While the Federal Republic has been famously characterized as a "grand coalition state," the Merkel government, formed in the after-math of the 2005 federal election, is only the second CDU/CSU-SPD coalition at the federal level since 1949. A comparison of the present administration with the first grand coalition government (1966-1969) reveals a wealth of differences that include some of the basic parameters of governing and governance in Germany, such as the structure of the party system and the overall public climate. Also, the personnel features and patterns of informal coalition governance under Chancellors Angela Merkel and Kurt-Georg Kiesinger display major differences. Arguably the single most important difference between the two administrations, however, relates to the level of public policy, with the Merkel government seeking to reverse some of the key decisions of its historical predecessor. Such u-turn dynamics have been particularly tangible in the field of federal system reform.
