The Eyalet of Bosnia[3] (Ottoman Turkish: ایالت بوسنه ,Eyālet-i Bōsnâ;[4][1] Turkish: Bosna Eyaleti;[4] Serbo-Croatian: Bosanski pašaluk), was an eyalet (administrative division, also known as a beylerbeylik) of the Ottoman Empire, mostly based on the territory of the present-day state of Bosnia and Herzegovina.

Prior to the Great Turkish War, it had also included most of Slavonia, Lika, and Dalmatia in present-day Croatia.

[6] The Ottoman wars in Europe continued throughout the period, and the province reached its territorial peak in 1683.

[8] In 1831, Bosnian kapudan Husein Gradaščević, after meeting in Tuzla with Bosnian aristocrats from 20 January to 5 February for preparations, finally occupied Travnik, demanding autonomy and the end of military reforms in Bosnia.

[1] 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.
