From the big bang of the international order with the emergence of the first nation-state in history around 3000 B.C and the interactions between those nations through wars, trade, transfer of technology, migration, and diplomacy, the world has witnessed endless circles of evolution of such international order influenced heavily by different factors, including wars, technology and inventions, climate change and its effects of migration and disasters and shortages of food and water, and the change of balance of power with the rise and fall of empires, as we have witnessed in the previous part. Such evolution is a normal and natural phenomenon of the world, with the fall of the Egyptian and Hittite Empires and the Rise of the Persianas and Greeks, and their fall and rise of the Romans and of the Han and Tang and Song Dynasties in China, and the fall of the Romans and Rise of the Islamic Empire, and the Rise of the Germanic tribes at the expense of the decaying Roman Empire, and the Rise of Mongols and Fall of Islamic Arab Empire, and the Rise of the Turkish Ottomans and fall of Holy Roman Empire and the capture of Constantinople, and the European Wars ended by the Peace of Westphalia and the aftermath of Napoleonic Wars and colonialist wars in the Americas, Asia, and Africa and two world wars and the so called Cold War and fall of Soviet Union in 1991 and the beginning of unipolarity and globalization in the 1990s, all these were circles illustrating the evolution of the international order.
