Introducing the readings:

This unit’s readings provide an introduction to international law. To define and connect key concepts, Traisbach (2017) discusses sources and applications of international law. This reading also distinguishes international law from domestic law, as the former faces unique problems of implementation and enforcement.

Two additional readings offer examples of international law at work. The United Nations Convention on the Law of the Sea (UNCLOS) is a major international law governing maritime rights. UN (2012) provides an historical overview of how this convention came into existence.

International law is also a very dynamic and growing field of action and advocacy. One young international court, the International Criminal Court, was founded in 2002. It is today the only international court to investigate and prosecute certain crimes against humanity. ICC (2019) offers an overview of how this court works to address these international crimes.
