Corruption is a form of dishonesty or a criminal offense that is undertaken by a person or an organization that is entrusted in a position of authority to acquire illicit benefits or abuse power for one's gain. Corruption may involve activities like bribery, influence peddling, embezzlement, and fraud as well as practices that are legal in many countries, such as lobbying. Political corruption occurs when an office-holder or other governmental employee acts in an official capacity for personal gain.
Historically, "corruption" had a broader meaning concerned with an activity's impact on morals and societal well-being: for example, the ancient Greek philosopher Socrates was condemned to death in part for "corrupting the young".
