Quarrelling and protesting: How organizers shape a demonstration

On February 15, 2003, about 20 million people around the world protested against the imminent war in Iraq. In the Netherlands, 70,000 people marched in the streets of Amsterdam. This study focuses on the organization and mobilization processes preceding this event in Amsterdam. We trace how the organizers' attempts to form a coalition and the quarrels that ensued affected mobilization efforts, composition of the demonstration, media attention, and, subsequently, how and when participants were mobilized. We argue that, although infrequently studied, the specific ways that initial mobilization structures are formed are critical factors in the trajectory of mobilization. We use in-depth interviews with the organizers, newspaper content analyses, and survey data from participants to trace these effects.
