Which poet coined the term 'War of roses'?

The term "War of Roses" was coined by the British poet William Shakespeare. He used it in his plays to describe the series of civil wars in England during the 15th century between the houses of Lancaster (symbolized by a red rose) and York (symbolized by a white rose). Although the phrase itself was popularized by Shakespeare, it has since become a historical reference to this tumultuous period in English history.
