Germany's political structure following World War I. The Constitution called for an elected President, a Chancellor (Prime Minister) appointed by the President, a Cabinet of Ministers appointed by the Chancellor, and an elected house of representatives, i.e. Parliament, called the Reichstag. The governing powers rested with the Chancellor through the ministry, with the President retaining veto powers and performing ceremonial duties. The Reichstag provided more of an advisory role than an actual legislative one.
