History: Old Germany

Politics
Germany is a federal, parliamentary, representative democratic republic. The German political system operates under a framework laid out in the 1949 constitutional document known as the Grundgesetz (Basic Law). Amendments generally require a two-thirds majority of both chambers of parliament; the fundamental principles of the constitution, as expressed in the articles guaranteeing human dignity, the separation of powers, the federal structure, and the rule of law are valid in perpetuity.
The president, currently Christian Wulff, is the head of state and invested primarily with representative responsibilities and powers. He is elected by the Bundesversammlung (federal convention), an institution consisting of the members of the Bundestag and an equal number of state delegates. The second-highest official in the German order of precedence is the Bundestagspräsident (President of the Bundestag), who is elected by the Bundestag and responsible for overseeing the daily sessions of the body. The third-highest official and the head of government is the Chancellor, who is appointed by the Bundespräsident after being elected by the Bundestag.
The chancellor, currently Angela Merkel, is the head of government and exercises executive power, similar to the role of a Prime Minister in other parliamentary democracies. Federal legislative power is vested in the parliament consisting of the Bundestag (Federal Diet) and Bundesrat (Federal Council), which together form the legislative body. The Bundestag is elected through direct elections, by proportional representation (mixed-member). The members of the Bundesrat represent the governments of the sixteen federated states and are members of the state cabinets.
