"The pen is mightier than the sword" is an expression indicating that the written word is more effective than violence as a means of social or political change. This sentiment has been expressed with metaphorical contrasts of writing implements and weapons for thousands of years. The specific wording that "the pen is mightier than the sword" was first used by English author Edward Bulwer-Lytton in 1839.
Under some interpretations, written communication can refer to administrative power or an independent news media.
