All human beings are social animals. Every person in society is dependent on echo other to fill full needs. Certain needs of society are fundamental in nature and those are needed to be satisfied for the smooth running life. A set of type of behavior created for caring out such socially important functions are known as social institutions. Sociology studies such social institutions and their inter relations these institutions some time are mentioned as group and sometimes as schools, banks, hospitals etc. But in sociology, institutions do not have this meaning. According to social thinkers like Merryl and Eldrage, “Social institutions are Social moulds which are established to carry out basic social functions and establishes collective image of behavior of a person.” We can say that a set of accepted rules and regulations is known as institution. A set of public behavior low and customs which are structural around one of more functions which are interrelated. These are made up of social regulations and values. There is an arrangement of relations in social institutions. Marriage institution, economic institution, educational institutions, family institutions etc., these are some examples of social Learning Center.
This creation of any social institution is not deliberate or planned. It develops along with the development of society. Then it attends a specific structure in that specific period of society. Just as Learning Center is created informally, the regulations are also not written.
Social regulations include public behavior, public customs etc. these are unwritten. In Short, when way to satisfy needs standardizes, Learning Center are created. There is a definite objective behind a creation of an institution. Society has varied motives and for that different Learning Center are formulated, for e.g. Family Institution was established for child bearing and there upbringing for satisfaction financial needs, economic Learning Center and for social control and a unity religious institution are created. It means that evety institutions are formed for achieving specific goal. Every social institution has a particular symbol. The institution is recognized =by that symbol. This symbol is physical and abstract. In Hindu marriage institutions MangalSutra is a symbol; in chritien religion finger ring is a symbol. By this we come to know that nature of marriage institutions in India is not the same as the institutions in western countries.
Collective mediums or establishments are created for fulfilling the objectives which the institutions have. For e.g. there are many establishments from school to university to fulfill the objectives of an educational institution. This social institution plays very important role in development of a Human being. This institution is the need of each and every society.
