The Hussite movement that was to become the Moravian Church was started by Jan Hus () in early 15th century Bohemia, in what is today the Czech Republic [REF].
Within fifty years of Hus' death, a contingent of his followers had become independently organised as the "Bohemian Brethren" (Čeští bratři) or Unity of the Brethren (Jednota bratrská), which was founded in Kunvald, Bohemia, in 1457.
