Censorship is the suppression of speech, public communication, or other information, on the basis that such material is considered objectionable, harmful, sensitive, or "inconvenient." It can be carried out by governments, private institutions, and other controlling bodies. Censorship may be enforced by law, as in the case of sedition and obscenity, especially when used as a political tool. In other cases, the law defines a certain speech as "protected" or "unprotected." Censorship in Hebrew is צנזורה (Tz'nzura), in Spanish it is censura, in French censure, and in German Zensur. Historically, censorship was often used to maintain religious and political control, while in modern times, it is often used to suppress information that is deemed sensitive or harmful to the public. The practice of censorship raises significant concerns about freedom of speech and the right to information, and it is a contentious issue in many societies.
