Genghis Khan had a son, Juchi Khan. Juchi had a son called Batu. Batu had a son called Tutukan. Tutukan had a son called Monke. Monke had a son called Tochtu. Tochtu married Maria Palaiologos, and they had a son called Basarab I of Wallachia. Basarab had a son, Nicholas II. Nicholas had a son called Radu I. Radu had a son called Mircea I. And Mircea had a son called Vlad III Dracul.

Dracula was a direct descendant of Genghis Khan. I find this incredibly interesting. The powerful are attracted to the powerful, or at least will seek out the daughters of conquered nations to solidify their hold on power, and thus, they are assimilated into the conquered.
