Most of Bosnia became vassal to Hungary as well after Croatiaentered personal union with the Hungarian kingdom in in 1102.

King Bela II of Hungary had claimed the Duchy of Rama, a region of northern Herzegovina, since 113.

His title since the Council at Ostrogon in 1138 had included "rex Ramae", likely referring to all of Bosnia.

Bosnia has found itself outside the control of various forces and, beginning with the reign of ban Borić in 1154, emerges as a semi-independent Banate under the sovereignty of the King of Hungary, an independent state under the rule of local bans.
