Accession Mehmed ascended to the throne in 1648 at the age of six, during a very volatile time for the
Ottoman dynasty. On 21 October 1649, Mehmed along with his brothers Suleiman and Ahmed were circumcised.
Kösem Sultan, Mehmed's grandmother and regent, was suspected of supporting the rebels and plotting to poison the sultan and replace him with his younger half-brother,
Suleiman. As a result, Mehmed agreed to sign his grandmother's death warrant in September 1651. The empire faced palace intrigues as well as uprisings in Anatolia, the defeat of the Ottoman navy by the Venetians outside the Dardanelles, and food shortages leading to riots in Constantinople. It was under these circumstances that Mehmed's mother granted
Köprülü Mehmed Pasha full executive powers as Grand Vizier. Köprülü took office on 14 September 1656. Mehmed IV presided over the
Köprülü era, an exceptionally stable period of Ottoman history. Mehmed is known as
Avcı, "the Hunter", as this outdoor exercise took up much of his time.
Wars by the Ottoman army Mehmed's reign is notable for a revival of Ottoman fortunes led by the
Grand Vizier Köprülü Mehmed and his son
Fazıl Ahmed. They regained the
Aegean islands from
Venice, and Crete, during the
Cretan War (1645–1669). They also fought successful campaigns against
Transylvania (1660) and
Poland (1670–1674). When Mehmed IV accepted the vassalage of
Petro Doroshenko, Ottoman rule extended into
Podolia and
Right-bank Ukraine. This event would lead the Ottomans into the
Russo-Turkish War (1676–1681). His next vizier, Köprülü Mehmed's adopted son
Merzifonlu Kara Mustafa, led campaigns against Russia, besieging
Chyhyryn in 1678 with 70,000 men. He next supported the 1683 Hungarian uprising of
Imre Thököly against
Austrian rule, marching a vast army through
Hungary and besieged
Vienna. At the
Battle of Vienna on the Kahlenberg Heights, the Ottomans suffered a catastrophic rout by Polish-Lithuanian forces famously led by King
John III Sobieski (1674–1696), and his allies, notably the Imperial army. In 1672 and 1673, the sultan, who embarked on two Polish-Lithuanian campaigns with
serdar-ı ekrem and Grand Vizier Fazıl Ahmed Pasha, and the acquisition of the Kamaniçi Castle, returned to Edirne after the signing of the Bucaş Treaty.
Fire of 1660 The fire of 4–5 July 1660 was the worst conflagration Constantinople had experienced to date. It started in Eminönü and spread to most of the historic peninsula, burning much of the city. Even the minarets of Suleiman I's mosque burned. Two-thirds of Istanbul was turned to ash in the conflagration, and as many as forty thousand people were killed. Thousands died in the
famine and
plague which followed the fire.
Great Turkish War of 1683 by
Gonzales Franciscus Casteels On 12 September 1683, the Austrians and their Polish-Lithuanian allies under King
John III Sobieski won the
Battle of Vienna with a devastating flank attack led by Sobieski's Polish cavalry. The Turks retreated into
Hungary; however, this was only the beginning of the
Great Turkish War, as the armies of the
Holy League began their successful campaign to push the Ottomans back to the Balkans.
Later life and death , 1686, by
Frans Geffels In May 1675, Mehmed IV's sons
Mustafa II and
Ahmed III were circumcised and his daughter Hatice Sultan was married. The empire celebrated it with Famous Edirne Festival to mark the occasion. Silahdar Findikli Mehmed Aga described Mehmed as a medium-sized, stocky, white-skinned, sun-burnt face, with a sparse beard, leaning forward from the waist up because he rode a lot. After the
Second Battle of Mohács in 1687, the Ottoman Empire fell into deep crisis. There was a mutiny among the Ottoman troops. The commander and Grand Vizier,
Sarı Süleyman Pasha, became frightened that he would be killed by his own troops and fled from his command, first to
Belgrade and then to Istanbul. When the news of the defeat and the mutiny arrived in Istanbul in early September,
Abaza Siyavuş Pasha was appointed as the commander and soon afterward as the Grand Vizier. However, before he could take over his command, the whole Ottoman Army had disintegrated and the Ottoman household troops (
Janissaries and
sipahis) started to return to their base in Istanbul under their own lower-rank officers. Sarı Suleiman Pasha was executed, and Sultan Mehmed IV appointed the commander of Istanbul Straits,
Köprülü Fazıl Mustafa Pasha, as the Grand Vizier's regent in Istanbul. Fazıl Mustafa made consultations with the leaders of the army that existed and the other leading Ottoman statesmen. After these, on 8 November 1687, it was decided to depose Sultan Mehmed IV and to enthrone his brother
Suleiman II as the new Sultan. Mehmed was deposed by the combined forces of Janissaries and
Sekbans commanded by
Osman Pasha. Mehmed was then imprisoned in
Topkapı Palace. However, he was permitted to leave the Palace from time to time, as he died in
Edirne Palace in 1693. He was buried in
Turhan Sultan's tomb, near his mother's mosque in
Constantinople. In 1691, a couple of years before his death, a plot was discovered in which the senior clerics of the empire planned to reinstate Mehmed on the throne in response to the ill health and imminent death of his successor, Suleiman II. ==Family==
