Izetbegović consistently promoted the idea of a multi-ethnic Bosnia under central control, which seemed a hopeless strategy under the circumstances. The Bosnian Croats, disillusioned with the Sarajevo government and supported militarily and financially by the Croatian government, increasingly turned to establishing their own ethnically based state of "Croatian Republic of Herzeg-Bosnia" in Herzegovina and Central Bosnia. The Croats pulled out of the Sarajevo government and fighting broke out in 1993. In some areas local armistices were signed between the Serbs and Croats. Croat forces launched their first attacks on Bosniaks in central Bosnia in June 1992, but these failed. The Graz agreement caused deep division among Bosnian Croats and strengthened separatist Herzeg-Bosnia, and led to the Lašva Valley ethnic cleansing campaign against Bosniak civilians from May 1992 to March 1993.
