B. The Yassa Gengizcani (Mongol Code of Conduct) also known as Genghis Kahn’s Code of Laws or the Mongolian Code of Laws. The quote above is specifically #13 in the Code.
Genghis Khan drew from his Mongol military organization and also created a code of laws, the Yassa, which was a combination of his will and tribal customs.
The Yassa aimed at 3 things:
1. obedience to Genghis Khan;
2. a binding together of the nomad clans; and
3. the merciless punishment of wrong-doing.
The Yassa concerned itself with people, not property. Unless a man actually confessed, he was not judged guilty unless he was caught in the act of crime. Among the Mongols – who did not read – a man's spoken word was a solemn matter. The Yassa was very different from most other Code’s from the past.
