Tem�jin Borjigin, his given name, Genghis Khan being a title, had four official sons, but he and they llived by the motto:
The greatest joy a man can know is to conquer his enemies and drive them before him. To ride their horses and take away their possessions. To see the faces of those who were dear to them bedewed with tears, and to clasp their wives and daughters in his arms"
Preferring rape and conquest to hunting and falconry, coupled with building an empire and "a social legacy that benefited his sons' sons unto the seventh generation and even beyond", meant that Genghis' progeny multiplied explosively, and his apparent Y-chromosome lineage today features prominently in the population genetics of Asia.

He died in A.D. 1227 as the result of falling off his horse, on whom he had literally lived his entire life.
His body has never been discovered so it remains speculation that the common DNA descendants are his, but no other historical figure could have been so proliferate...
