Unless somebody wishes to lay claim i have a fun idea.
Great Hungary
A kingdom founded after the Apocalypse to restore the great Hungary to its former glory.

The punchline? They're actually in America, somewhere around the Yellowstone Park. History itself got distorted so much that they don't even realize this.
Well, that and the influence of a madman from the past.

If I may bring in a suggestion, maybe have something like Caesars legion in the original Fallout Universe. Have this guy proclaim to be the reincarnation or descendant of the original leader of Greater Hungary and that he shall bring greatness to his Empire once again.
