Genghis Khan mastered the art of 'daughter diplomacy' to become the ultimate force of the East. He married his daughters off to allied kings, but with a twist—he required the kings to dismiss their other wives and serve in his military campaigns. His daughters took over their husbands' kingdoms, which were strategically expanded through war. By ensuring his son-in-laws were at the front lines and often perished, Genghis Khan's daughters inherited these lands, thus reinforcing the Mongol Empire’s defenses and securing its growth.
