American society produces numerous social movements to address perceived problems affecting segments of the population or the population as a whole. An examination of the general development of social movements and of the leadership and membership of three current social movements--the Black Power movement, the Civil Rights movement, and the Pro-life movement--will serve to show the nature, development, and perhaps future of these movements. For a social movement to occur, the following must take place: 1) some members of society must share a grievance they want to correct;
2) they must have hope and think there is a possibility of success;
3) there is often a precipitating event that ignites these grievances and convinces the people that the time for action has arrived;
4) people are recruited through a network of attachments.
For a social movement to succeed, the following must occur:
1) it must achieve an effective mobilization of people and resources;
2) it must withstand or overcome external opposition;
3) the fate of the movement depends on enlisting external allies from other major groups;
4) the movement will tend to be embodied in several separate organizations which may cooperate but which often compete vigorously.
Stewart, Smith, and Denton (1989) further identify a social movement as having at least minimal organization, meaning we can identify leaders, membership, and one or more organizations.
