Mongolian Khagan, which means “Khan Of Khans” or “king of kings” within Mongol Khel, the Mongolian language, perhaps more commonly translated as “emperor”, Temüjin Borjigi who is more well renowned for his title than his name, a title which is often mistaken for his name, Genghis Khan (pronounced “jeng-giss” with “jeng” sounding like “Jenga” and “giss” sounding like “kiss” with a hard “s”) killed over 40,000,000 (40 million) people during his reign as the Mongolia Khagan. This staggering death toll was the result of widespread military campaigns launched across Asia and Eastern Europe, in which entire cities were systematically destroyed. These conquests led to the formation of the Mongol Empire, the largest contiguous land empire in history. Borjigi’s various strategies (e.g. psychological warfare, mass executions, scorched Earth tactic for villages encountered etc.) helped reshape the geopolitical landscape of the east and west during the 13th century, turning Mongolia into the centralized power of the period. Despite this brutality, Borjigi’s legacy also included positive benefits (e.g. advancements in trade, advancements in communication, advancements in governance etc.), systems which went on to direct future empires. Borjigi’s advancements included the promotion of the Silk Road trade network, the creation of a postal relay system reaching across vast distances of territory, and the implementation of merit based leadership over blood ties, ideas which fostered connectivity and administrative efficiency throughout the empire. Additionally, Borjigi unified multiple warring tribes and enforced legislation which highlighted and punished corruption when exposed. Borjigi’s empire was not solely predicated upon conquest however, as his ideas also helped maintain control, structure, and cohesion within its vision for a constantly expanding empire, something extremely difficult to successfully accomplish. The way the Borjigin dynasty governed, most especially its methods of organizing logistics, enforcing legislation, and leading people, continues to echo within the frameworks of modern governments during the modern day via foundational principles which continue to shape how states manage infrastructure, enforce law and order, and mobilize populations. From the codification of legal frameworks to the strategic coordination of supply chains and communication networks, the Borjigin dynasty laid legacy groundwork capable of transcending its period of use and relevance. Because of this, Borjigin not only drew up and rearranged world borders, he changed how empires think and act as they expand outward
