Welcome to International Relations at Sussex

International Relations investigates a wide range of international political issues – from war and inequality through climate change, international trade and global health to social movements like Black Lives Matter and foreign policies.

If you are interested in finding out where these issues come from historically, what their economic or security implications are, what kinds of theories account for them and what role different actors - from governments through rebel armies to social movements - and issues like race, gender, sex, class, religion, technology or violence play in them, then you are in the right place at Sussex. We investigate all facets of international politics from a variety of different angles with the aim to open up new ways of thinking about and addressing these problems.

Our Department is one of only four dedicated IR Departments in the country with well over 30 faculty and so you will be able to specialize in a huge range of international issues. We also practice what we preach: we are a global department, with faculty members and students from all over the world. Whether you are coming from Britain, Europe, Asia, Africa, the Americas or Australia, whether you have just left school or are returning to education, you will find like-minded people here and make new and interesting connections. So, join our friendly, inclusive and inspiring community at Sussex!

Global Studies - responding to the COVID-19 pandemic

MasksAcademics across the School of Global Studies are drawing on their wide-ranging research expertise to react and inform during the current Coronavirus outbreak.

From providing specialist insight on health policy to writing pieces for the UK and international media on migrant key workers, and debating the impact the virus might have on Brexit, our School’s research in Anthropology, International Relations, International Development and Geography can bring understanding, challenge and perspective to the crisis.
