Croatian Republic of Herzeg-Bosnia
In late July 1993 the Owen-Stoltenberg Plan was proposed by U.N. mediators Thorvald Stoltenberg and David Owen that would organize Bosnia and Herzegovina into a union of three ethnic republics. Serbs would receive 53 percent of territory, Bosniaks would receive 30 percent, and Croats 17 percent. The Croats accepted the proposal, although they had some objections regarding the proposed borders. The Serbs also accepted the proposal, while the Bosniak side rejected the plan, demanding territories in eastern and western Bosnia from the Serbs and access to the Adriatic Sea from the Croats. On 28 August, in accordance with the Owen-Stoltenberg peace proposal, the Croatian Republic of Herzeg-Bosnia was proclaimed in Grude as a "republic of the Croats in Bosnia and Herzegovina". However, it was not recognised by the Bosnian government.
