In 1848, the first parliament for all of Germany, the National Assembly (or Frankfurt parliament in English), voted for a provisional constitutional order. It also installed a Reichsverweser as a kind of provisional head of state. The Reichsverweser had the task to install the ministers.[2] The Reichsverweser and the Reichsminister together formed the Provisorische Zentralgewalt (provisional central power, also called imperial government).
