The term 'International' was used for the first time by Jeremy Benlham in the later part of the eighteenth century with regard's to the laws of nations. Consequently, the term international relations were used to define the official relations between the sovereign slates. However some scholars even included the economic, social and cultural relations amongst the states also within the purview of the subject. Thus there are broadly two views regarding the meaning of international relations. Those who take narrow view assert that international relations include only "the official relations conducted by the authorized leaders of the state". To them the relations between nations, other than the official relations, such as trade, financial intercourse, missionary activities, travel of students, cultural relations etc. do not fall in the domain of international relations. Prof. Dunn takes a narrow view of international relations and defines it as "the actual relations that take place across national boundaries or as the body of knowledge which we have of those relations at any given time."
On the other hand some scholars have taken a broad view of international relations and included apart from the official relations between states; all intercourse among states and all movements of people, goods and ideas across (he national frontiers, within its purview.
International relation is the scheme of study that covers the all matters and relations which are beyond the any any sovereign state, weather it is related to religious national, political, social,strategic or any other interest of countries is called international relation.
This is the branch of political science that concerned with relationship between two or more nations nor countries.
Its the official relations to the official sovereign states
Scholars have tended to ignore the distinction between international relations and international politics and treated them as identical. For example E.H .Cart, and Quincy Wright treat the two as identical. However, certain other textbook writers have tried to draw a distinction between these two terms. They regard the term 'international relations' as wider in scope and include in its study the totality of relations of any people and group in the world society.
They include within its purview all aspects of relations between countries and people, political or non-political, peaceful or war like, legal or cultural economic or geographic, official or non-official. In short they use the term, as Harold and Margaret Sprout put it "to designate all human behavior on one side of a national boundary affecting the human behavior on the other side of the country." Since the term 'relations' has variety of meanings as contacts, connections and action and reaction, the scholars have tended to define international relations as an action on the part of a group-state or government-directed towards another group which reacts to it. On the other hand the term 'international polities' connotes the politics of international community in a rather narrow sense concerning mainly diplomacy and the relations among states and other political units.
