Mecklenburg (1945–1952)
The State of Mecklenburg () was a subdivision of the Soviet occupation zone (until 1949) and one of the states of East Germany (from 1949) which corresponds widely to the present-day German state Mecklenburg-Vorpommern. The state was originally formed as an administrative division, the State of Mecklenburg-Vorpommern (), by the Soviet Military Administration in Germany (SMAD) in July 1945. It consisted of the 1934-established Mecklenburg (a merger by the Nazi Gauleiter Friedrich Hildebrandt of the free states of Mecklenburg-Schwerin and Mecklenburg-Strelitz) and parts of the former Prussian provinces of Pommern (Western Pomerania to the  Oder–Neisse line) and Hanover (Amt Neuhaus). The city of Swinemünde (now Świnoujście) was handed over to Poland in October 1945, becoming part of Szczecin Voivodeship. In November 1945, a transfer of small territories along the Inner German border to the former Province of Schleswig-Holstein was carried out as part of the Barber–Lyashchenko Agreement. About 2.1 million people were estimated to live in Mecklenburg in 1946. From 1947, the term "Vorpommern" was excluded from the official name as the SMAD feared that this would support revisionist actions against formerly German parts of Poland (in particular Farther Pomerania). Compared  to the administrative divisions of Nazi Germany, Mecklenburg comprised the "Gaue" Mecklenburg and parts of Pomerania and Eastern Hanover. Due to the post-war situation in Germany, the SMAD appointed state administrations in all subdivisions of their occupation zone in July 1945. Wilhelm Höcker became the president of the state administration in Mecklenburg and was later elected minister-president. The first election for the state diet, the Landtag of Mecklenburg-Vorpommern, was held on 20 October 1946, on the same day the elections for the "Landtage" of the other divisions in the Soviet occupation zone were held. The Soviet-backed  SED (which became the ruling party of East Germany from 1949 onwards) received 49.5% of the votes, CDU 34.1%, LDPD 12.5% and VdgB 3.9%. In February 1947, a state constitution was adopted. However, all resolutions by the parliament were made subject to approval of the SMAD. After the foundation of the German Democratic Republic (GDR) in October 1949, a second election for the Landtag was held in October 1950. The only party was the National Front, an alliance of political parties and mass organisations controlled by the SED, which received 99.9% of the votes. Following this election, four members of  the Landtag were sent to the Chamber of States ("Länderkammer") of East Germany for the first and only time. As the ruling communists aimed to build a quasi-unitary state, Mecklenburg was in effect dissolved by a change of the Constitution of East Germany in July 1952. All of the five East German "Länder" were replaced by 14 newly formed regional districts ("Bezirke"). In case of Mecklenburg, the territory was transferred to the regional districts of Neubrandenburg, Rostock and Schwerin. While Mecklenburg and the other "Länder" formally remained in existence, they no longer had any political or administrative function. The  Chamber of States remained in existence and its members were elected in 1954 by combined sessions of the district assemblies ("Bezirkstage") in each "Land" and in 1958 directly by the district assemblies. However, on 8 December 1958, the Chamber of States and the "Länder" were both formally dissolved with no objections raised. The abolition of the Chamber of States in 1958 and the ratification of two new constitutions in 1968 and 1974 respectively finally eliminated all forms of federalism in East Germany until the peaceful revolution in 1989. After the first free elections in East Germany, the "Ländereinführungsgesetz" (State Establishment  Act), adopted on 22 July 1990 by the Volkskammer, recreated the "Länder" in the German Democratic Republic that had been abolished in 1952. However, since changes to the boundaries of municipal districts were not reversed, and also due to considerations of expediency, these new "länder" were formed by merging the "kreise" of East Germany. As a result, their borders differed from the ones prior to 1952. The new Mecklenburg-Vorpommern was formed from the East German "Bezirke" of Mecklenburg-Vorpommern, Neubrandenburg, Rostock and Schwerin without the "Kreise" of , and . Originally, the "Ländereinführungsgesetz" was supposed to come into force on 14  October. This date was changed to 3 October, the date of German reunification, by the German reunification treaty ("Einigungsvertrag"). As it did not come into force before reunification, these parts of the act were immediately superseded by the corresponding articles of the Basic Law and never had any significance. On 14 October 1990, elections to the "Landtage" (state parliaments) were held in Mecklenburg-Vorpommern and the four other new states, initiating the formation of state governments.
