International Relations (IR) is sometimes also called World Affairs or Global Politics. IR looks at the relationships between states and other actors on the world stage. It looks at how the relations between these actors function and affect societies. This paper will provide students with a number of theories to understand and analyse IR in current or past events. It will provide students with an overview of the history of IR. As a multi-disciplinary subject, it is therefore expected that students will acquire a good general knowledge. The focus of this paper will be on “Globalization”, as it is one of the issues students can experience in their daily life. IR is a specialization at the undergraduate level and a specific programme leading to a diploma or masters degree at the graduate level. Studying IR, may prepare students for careers in government, diplomacy, trade or humanitarian work.
