Social organisation, the structural formation and set-up of every society is its foremost crusader against any social injustice in whatever hue. Man being a social being has always been and will always be part of social organisations. History of social organisation dates back to the very beginning of human history, and right from prehistoric times, it is seen and observed that a strong and united social organisation can singly and effectively achieve what the single and disunited cannot. Social grouping helped man to take on his common enemies like wild animals and people from other tribes or Gothras. Thus, Social organisations have been successful in eliminating the sense of insecurity or fear among any group or individual, as almost everybody in our society is a part of social organisation or group. Accessibility to justice and highest power centres once the purview of the privileged; the affluent and politicians are thus now available to the common man in society. This encyclopedia, in three volumes covering all aspects of social organisations and related topics makes authentic and interesting reading for all classes.
