Merkel's first cabinet led the government of Germany from 22 November 2005 to 27 October 2009 throughout the 16th Bundestag. Led by Christian Democrat Angela Merkel, the first female chancellor in German history, the cabinet was supported by a grand coalition between the Christian Democratic Union (CDU), Christian Social Union of Bavaria (CSU), and the Social Democratic Party of Germany (SPD). It followed the Second Schröder cabinet. It ceased to function after the formation of Second Merkel cabinet, which was created after the 2009 federal elections, and was later sworn in on 28 October 2009.
The federal cabinet consisted of the following ministers:
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. Both CDU/CSU and SPD achieved a similar percentage of votes at the election (35.2% and 34.2%, respectively), 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.
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.
