What is International Law and Diplomacy?
Historical Background
The roots of international law can be traced back to ancient civilizations. However, modern international law began to develop in the 17th century with the rise of nation-states. The Treaty of Westphalia in 1648 is often considered a turning point.
It established the principle of state sovereignty. In the 19th and 20th centuries, international law expanded to cover new areas like human rights and environmental protection. The creation of the League of Nations after World War I was an attempt to create a system of collective security.
After its failure, the United Nations was established in 1945. Diplomacy has been practiced for centuries, but it has become increasingly important in the modern era due to globalization and the interconnectedness of nations. The development of international organizations has also provided new forums for diplomatic engagement.
