The Bull also defined a process to end disputes over imperial elections. The second part of the Bull consisting the final eight chapters was issued at the Diet of Metz on December 25, 1356. The Golden Bull remained a central part of the Holy Roman Empire's constitution until its dissolution in 1806.
