A Great Person is a unit representing a uniquely talented individual. Great People (GPs) have many powerful abilities. All GPs can be settled in a city, becoming a super specialist of their respective type. All GPs except Great Generals can also start a Golden Age. In addition, most Great People can help discover a technology (bulbing), some Great People have a special building that only they can build in a city, and most kinds of Great People have a special operation which they can perform in a city. For the list of great persons, see List of historical figures in Civilization IV.
