leading the army, he still participated in the imperial campaigns, for which he was referred to as
gazi, or "holy warrior," by contemporaries. Under the Köprülüs the empire revived its expansion into Europe, conquering territory from the Habsburgs, Poland–Lithuania, and Russia, as well as bringing the war with Venice to an end with the conquest of
Heraklion in 1669. The push for territorial expansion under the Köprülüs reached its apex in 1683 with the
Siege of Vienna, which ended in Ottoman defeat. The defeat at Vienna ushered in a major political shift in the empire. As punishment for his failure, Mehmed IV ordered that Merzifonlu Kara Mustafa be executed, bringing an end to the undisputed Köprülü hold over the empire. The result was a period of political confusion at a time when the Ottoman Empire's European enemies were rallying together. In 1684 the Habsburgs, Poland–Lithuania, Venice, and the Papacy forged an alliance known as the
Holy League to oppose the Ottomans, launching a period of warfare which would last for sixteen years.
War of the Holy League conquer
Buda in 1686. . Conflict on multiple fronts placed great strain on the Ottoman ability to wage war. The empire was attacked simultaneously in Hungary, Podolia, and the Mediterranean region, while after 1686 their
Crimean vassals, who under normal circumstances supported the Ottoman army with tens of thousands of cavalry, were continually distracted by the need to fend off
Russian invasion. Istanbul's food supply was again threatened by Venetian naval activity in the Aegean, contributing to instability in the capital. In Hungary, the Habsburgs first reconquered
Nové Zámky in 1684, before moving on to Buda. Despite
resisting a siege in 1684, it was unable to hold out against a
second two years later, and capitulated to the Habsburgs, leading to much of the country falling under Habsburg control. The Ottomans were able to rescue
Osijek from capture, but were defeated in the
Second Battle of Mohács in 1687. The army subsequently mutinied and marched on Istanbul, deposing Mehmed IV in favor of his brother
Suleiman II. In the chaos the Habsburgs were able to make rapid inroads into Ottoman territory, seizing strongholds such as
Eger and
Belgrade, reaching as far south as
Niš. However, in 1689 the tide turned back in the Ottomans' favor. In 1688
Louis XIV of France had launched the
Nine Years' War, distracting Habsburg attention from the Ottoman front.
Köprülü Fazıl Mustafa Pasha, a younger son of Köprülü Mehmed, was appointed grand vizier and led the army to successfully recover both Niš and
Belgrade. What followed was a long period of stalemate, with the Habsburgs having lost their bridgehead south of the
Danube and the Ottomans unable to achieve any lasting success north of it. The Habsburgs concerned themselves with the conquest of the
Principality of Transylvania, an Ottoman vassal state, the loss of which the Ottomans were forced to accept after the disastrous defeat of an army personally led by Sultan
Mustafa II in the 1697
Battle of Zenta. This defeat prompted the Ottomans to sue for peace. While territorial losses to the Habsburgs have at times been cited as evidence of military weakness, more recently historians have challenged this notion, arguing that Ottoman defeats were primarily a result of the sheer size of the coalition arrayed against them, and the logistical burden of fighting a war on multiple fronts. To this may be added political instability, for the empire's greatest losses took place from 1684 to 1688, when its political leadership was paralyzed first by the execution of Kara Mustafa Pasha and then the deposition of Mehmed IV. Subsequently, the Ottomans were able to stabilize their position and reverse Habsburg gains south of the Danube. The pressure of sustained warfare had prompted the Ottomans to carry out extensive fiscal reform. The sale of tobacco was legalized and taxed, previously tax-immune
waqf finances were reformed, and the
janissary payrolls were examined and updated. Most significantly, in 1691 the standard unit of
cizye assessment was shifted from the household to the individual, and in 1695 the sale of life-term
tax farms known as
malikâne was implemented, vastly increasing the empire's revenue. These measures enabled the Ottoman Empire to maintain fiscal solvency during the war, and to enjoy significant budget surpluses by the beginning of the eighteenth century. The war was brought to an end in 1699 with the
Treaty of Karlowitz. On the general principle of
uti possidetis, the Ottomans agreed to permanently cede all of
Hungary and
Transylvania to the
Habsburgs, with the exception of the
Banat region.
Morea was annexed by Venice, while
Podolia was returned to
Poland–Lithuania. Karlowitz was highly significant for both Ottoman and Eastern European history in general, for it marked the definitive end of Ottoman imperial expansion. After a final disastrous attempt to recover Hungary in the
Austro-Turkish War (1716–1718) Ottoman foreign policy in Europe during the subsequent eighteenth century was generally peaceful and defensive, focused on the maintenance of a secure network of fortresses along the Danube frontier. Sultan Mustafa II was overthrown in the 1703
Edirne incident, bringing an end to the rule of the final Ottoman warrior-sultan, cementing the empire's transformation into a bureaucratic empire. ==See also==
