The aim of this thesis is to gather available sources concerning the legal order of the Evangelical Church of Czech Brethren (ECCB) since its establishment in 1918 to the present day. The sources used address the legal history of the Protestant Church in Cisleithania from 1848 until the end of World War I.
A critical analysis of the sources is carried out to document the development of the church constitution and the orders of the ECCB. The criteria for the ela-boration of individual storylines are primarily the historical rele-vance and the practical applicability of the information regarding the ECCB Strategic Plan of 2019.
