1950 Hessian state election

The 1950 Hessian state election was held on 19 November 1950 to elect the 2nd Landtag of Hesse. The outgoing government was a grand coalition of the Social Democratic Party (SPD) and Christian Democratic Union (CDU) led by Minister-President Christian Stock, who retired at the election. He was succeeded as SPD lead candidate by Georg-August Zinn.

The SPD won a clear majority of seats thanks to quirks of the electoral system, which had been modified since 1946 to a form of mixed-member proportional representation. The Hessian CDU, who took a left-of-centre course in government with the SPD, were heavily defeated and pushed to third place with 19%. An alliance of the Free Democratic Party (FDP) and All-German Bloc/League of Expellees (GB/HBE) emerged as the second-largest party with 32%, but were unable to prevent the SPD from achieving its majority. Further, the Communist Party (KPD) slipped just below the 5% electoral threshold and lost their seats. After the election, Minister-President Stock retired and was succeeded by justice minister Georg-August Zinn, who led an SPD majority government.

Electoral system
The Landtag was elected via mixed-member proportional representation. 48 members were elected in single-member constituencies via first-past-the-post voting, and 32 then allocated using compensatory proportional representation. A single ballot was used for both. An electoral threshold of 5% of valid votes is applied to the Landtag; parties that fall below this threshold are ineligible to receive seats.

Background
In the previous election held on 1 December 1946, the SPD remained the largest party with 43%, followed by the CDU on 31%, FDP on 16%, and KPD on 11%. The SPD subsequently formed a grand coalition with the CDU.
