Canton 10

Canton 10 (Croatian: Herceg-Bosanska županija, lit. 'Herzeg-Bosnia County'), is one of the ten cantons of the Federation of Bosnia and Herzegovina, a political entity of Bosnia and Herzegovina. It is the largest canton by area and eighth by population. The local government seat is in Livno, while the assembly is in Tomislavgrad. It is divided into five municipalities: Bosansko Grahovo, Drvar, Glamoč, Kupres, Tomislavgrad and one city, Livno.

The canton was established in 1996, following the Washington Agreement of 1994, which ended the Croat-Bosniak War. The majority of the population is ethnically Croat, living in the southern part of the canton, while the second-largest Serbs live in the northern part.

During the Bosnian War, the Croatian Defence Council (HVO) controlled the southern parts of the canton, while other parts, mostly in the north, were controlled by the Serb Army of Republika Srpska until 1994 when they were re-taken by the HVO with the support from the Croatian Army. Per the Washington Agreement, the territories were incorporated into the Croat-Bosniak Federation of Bosnia and Herzegovina. From 1996 to 2005, only Croats and Bosniaks were considered to be constituent nations within the canton, but since 2005, the Serbs are included among the constituent nations as well and are mentioned as such before the less numerous Bosniaks.
