A pseuonym is a fictitious name, also known as an alias, used as an alternative to a person's legal name. In most legal systems, a person can assume a different name for non-fraudulent purposes and use it as their legal name. In some cases, pseudonyms are adopted because it is part of a cultural or organizational tradition, as in the case of devotional names used by members of some religious orders and "cadre names" used by Communist party leaders such as Trotsky and Stalin.
