Once again this is for the audiobook version.
I have read about Genghis Khan before, but this book delves so deeply into the topic that I was surprised constantly by it. The story of his family, the betrayals, in-fighting and both luck and skill on the battle field.
Funny enough, the one fact that sticks with me the most is that the Mongols were not a literate people, but to retain the knowledge of all the laws, and to relay orders across hundreds and thousands of miles without losing detail they would sing it in verse.
Evidently Mongols sung constantly when riding, and not just songs, but laws, instructions, etc. Singing is one of the ways to trick your mind not to forget specific wording, and avoid the horrid “telephone game” effect.
It is a very long listen, but it was worth all of it.
