Sanjaks[note 1] (/ˈsænæk/;[2] Ottoman Turkish: سنجاق; Modern Turkish: Sancak, pronounced [sanˈdʒak]) were administrative divisions of the Ottoman Empire. Sanjak, and the variant spellings sandjak, sanjaq and sinjaq, are English or French transliterations of the Turkish word sancak, meaning "district", "banner" or "flag".[3] Sanjaks were also called by the Arabic word for banner or flag: لواء liwa (Liwā or Liwā’).

The Vilayets and Sanjaks of the Ottoman Empire around 1317 Hijri, 1899 Gregorian

Ottoman provinces (eyalets, later vilayets) were divided into sanjaks (also called livas) governed by sanjakbeys (also called Mutesarriff) and were further subdivided into timars (fiefs held by timariots), kadiluks (the area of responsibility of a judge, or Kadı)[4] and zeamets (also ziam; larger timars).

The unofficial, geo-political region of Sandžak in Serbia and Montenegro derives its name from the former Ottoman Sanjak of Novi Pazar.
