Grand coalition (Germany)

In German politics, a grand coalition (German: Große Koalition [ˈɡʁoːsə koaliˈt͡si̯oːn] , shortened to: Groko [ˈɡʁoːkoː] ) is a governing coalition between the two parties with the most parliamentarians on federal or state level. The term is generally linked to a coalition between the centre-right CDU/CSU alliance (Union), consisting of the Christian Democratic Union (CDU) and the Christian Social Union of Bavaria (CSU) parties, and the centre-left Social Democratic Party (SPD), since they have historically been the major parties in most state and federal elections since 1949.
