The original Carrington–Cutileiro peace plan, named for its authors Lord Carrington and Portuguese ambassador José Cutileiro, resulted from the EC Peace Conference held in February 1992 in an attempt to prevent Bosnia-Herzegovina sliding into war. It was also referred to as the Lisbon Agreement (). It proposed ethnic power-sharing on all administrative levels and the devolution of central government to local ethnic communities. However, all Bosnia-Herzegovina's districts would be classified as Bosniak, Serb or Croat under the plan, even where no ethnic majority was evident. In later negotiations, there were compromises about changing district borders. On 3 March 1992, Bosnia and Herzegovina was declared independent following a referendum held days earlier on February 29 and 1 March.
