The Project Association of Multiethnic Cities of Southeast Europe came about within the framework of the Igman Initiative, a network of over 140 NGOs from Bosnia and Herzegovina, Croatia and Serbia and Montenegro, dedicated to the normalization of relations between the countries of the Dayton Triangle. The forerunner of this project was the micro project for building cooperation between the cities in the triangle Tuzla-Osijek-Novi Sad, based on the Agreement on Interethnic Tolerance. Since this model of cooperation between cities produced very good results following ratification, a regional campaign was initiated in 2003 to create ten new triangles, i.e. circles of cooperation in the entire region of Southeast Europe, based upon the Agreement on Interethnic Tolerance. During this campaign, sixty cities and an equal number of partner NGOs were engaged in the project. Almost all capitals, regional centers and other cities of Bosnia and Herzegovina, Croatia, Serbia and Montenegro, Macedonia, Albania, Bulgaria, Romania and Hungary are included in their number. The regional conference ‘TOLERANCE AND UNDERSTANDING ABOVE ALL – The Agreement on Interethnic Tolerance’, held July 6th 2004 in Belgrade was the conclusion of the campaign. At this conference, representatives from nearly fifty cities and their NGO partners signed the Agreement on Interethnic Tolerance. In addition, they agreed to found the Association of Multiethnic Cities of the region and they elected an initiative board to begin the work of the organization. This association will be a project itself and its main goal is to encourage and coordinate the cooperation of its members and carry out concrete projects fostering cooperation in such fields as economy, culture, and information. Membership will be open also to all multiethnic cities that wish to join later on.
