Consistory in Berlin, and of the Reformed (Calvinist) congregations located in Pomerania and previously subject to the Reformed Church Directorate in Berlin. The King originally intended the merger of locally established Lutheran and Calvinist congregations into congregations of a United Protestant confession, and the adoption of the Union confession by all local congregations without an existing local partner of the other confession to merge with. His intention, however, failed due to strong Lutheran resistance throughout his monarchy, especially among Lutherans in Pomerania and Silesia. This fight even caused the schism of the Old Lutherans. A number of Lutheran congregations refrained to join the new umbrella or seceded from it in the 1820s and 1830s, forming the independent Evangelical Lutheran Church in Prussia recognised in 1845, which was why the Evangelical Church in Prussia renamed as Evangelical State Church in Prussia (Evangelische Landeskirche in Preußen), indicating its privileged status. So finally the merger, not including all congregations, materialised as a mere administrative Union, including in Pomerania mostly Lutheran congregations, the traditionally prevailing denomination, and some few Reformed and United Protestant congregations. Reformed congregations were usually found in cities or newly established or resettled villages in formerly Brandenburgian Pomerania, where Calvinist immigrants ensconced after 1685. United Protestant congregations usually emerged in cities, where Calvinists and Lutherans lived side by side and disliked the denominational split. The ecclesiastical province had its headquarters, the 1815-founded Royal [or Evangelical (as of 1918)] and general superintendent, domiciling in Stettin, taken over from the Brandenburgian Pomeranian Lutheran Church, the latter's local Köslin Consistory had been dissolved in 1815. The Swedish Pomeranian former Greifswald Consistory and the local were stripped of their competences and dissolved in 1849 and 1815, respectively, the general superintendency in Greifswald was not restaffed after 1824. Since initially the office of general superintendent was not provided as a function in the new Evangelical Church in Prussia at all, the respective offices had not been restaffed when their previous incumbents retired, causing a vacancy. However, since the late 1820s the Evangelical Church in Prussia appointed general superintendents in all its ecclesiastical provinces. Bismarck's church reforms strengthened the autonomy and self-rule of the state church, which in 1875 renamed as Evangelical State Church of Prussia's older Provinces (Evangelische Landeskirche der älteren Provinzen Preußens), since in Prussian provinces annexed since 1866 their regional Protestant church bodies had remained independent of the Evangelical State Church of Prussia.
