In short
In 1206, a Mongol warrior named Temüjin united the fractious tribes of the steppes and took the title Genghis Khan—a proclamation that would reshape the political map of Asia and beyond. Over the next few decades, his armies conquered territory from the Pacific to the Black Sea, creating the largest contiguous land empire in history. The event marked the beginning of a transformation that redrew borders, redirected trade routes, and altered the genetic and cultural makeup of entire continents.
