Genghis Khan rose to power as a Khan after his father was poisoned and betrayed by its own. Mongols lived in felt tents called yurts. They raised canals, goats, horses, oxen and sheep. The Mongols created Yams. Yams are part hotel, part post office, and part military barracks. They also created the first passport. The passport was made out of a different material engraved with a symbol to show how important the person was. After Genghisś death, his sons and grandsons took over where he had last left off. The Mongols were savage conquerors of history.
