International law is a body of rules and principles that govern the relations between states, as well as interactions between states and international organizations and individuals. It encompasses a wide range of legal issues such as human rights, trade, environmental protection, humanitarian intervention, and the use of force. International law is mainly derived from treaties, customary practices, and judicial decisions, and is enforced through a variety of mechanisms including diplomatic negotiations, sanctions, and the International Court of Justice. It plays a crucial role in promoting peaceful relations between states and providing a framework for resolving disputes in the international arena.
