Politics (from Greek: πολιτικά, translit. Politiká, meaning "affairs of the cities") is the process of making decisions that apply to members of a group.
Factions among yourselves; preferring such To offices and honors, as ne'er read The elements of saving policy; But deeply skilled in all the principles That usher to destruction.
Philip Massinger, The Bondman, Act I, scene 3, line
