Boundaries are the framework of a nation. The location of boundary determines the rules and laws that the people have to follow, the national culture with which they would be identified with, and many other such things.  Boundary questions have often led to war in the history for numerous reasons. Before one delves deeper into this subject, one needs to define the terms that are often used as synonyms: boundary and border. To sum up, boundary is to be defended in times of war; border has to be patrolled in times of peace to prevent illegal immigration and to control smuggling, trafficking etc; and needs to be consolidated by evolving appropriate socio – economic and political policies[i]. Boundaries perform a variety of functions, namely, political, strategic, administrative and cultural and also have a psychological, economic, cultural, anthropological and a strategic significance.
