#1.It is not simple to present the satisfying definition of social movements. To clarify any confusion about this matter, I am going to give definitions of collective behavior and social movement; collective behavior is defined as activity involving a relatively large number of people that is often spontaneous and very typically in violation of established social norms.

Rather, the movement sought to change official norms that maintained segregation and institutionalized racism and then to change informal norms that supported the habitual racist behaviors of individuals. The movement made its demands for normative and behavioral changes on the basis of facts, supported by scientific and social sciences research results that demonstrated the falseness of certain long-standing beliefs held by many members of the society.

One good example to demonstrate reform movements is Nashville sit-ins movement (1959-1961). On February 1. 1960, fou...
