The title "Mistress of the New Poetry" is often associated with Sylvia Plath, a prominent American poet known for her intense and confessional style. Plath's work, particularly her collection Ariel, revolutionized modern poetry by exploring themes of identity, mental illness, and the female experience. Her innovative use of language and imagery has inspired countless poets and writers. This title can also refer to the broader movement of Confessional Poetry, which emerged in the mid-20th century. This genre emphasizes personal experience and emotional depth, often blurring the lines between the poet's life and their work. Other notable poets in this movement include Robert Lowell and Anne Sexton.
