Germany's Weimar Constitution is signed into law.

The Constitution of the German Reich, usually known as the Weimar Constitution, was the constitution that governed Germany during the Weimar Republic era. The constitution created a federal semi-presidential republic with a parliament, the Reichstag, that was elected by universal suffrage using proportional representation. The appointed Reichsrat represented the interests of the federal states. The president of Germany had supreme command over the military, extensive emergency powers, and appointed and removed the chancellor, who was responsible to the Reichstag. The constitution included a significant number of civic rights such as freedom of speech and habeas corpus. It guaranteed freedom of religion and did not permit the establishment of a state church.
