purge

In history, religion, and political science, a purge is the removal of people who are considered undesirable by those in power from a government, from another organization, from their team owners, or from society as a whole. A group undertaking such an effort is labeled as purging itself. Purges can be either peaceful or violent; with former often resolved by simple removal from office, and latter with the imprisonment, exile, or deaths of those purged. Restoring people who have been purged is known as rehabilitation.
