5.2 Four theories

International Relations theories are sets of ideas, assumptions or claims that can be grouped together into different traditions. Studying IR theories might be quite challenging at first due to their perceived complexity. However, theories are valuable tools that simplify and clarify different ideas and help us to understand and explain international relations. They can also help us to explain, predict, describe and critique relations among and between actors in international relations. Placing theories in dialogue with one another also brings to the surface their strengths and limitations. You will now be introduced to four theoretical traditions, namely, realism, liberalism, constructivism and postcolonialism.
