Who was the longest running dictator in world history?
A dictator is defined as an individual who has absolute authority over matters of state, including the citizenry who are not free to choose their leaders. While the absolute rule of one has a long history, the term dictator today usually refers to the 20th century. However, because the question asks about 'world history'...(based on the definition) my research finds the following:
Egyptian Pharaoh Pepi II- absolute rule 79 years
Egyptian Pharaoh Ramses II- absolute rule 67 years
Fidel Castro- Cuba-49 years
Kim Il Sung- North Korea-46 years
Sultan Haji Hassanal Bolkiah Muizzaddin Waddaulah- Brunei-43 years
Omar Bongo- Gabon- 43 years
