Mongol Empire

We get a taste of Khal Drogo's brutal, nomadic lifestyle when young Daenerys Targarian is married off to him. Strength is prized generally in Dothraki culture, and being some of the world's deadliest warriors, they spread fear throughout the nation.

The Mongol empire, which dominated much of Asia and Europe in the 13th and 14th centuries, was similar to this in many ways. The Mongols, like the Dothraki, were fierce warriors who vanquished foes while mounted and were always on the go. The Dothraki imitated the Mongol practice of teaching children to ride and battle from a young age, learning archery and riding from a young age.

Genghis Khan, a legendary warrior and fornicator who is still held accountable for around 0.5 percent of the world's male population built the Mongol Empire. He served as the model for Khal Drogo, who was regarded as the most fearsome Khal of them all.
