The International Community of Mennonite Brethren was officially launched at the 1990 Mennonite World Conference in Winnipeg, Manitoba as a partnership of global Mennonite Brethren conferences. ICOMB was originally conceived by leaders of MBMS International at an international mission consultation in Curitiba, Brazil in 1988. ICOMB functions as a framework for Mennonite Brethren conferences worldwide to relate as peers rather than as mission churches under the structure of MBMS International. In 2005 the term "committee" was officially changed to "community" by the conference representatives assembled at ICOMB's annual leadership summit in Japan. In 2005, Victor Wall, president and representative of the Paraguay-German Mennonite Brethren Conference, was chosen to be the first Executive Secretary of ICOMB. He completed his term in 2010. In 2011, David Wiebe of Canada was chosen to be Executive Secretary. He had resigned from his position as Executive Director of the Canadian Conference of Mennonite Brethren Churches in 2010. In 2018 Rudi Plett of the Paraguay-German Mennonite Brethren Conference, who had chaired the ICOMB Executive Committee 2011-2017, and then served as Associate Director overseeing the Latin American churches, was chosen to be Executive Secretary. Membership ICOMB members are national associations of Mennonite Brethren churches, also known as conferences. Names of members are listed by continent.
