The Bosnian uprising (also known as Great Bosnian Uprising) was a revolt of Bosnian ayans (landlords) against the Ottoman Empire. The casus belli were reforms implemented by the Sultan to abolish the ayan system. Despite winning several notable victories, the rebels were eventually defeated in a battle near Sarajevo in 1832. Internal discord contributed to the failure of the rebellion, because Gradaščević was not supported by much of the Herzegovinian nobility.
