Jarlig
A jarlig, also written yarlyk (from Russian: ярлы́к and Ukrainian: ярлик), is an edict, permission, license, or written commandant of Mongol and Chinggisid rulers' "formal diplomas." It was one of three non-fundamental law pronouncements that had the effect of regulation or ordinance, the other two being debter (a record of precedence cases for administration and judicial decisions) and billing (maxims or sayings attributed to Genghis Khan). The jarlig provides important information about the running of the Mongol Empire.
