International relations is a valuable field of study because it involves a variety of disciplines, including foreign language, social sciences, law, history, economics and politics. International relations students value the relationship between different cultures and believe the actions of a group of people can impact the world as a whole.
According to Lehigh University, international relations is usually part of a university's political science program, but because of its cross-disciplinary nature, some schools choose to create a separate major devoted solely to the major. Subfields include international security, international political economy and the relation of international organizations to law. Aspiring politicians and humanitarians find this major particularly useful.
