Elections in Germany include elections to the Bundestag (Germany's federal parliament), the Landtags of the various states, and local elections.
Several articles in several parts of the Basic Law for the Federal Republic of Germany govern elections and establish constitutional requirements such as the secret ballot, and requirement that all elections be conducted in a free and fair manner. The Basic Law also requires that the federal legislature enact detailed federal laws to govern elections; electoral law(s). One such article is Article 38 which is regarding the election of deputies in the federal Bundestag. Article 38.2 of the Basic Law establishes universal suffrage: "Any person who has attained the age of eighteen shall be entitled to vote; any person who has attained the age of majority may be elected."
German federal elections are for all members of the Bundestag, which in turn determines who is the Chancellor of Germany. Federal elections were held in 2009 and in 2013.
After the unification of Germany under Emperor Wilhelm I in 1871, elections were held to the German Reichstag or "Imperial Assembly", which supplanted its namesake, the Reichstag of the Norddeutscher Bund. The Reichstag could be dissolved by the Kaiser or, after the abdication of Wilhelm II in 1918, the Reichspräsident. With the Weimar Republic's Constitution of 1919, the voting system changed from single-member constituencies to proportional representation. The election age was reduced from 25 to 20 years of age.Women's suffrage had already been established by a new electoral law in 1918 following the November Revolution of that year.
