The Secret Burial
One of his post-death rules was that he should be buried privately, with no indication of where his grave is. His most loyal followers tended to proceedings right after his death, and his army ensured that nobody followed them. An important rule he had set was for horses to ride over his grave sight as much as possible, to remove any indication of its existence. Eight centuries later, nobody knows where the location actually is.
The Archery Rule
Khan’s success can be attributed to the strength of his armed forces, which helped him to create an empire that goes unparalleled by any other. His biggest rule around the army was that everyone had to know how to be skilled archers. He instructed Mongol children to learn from a very young, with the intention that they would become soldiers when they became of age. Horse riding, wrestling and other important skills were compulsory to learn too.
