Public administration is the single most important aspect of bureaucracies across the world; be it a democratic, socialist or a capitalist state, more so in a socialist state, as all aspects of the citizen life are influenced and decided by the government.

There has been considerable shift in the way the public administration was carried out in ancient and medieval times when the initiatives were nothing more than sporadic administrative functions like maintaining law and order and collecting revenues with little or no welfare activities. The people who carried out those activities were selected by the monarchs and were no better than their personal servants.

With changing times, the objective of public administration also underwent a change and by the nineteenth century; an organized approach to public servants and public administration was adopted. This approach was based on an exhaustive legal framework replacing the patriarchal and hereditary function with bureaucracy.
