The exact sentence was coined by Lytton in 1839 for his play Richelieu; Or the Conspiracy.[1][2] The play was about Cardinal Richelieu, though in the author’s words “license with dates and details … has been, though not unsparingly, indulged”.[1] The Cardinal’s line in Act II, scene II, was more fully:[3]
True,—This!
Beneath the rule of men entirely great
The pen is mightier than the sword. Behold
The arch-enchanters wand!— itself a nothing!—
But taking sorcery from the master-hand
To paralyse the Cæsars—and to strike
The loud earth breathless!—Take away the sword—
States can be saved without it![4]
The play opened at London’s Covent Garden Theatre on 7 March 1839 with William Charles Macready in the lead role.[5] Macready believed its opening night success was “unequivocal”; Queen Victoria attended a performance on 14 March.[5]
In 1870, literary critic Edward Sherman Gould wrote that Bulwer “had the good fortune to do, what few men can hope to do: he wrote a line that is likely to live for ages”.[2] By 1888 another author, Charles Sharp, feared that repeating the phrase “might sound trite and commonplace”.[6] The Thomas Jefferson Building of the Library of Congress, which opened in 1897, has the adage decorating an interior wall.[7][8] Although Bulwer’s phrasing was novel, the idea of communication surpassing violence in efficacy had numerous predecessors.
The saying quickly gained currency, says Susan Ratcliffe, associate editor of the Oxford Quotations Dictionaries. “By the 1840s it was a commonplace.”[9]
