The Herzegovina Uprising of 1875–77 (, ) was an uprising led by ethnic Serbs against the Ottoman Empire, firstly and predominantly in Herzegovina (hence its name), from where it spread into Bosnia. It is the most significant of the rebellions against Ottoman rule in Herzegovina. The uprising was precipitated by the harsh treatment under the beys and aghas of the Ottoman province (vilayet) of Bosnia — the reforms announced by the Turkish Sultan Abdülmecid I, involving new rights for Christian subjects, a new basis for army conscription, and an end to the much-hated system of tax-farming, were either resisted or ignored by the powerful Bosniak landowners. They frequently resorted to more repressive measures against their Christian subjects. The tax burden on Christian peasants constantly increased.
