On October 14, 1889, the "Konference der Vereinigten Mennoniten-Brueder von Nord America" was founded in Mountain Lake. Elder Aaron Wall, founder of the Bruderthaler Church of Mountain Lake and Elder Isaac Peters of the Ebenezer Church of Henderson, Nebraska were instrumental in the establishment of this new Mennonite denomination. Known today as the "Fellowship of Evangelical Bible Churches" (FEBC), for many years the conference was popularly called the Bruderthaler Conference, because of the influential nature of the Mountain Lake founding church. In 1914 the name was officially changed to "The Defenceless Mennonite Brethren in Christ of North America". The name was changed once again, in 1937, to "Evangelical Mennonite Brethren" (EMB). The denominational headquarters was located in Mountain Lake until 1956.
