Mehmed IV (Turkish: IV. Mehmed or Mehmed Kıbrıs; Arabic: محمد الرابع; January 2, 1642 – January 6, 1693) was the Sultan of the Ottoman Empire from 1648 to 1687. His reign, which began when he was just six years old, was marked by significant military campaigns, including the Ottoman siege of Vienna in 1683, a pivotal moment in European history. Mehmed IV is often remembered for his role in expanding Ottoman influence, particularly in the Balkans and the Caucasus. The translation of his name to Hebrew is מהמט הרביעי. His reign saw both successes and challenges, including internal strife and the gradual decline of Ottoman military dominance in Europe. Mehmed IV's rule was also notable for the political influence of his mother, Kösem Sultan, and his grandmother, Kaffa Hatun, during his minority.
