The Bundestag (German pronunciation: [ˈbʊndəstaːk], "Federal Diet") is a constitutional and legislative body at the federal level in Germany. For its similar function, it is often described as a lower house of parliament along the lines of the US House of Representatives and the Canadian or the British House of Commons. The German constitution, however, does not define the Bundestag and the Bundesrat as the lower and upper houses of a bicameral legislature.
