The 1850 Constitution of Prussia was an amended version of the 1848 Constitution. Unlike the earlier version that King Frederick William IV had unilaterally imposed on the Kingdom of Prussia on 5 December 1848, the 1850 revision was a cooperative effort between the new Prussian Parliament, the King and his ministers. The changes they made to the 1848 Constitution were mostly relatively minor. The king remained in a position of dominance over the three branches of government, and Parliament had no control over the military, but liberal elements such as the catalogue of fundamental rights, the introduction of jury courts and certain limitations on the monarch's power remained in place.
The 1850 Constitution, frequently modified, was the fundamental law of Prussia until the end of the German Empire in 1918.[1]
