International Relations

International relations is the study of interactions between sovereign states and the subject explains the behaviour that occurs across the boundaries of states. International relations emerged as a discrete field at the beginning of the 20th century when it was offered as an undergraduate major by Aberystwyth University in the UK. Initially, it was an extension of political science. International relations can be divided into two main fields: international security (the study of war, conflict, peace, etc.) and international political economy (international finance, trade, FDI, etc.).
