Corruption is a form of dishonesty or criminal offense undertaken by a person or organization entrusted with a position of authority, to acquire illicit benefit or abuse power for one's private gain. Corruption may include many activities including bribery and embezzlement, though it may also involve practices that are legal in many countries. Political corruption occurs when an office-holder or other governmental employee acts in an official capacity for personal gain. Corruption is most commonplace in kleptocracies, oligarchies, narco-states and mafia states.
