Neither the coalitions of the CDU/CSU and the Free Democratic Party (FDP) nor the ruling SPD and Alliance '90/The Greens had the vote of a majority of members of the Bundestag following the 2005 federal election, so the CDU/CSU and SPD decided to form the second grand coalition in the history of the federal republic.[2] Both CDU/CSU and SPD achieved a similar percentage of votes at the election (35.2% and 34.2%, respectively),[5] so they decided that each would receive eight cabinet seats (with six for the CDU and two for the CSU). On 13 October the SPD announced their future ministers and on 17 October the CDU/CSU announced theirs.[6]
Edmund Stoiber of the CSU was to become the Federal Minister of Economics and Technology, but refused the post on 1 November after a conflict with Angela Merkel over the abilities of the minister to succeed him, and chose to continue his state-level role in Bavaria.[7]
The coalition agreement (Koalitionsvertrag), titled Together for Germany. With courage and humanity, was signed and accepted by the congress of the CDU, CSU, and SPD on 12, 13, and 14 November.[3] Angela Merkel was elected Chancellor of Germany on 22 November 2005 by 397 votes to 202. From that date the cabinet was officially in power.[8]
