Tropolje

Tropolje was a historical Croatian duchy, which was located on the borderland of Croatia, Bosnia and Zachlumia.

Its exact borders are disputed among historians.

Additionally, Dominik Mandić included Livanjsko Polje as well.

Karbić, agreeing with Draganović, said that a document from 1301 supports his conclusion and that the northern borders thus defined, fitted the borders of the Diocese of Duvno.

[2] The document from 1301, to which Karbić was referring, mentions the sons of Paul I Šubić of Bribir – Mladen, George and Paul, as "Duke of Tropolje, Livno and Cetina", who adopted the title on the verge of the 13th to 14th century after securing the territory of the eastern Adriatic hinterland.
