Answer:
Megalomania comes from the Greek megas ("great") and mania ("madness"). It is a madness of greatness, but not a great kind of madness! Megalomaniacs in history include Alexander the Great, Genghis Khan, and Napoleon Bonaparte. People with megalomania tend to exaggerate their virtues and never see their faults. One of the most megalomaniacal would probably be Joseph Stalin.
