A republic may be defined, or at least named, as a government deriving its powers from the people and run by officials with limited or conditional tenure

If we resort for a criterion to the different principles on which different forms of government are established, we may define a republic to be, or at least may bestow that name on, a government which derives all its powers directly or indirectly from the great body of the people, and is administered by persons holding their offices during pleasure, for a limited period, or during good behavior.
