Wilde swears a criminal-libel prosecution against the Marquess of Queensberry

Read the full account
On 18 March 1895 Oscar Wilde opened a criminal-libel prosecution over Queensberry’s visiting card. It is not the later Crown case under the Labouchere Amendment.
Context
He could have declined to sue. He sued. The collapse of that prosecution opened the indecency trials.
Oscar Wilde’s documented role is bounded by other offices and collaborators named in the sources below.
Why it matters
The libel writ is not Reading Gaol, and not the Crown’s two later trials.
