In Germany and Switzerland, a Landeskirche (; plural: Landeskirchen, ) is the church of a region. The term usually refers to Protestant churches, but—in case of Switzerland—also Roman Catholic dioceses. They originated as the national churches of the independent states, States of Germany (Länder) or Cantons of Switzerland (Kantone, Cantons, Cantoni), that later unified to form modern Germany (in 1871) or modern Switzerland (in 1848), respectively.
Origins in the Holy Roman Empire In the pre-Reformation era, the organization of the church within a land was understood as a landeskirche, certainly under a higher power (the pope or a patriarch), but also possessing an increased measure of independence, especially as concerning its internal structure and its relations to its king, prince or ruler. Unlike in Scandinavia and England, the bishops in the national churches did not survive the Reformation, making it impossible for a conventional diocesan system to continue within Lutheranism. Therefore, Martin Luther demanded that, as a stop-gap, each secular Landesherr (territorial lord, monarch or a body, like the governments of republican Imperial estates, such as Free Imperial Cities or Swiss cantons) should exercise episcopal functions in the respective territories. The principle of cuius regio, eius religio also arose out of the Reformation, and according to this a Landesherr chose what denomination his subjects had to belong to. This led to closed, insular landeskirchen. The principle was a byproduct of religious politics in the Holy Roman Empire and soon softened after the Thirty Years' War.
At the time of the abolition of the monarchies in Germany in 1918, the Landesherren were summus episcopus (Landesbischöfe, comparable to the Supreme Governor of the Church of England) in the states or their administrative areas, and the ties between churches and nations came to be particularly close, even with Landesherren outside the Lutheran church. So the (Roman Catholic) king of Bavaria was at the same time supreme governor (summus episcopus) of the Evangelical Lutheran Church in Bavaria right of the river Rhine. In practice, the Landesherren exercised episcopal functions (summepiscopacy) only indirectly through consistories ( [sg./pl.]).

List of Landeskirchen in 1922 with changes until 1945 Those of the following Landeskirchen, which existed in 1922, founded the new umbrella German Evangelical Church Confederation (, 1922–1933). There were mergers in the 1920s and under Nazi reign in 1933 and 1934.
The first date given before every entry in the table below refers to the year, when the respective church body was constituted. Such a date of constitution is somewhat difficult to fix for the 19th century, when church constitutions were reformed and came into effect, which usually provided for more or less state-independent legislative and executive bodies more or less elected by parishioners. The Protestant Reformation and some church organisation (Kirchenordnung) of course existed long before.
For the 20th century the given years refer to the formal establishment of the respective church body. The second date refers to the year, when the respective church body ceased to exist (if so), due to a merger or unwinding. The third entry gives the name of each church body alphabetically assorted by the first territorial entity mentioned in the name. This makes sense because Landeskirchen have clear regional demarcations, therefore usually somehow mentioned in their names. The post-World War I church bodies, listed below, have never existed all in the same time. One can sort the table below alphabetically or chronologically by clicking on the button with the gyronny of four.

In 1918 the Reformed congregations earlier subsumed within the Bavaria church body seceded and founded the independent Evangelical Reformed Church in Bavaria (see Further Protestant church bodies in Germany). On 1 April 1921 the Evangelical Lutheran State Church of Saxe-Coburg merged in the Bavaria church body. The new name replaced the prior Protestant State Church in the Kingdom of Bavaria right of the river Rhine in 1921, when the new church constitution accounted for the Kingdom having become a republic and the Reformed congregations having formed a separate church body. The Bavaria official church body remained an intact church (), since the Nazi-submissive German Christians remained a minority in the synod after the unconstitutional election imposed by Hitler on 23 July 1933. Nazi opponents of the Confessing Church could act within the church body. 1843 1934 BirkenfeldEvangelical Church of the Region of Birkenfeld United by confession parishioners (1922)The Oldenburgian exclave of the Region of Birkenfeld.
