The modern world order refers to the international system that has emerged since the end of World War II and the collapse of colonialism. This system is characterized by a number of key features, including the rise of the United States as the dominant global power, the spread of liberal democracy and the rule of law, and the growth of international organizations such as the United Nations and the World Trade Organization.

The formation of the modern world order was shaped by a number of historical events and processes, including the decolonization of much of the world in the post-war period, the Cold War between the United States and the Soviet Union, and the collapse of the Soviet Union and the end of the Cold War.

During this period, the world saw the emergence of a number of key trends and challenges, including the spread of globalization, the rise of non-state actors such as multinational corporations and international organizations, and the impact of technological change. These trends and challenges have had significant implications for the nature of the modern world order and the ways in which different actors interact with one another.

Overall, the formation of the modern world order has been a complex and multifaceted process that has shaped the contemporary international landscape and continues to influence the way the world functions today. Understanding the formation of the modern world order is essential for understanding the contemporary world and the challenges and opportunities it presents.
