Why boycotts became a recognisable campaign form
Launch library · evergreen read

A boycott, the coordinated refusal to buy from or engage with a target, works by converting public disapproval into a measurable economic or reputational cost, giving a campaign leverage even when it lacks direct access to formal decision making power. That leverage does not depend on holding any office or formal position at all.
Its effectiveness depends heavily on coordination and visibility, since a boycott only exerts real pressure if enough people take part and if the target, and the wider public, actually know it is happening and why. Without that visibility, even a genuinely widespread boycott can pass almost unnoticed.
The boycott's basic logic, using collective economic choice as a form of pressure, has proven adaptable across very different contexts and eras, which is part of why it remains a recognisable and still frequently used campaigning tool today. Few tactics translate so easily across such different causes and periods of time.
