Mehmet was born in Osmancık, near Çorum. He was of Turkish origin. He travelled to North Africa, which was then Ottoman territory. He then came to Constantinople, the capital of the empire, where he found a job as a baltacı in the palace of the sultan which earned him the epithet Baltacı. He also worked as a secretary and muezzin and earned the nickname pakçemuezzin. Soon, he was promoted to be the chief stableman and then Grand Admiral in 1704. On 25 December 1704, he became the grand vizier.
There are no remarkable feats in his first term as Grand Vizier, and in 1706 he was dismissed. In just four years, he was appointed three times to various remote provinces, namely Erzurum, the islandChios, and Aleppo as a governor. On 18 August 1710, he began his second term as Grand Vizier.
Second term as Grand Vizier
His second term is quite well known. In 1709, during the Great Northern War, Charles XII of Sweden had been defeated by the Russians in the battle of Poltava and took refuge in Ottoman territory, with Peter I of Russia in pursuit. The Ottoman Empiredeclared war onRussia. Baltacı Mehmet was named the commander of the army. He was able to encircle the Russian army near the Pruth River, forcing Peter to sue for peace. The Treaty of Pruth stipulated the return of the fortress Azov, which had been annexed by Russia by the Treaty of Karlowitz, to the Ottomans; several Russian fortresses were to be demolished; Peter I promised not to interfere into the affairs of the Polish-Lithuanian Commonwealth and Charles XII was given a free passage to his country. Some contemporaries, such as Voltaire in his book Peter the Great, reported that Mehmet Pasha was involved in an affair with future-Empress Catherine I of Russia, then the consort of Peter. Surrounded by overwhelming numbers of Turkish troops, Catherine suggested before surrendering, that her jewels and those of the other women be used in an effort to bribe Baltacı Mehmet Pasha into allowing a retreat. Mehmet allowed the retreat, whether motivated by the bribe or considerations of trade and diplomacy. The story of Mehmet Pasha's relationship with Catherine I and his subsequent punishment by exile has been the subject of several works of literature in both Turkey and Russia, including the 1961 play Lütfen Dokunmayın by Turkish playwright Haldun Taner and the book Baltacı ile Katerina by Murat Sertoğlu.
Although the initial reaction of Sultan Ahmet III to the treaty was satisfactory, Baltacı Mehmet Pasha's political rivals, as well as Charles XII and Devlet II Giray, the vassal Crimean khan, were dissatisfied with the terms. He was accused of accepting the aforementioned bribe from Peter I of Russia and was dismissed from his post on 20 November 1711. Baltacı was exiled to the modern-day Greek islands of Lesbos and later Lemnos, where he died the next year in July 1712.
