Joseph Martin "Joschka" Fischer is a German retired politician of Alliance 90/The Greens. He served as the foreign minister and as the vice chancellor of Germany in the cabinet of Gerhard Schröder from 1998 to 2005. Fischer has been a leading figure in the German Greens since the 1970s, and according to opinion polls, he was the most popular politician in Germany for most of the Schröder government's duration. Following the September 2005 election, in which the Schröder government was defeated, he left office on 22 November 2005. In September 2010, he supported the creation of the Spinelli Group, a Europarliamentarian initiative founded with a view to reinvigorate efforts to federalise the European Union.

Federal elections were held in Germany on 18 September 2005 to elect the members of the 16th Bundestag. The snap election was called after the government's defeat in the North Rhine-Westphalia state election, which caused them to intentionally lose a motion of confidence to trigger an early federal election. The outgoing government was a coalition of the centre-left Social Democratic Party of Germany (SPD) and Alliance 90/The Greens, led by federal Chancellor Gerhard Schröder. The election was originally intended for the autumn of 2006.
