"The Moslem rulers of India often maintained youthful male lovers, and male brothels flourished. Burton visited a number of them in 1845. At first glance, the early Mongols appear to have been an exception to the broad pattern. The Great Yassa, a law code issued by Ghenghiz Khan or at his death for the still-pagan Mongol tribes around 1219, to supplement Mongolian customary law, mandated the death penalty for both sodomites and adulterers. This is not what one would expect in a tribe of nomadic pastoralists with a shamanistic religion. It seems likely that this severe penalty reflects the influence of Christians, Jews, or Moslems, to whom Ghengiz extended hospitality. Ghenghiz was himself illiterate, and might well have called on a literate foreigner to prepare a code of laws."
