I didn't attempt that kind of thing again for a long time." Moving her family to New York in 1966, Rich became involved with the New Left and became heavily involved in anti-war, civil rights, and feminist activism. Her husband took a teaching position at City College of New York. In 1968, she signed the "Writers and Editors War Tax Protest" pledge, vowing to refuse tax payments in protest against the Vietnam War. Her collections from this period include Necessities of Life (1966), Leaflets (1969), and The Will to Change (1971), which reflect increasingly radical political content and interest in poetic form. From 1967 to 1969, Rich lectured at Swarthmore College and taught at Columbia University School of the Arts as an adjunct professor in the Writing Division.
