Just finished Genghis Khan -and the Making of the Modern World by Jack Weatherford. Great read. Was not the blood crazed barbarian that I though. He was extremely strategic and way ahead of his time when is came to a lot of areas such as trade, legal system, currency, and social issues. Teasers: In 25 years Genghis and his sons build an empire that was geographically larger than the Roman Empire at its peak. The Roman empire lasted 400 years. DNA experts claim there are between 12 million and 16 million people today that can be traced back to one common ancestor from that part of the world. Genghis Kahn is the most likely candidate.
