The Eyalet of Herzegovina (Ottoman Turkish: ایالت هرسك; Eyālet-i Hersek,[1] Serbo-Croatian: Hercegovački pašaluk) was an administrative division (eyalet) of the Ottoman Empire from 1833 to 1851.

In 1831, Bosnian kapudan Husein Gradaščević occupied Travnik, demanding autonomy and the end of military reforms in Bosnia.

[2] Ultimately, exploiting the rivalries between beys and kapudans, the grand vizier succeeded in detaching the Herzegovinian forces, led by Ali-paša Rizvanbegović, from Gradaščević’s.

[2] This new entity lasted only for 18 years, that is, for the rest of Rizvanbegović's life: he was executed when the Porte discovered he was secretly building an independent power base.

The Pashaluk of Herzegovina was formed from following kazas:[citation needed] Prijepolje, Pljevlja with Kolašin and Šaranci with Drobnjak, Čajniče, Nevesinje, Nikšić, Ljubinje-Trebinje, Stolac, Počitelj, Blagaj, Mostar, Duvno and half of the county of Konjic which is on southern side of Neretva.
