Black–blue coalition

The term black-blue coalition or blue-black coalition refers, especially in Austria and Germany, to a cooperation between Christian democratic- conservative (“centrist”) and national conservative (“right-wing”) parties.

In the Germanosphere, the name of the coalition refers to the party colours (German: Schwarz-blaue Koalition)

In Austria, this term (here also turquoise-blue coalition or blue-turquoise coalition) refers to a coalition between the black (since 2017 turquoise) Austrian People's Party (ÖVP) and the blue Freedom Party of Austria (FPÖ). Nationwide, such a coalition was first formed from February 2000 to April 2005 by the Schüssel I and Schüssel II federal governments. After the 2017 National Council elections, the ÖVP and FPÖ formed a coalition again from December 2017 to May 2019 (Kurz I federal government). At the state level, there has been a black-blue working agreement within the framework of a proportional government in Upper Austria since October 2015 (Pühringer V state government, Stelzer I state government, Stelzer II state government) and in Lower Austria since March 2023 (Mikl-Leitner III). On 24 May 2023, the Governor of Salzburg State, Wilfried Haslauer, announced the successful formation of a black-blue coalition (Haslauer Jr. third government) following the 2023 Salzburg state election.

In Germany, after 1919, "black-blue" electoral alliances and later coalition governments between the Centre Party ("black") and Protestant liberal-conservative parties ("Prussian-blue") emerged in Württemberg. In the Federal Republic, a possible cooperation between the Christian Democratic Union of Germany (CDU) ("black") and the Alternative for Germany ("blue") has been referred to as a black-blue coalition.
