The concept of Black Power . . . is a call for Black people to define their own goals, to lead their own organizations and to support those organizations. It is a call to reject the racist institutions and values of this society. The concept of Black Power rests on the fundamental premise: Before a group can enter the open society, it must first close ranks. By this we mean that group solidarity is necessary before a group can operate effectively from a bargaining position of strength in a pluralistic society.
