The Bosnian Serb armyrenamed the Army of Republika Srpska (VRS) after the Republika Srpska state proclaimed in the Bosnian Serb-held territorywas fully integrated with the JNA. As 1992 carried on, it controlled about 70% of Bosnia and Herzegovina. This was achieved through a large-scale campaign of territorial conquest and ethnic cleansing which was backed by military and financial support from the Federal Republic of Yugoslavia. The war, which originally pitted Bosnian Serbs against non-Serbs, evolved into a three-sided conflict by 1993 when the CroatBosniak alliance deteriorated and the Croat–Bosniak war broke out. The Bosnian Croats declared a Herzeg-Bosnia state with the intent of eventually joining Croatia. This was incompatible with Bosniaks' aspirations of establishing a unitary state confronted by demands to partition the country. The VRS was involved in the Croatian War of Independence in a limited capacity, through military and other aid to the RSK, occasional air raids launched from Banja Luka, and most significantly through artillery attacks against urban centres, while the extent of territory it controlled did not change significantly until 1994.
