Throne of the Mexican Emperors

Today seen in the Cathedral of Mexico City, along with their remains.

Both emperors were forcibly deposed and executed.

With the declaration of independence of the Mexican Empire from Spain after 300 years in 1821, Mexico became an independent monarchy.  It should have stayed that way.  The monarchy was soon after replaced.
