History
History of Massachusetts Peace Action
From the nuclear disarmament campaigns of the Cold War to today’s organizing for diplomacy, climate survival, and human security, MAPA’s work has grown from a clear demand: choose people over war.

Overview
National roots, Massachusetts organizing
Peace Action and Massachusetts Peace Action share a history rooted in nuclear disarmament, grassroots pressure, and public education.
Peace Action’s national roots
Peace Action began in 1957 as the Committee for a Sane Nuclear Policy, known as SANE. The Nuclear Weapons Freeze Campaign began in 1980 in Massachusetts and soon became a national movement. SANE and Freeze merged in 1987 to form SANE/Freeze, then changed its name to Peace Action in 1993.
MAPA’s statewide role
Massachusetts Peace Action began in the 1980s as Massachusetts Freeze, an affiliate of the nationwide Nuclear Weapons Freeze Campaign. Since becoming Massachusetts Peace Action in 1993, the organization has continued nuclear disarmament work while broadening its focus to peace, diplomacy, social justice, and a smaller Pentagon budget.
