The area of northern Herzegovina, which is considered as the municipal area of Prozor, Jablanica, and Konjic during the Homeland War in Bosnia and Herzegovina, was an area where severe war conflicts were fought between the Croat and Muslim sides. These conflicts developed their introductory predisposition back in 1992, at a time when the general emphasis of interethnic relations in the area was focused on resisting the actions of the Yugoslav People Army (YPA) and domicile Serb forces from Bosnia and Herzegovina. Different views, misunderstandings, and the impossibility of reaching of local political agreement and fulfilling the previously assumed joint defense obligations towardsthe Serbian side, led in October 1992 to the first open conflict between members of local Croatian and Muslim military organizations of the Croatian Defense Council (HVO) and the Army of Republic Bosna and Herzegovina (ABiH) in Prozor. The conflict in question, in which the local Croatian side in Prozor managed to push the Muslima ABiH out of the town of Prozor by military means, had an impact on the existing Croat-Muslim relations in the neighboring municipalities of Jablanica and Konjic. In the area of these ethnically heterogeneous municipalities, as in Prozor, existed similar inter-ethnic problems and relations between the ABiH and the HVO, which were caused by different political stands in the matter of the regulation of part of the area under Croat and Muslim control. Despite such problems, in the area of those two municipalities during 1992 it never came to the open conflict, such as the one in Prozor. Months of negotiations between local Croat and Muslim representatives to lower the tensions that occurred in late 1992 and in the first months of 1993 at the end were not accepted by the Muslim side. Shortly after, Muslim political leadership initiated the illegal political dismissal of their own political structures in Konjic and Jablanica, in the first half of April 1993 Muslim side planned and launched an open attack on the Croatian population in Konjic and Jablanica. In this way, started a series of severe open conflicts between the ABiH and the HVO, which lasted until the end of 1993. Attacks by ABiH on the HVO units were accompanied by major casualties, as well as mass persecution and imprisonment of the Croat population. By the end of 1993, the Muslim side had committed mass crimes against civilians and HVO soldiers in each of the three municipalities through organized military operations led by the ABiH and the Ministry of the Interior BiH (MUP) units who were also mostly Muslim units. The HVO response to these attacks was reduced to undertaking minor or major counterattacks in order to stop further advance of the SUMMARY ABiH. Accordingly, after several months of mostly defensive activities, in the last months of 1993 and early 1994, the HVO conducted two relatively unsuccessful offensive operations in the Prozor municipal area with the aim of unblocking its own forces in central Bosnia. On that occasion, the progress they made was not comparable to the military successes of the ABiH in the areas of Jablanica and Konjic, as ABiH placed these areas almost completely under its control.
