The phrase "the pen is mightier than the sword" is commonly associated with the idea that written words and ideas are more powerful and effective in influencing people and shaping history than violent force. This sentiment was popularized by British politician Edward Bulwer-Lytton in his play "Richelieu; Or the Conspiracy," written in 1839. The phrase emphasizes the power of communication, persuasion, and intellect over brute strength and military might. Throughout history, figures who used their words to inspire change, advance social justice, or articulate ideological movements exemplify this principle, illustrating literature's enduring influence on society.
