Peer Steinbrück is a German politician who was the Chancellor-candidate of the Social Democratic Party (SPD) in the 2013 federal election. Steinbrück served as the eighth Minister-President of North Rhine-Westphalia from 2002 to 2005, a member of the Bundestag from 2009 to 2016, and as Federal Minister of Finance in the first Cabinet of Chancellor Angela Merkel from 2005 to 2009.

Federal elections were held on 22 September to elect the members of the 18th Bundestag of Germany. At stake were all 598 seats to the Bundestag, plus 33 overhang seats determined thereafter. The Christian Democratic Union of Germany/Christian Social Union of Bavaria (CDU/CSU) of incumbent chancellor Angela Merkel won their best result since 1990 with nearly 42% of the vote and nearly 50% of the seats, just five short for an overall majority. The Free Democratic Party (FDP) failed to meet the 5% vote electoral threshold in what was their worst showing ever in a federal election, denying them seats in the Bundestag for the first time in their history.
