Constitution of Prussia (1920)
The Constitution of Prussia (German: Verfassung von Preußen), was the constitution of the Free State of Prussia. It came into effect on 30 November 1920. It was formally dissolved along with Prussia itself in 1947 though in practice it had been ineffectual since the Nazi Party's rise to power in 1933 and the Gleichschaltung
It established a parliamentary system with a bicameral legislature, the Landtag of Prussia, with the Abgeordnetenhaus as the lower house and the Prussian State Council as the upper house. The executive was led by the Minister President.
