The Golden Bull of 1356 was a decree issued by the Imperial Diet at Nuremberg and Metz headed by the Emperor Charles IV which fixed, for a period of more than four hundred years, important aspects of the constitutional structure of the Holy Roman Empire. It was named the Golden Bull for the golden seal it carried.

Imperial Diet (Holy Roman Empire)
The Imperial Diet was the deliberative body of the Holy Roman Empire. It was not a legislative body in the contemporary sense; its members envisioned it more like a central forum where it was more important to negotiate than to decide.
