This is a list of fictional Monarchs – characters who appear in fiction as the monarch of a fictional or real country. They are listed by country, then according to the production or story in which they appeared.
As the two sons of Pedro II died in infancy, it would have been more likely for his daughter Isabel to have been Empress as Dona Isabel, although the prospect of her succeeding to the Brazilian throne was a key factor in the overthrow of the Brazilian monarchy. It is possible that Pedro IV is a macguffin, the fictional paternal grandson of Pedro II or the son of another member of the House of Braganza and adopted successor to Pedro II.
No references are made to the status of Brazilian slavery, the complete abolition of which in 1888 was another factor in the overthrow of the Brazilian monarchy (the Confederacy in this alternate timeline having manumitted its slaves during the presidency of James Longstreet in the Eighteen Eighties).
After the death of the Führer of the Great German Reich, Kurt Haldweim, condolences from various world leaders (albeit Nazi puppets or sympathers) are reported by influential newscaster, Horst Witzleben. Amongst those mentioned is an unnamed Tsar of Bulgaria.
It is implied that the formation of the German Union instead of the German Empire allowed the House of Bonaparte to remain on the French throne.
Pippin Arnulf Héristal, a descendant of Charlemagne, is crowned as Pippin IV to provoke a rebellion.
The book mentions a German nation-state called Almaigne which is ruled by an Emperor. However, neither the identity of the Emperor nor the exact national boundaries of Almaigne are specified (although it could exclude the state of Brunswick-Brandenburg).
In the alternate 1976 depicted in the novel, amongst the numerous crowned heads of Europe attending the funeral of Stephen III of England is an unspecified King of Naples. This suggests that Italian unification never occurred as a result of the increased secular power of the Vatican in this timeline.
