Ferdinand VII of Spain
>”haha suck it liber*ls, I’m back and I’m revoking the Constitution of 1812!”
>This immediately triggered a million revolts
>Lost almost all of Spain’s colonies
>Rejected the crown of Mexico, killing the last chance of forming a Spanish Commonwealth
>Refused to modernize the economy
>Died leaving his daughter a bloody civil war
