Answer
The pen is mightier than the sword is a proverb that suggests that intellectual power and influence can be more effective than physical force or brute strength. Edward Bulwer-Lytton, a British novelist and politician, coined the phrase in his 1839 novel "Richelieu". The proverb has been used to describe the power of writing, journalism, and other forms of communication to influence public opinion and bring about social change.
