On 12 November 1991, on a meeting chaired by Dario Kordić and Mate Boban, local party leaders of the HDZ BiH reached an agreement to undertake a policy of achieving an "age-old dream, a common Croatian State" and decided that the proclamation of a Croatian banovina in Bosnia and Herzegovina should be the "initial phase leading towards the final solution of the Croatian question and the creation of a sovereign Croatia within its ethnic and historical [...] borders." On the same day, the Croatian Community of Bosnian Posavina was proclaimed in municipalities of northwest Bosnia in Bosanski Brod.
