Museum of the Rockies

It's large and impressive.  Not humongous like the British Museum or the Louvre, but for a small city in Montana (Bozeman) it's outstanding.

The largest exhibit is Genghis Khan, vicious warlord, empire builder, statesman with democratic foresight and tolerance.

Triple crossbow with 10' arrow.  Not sure how this weapon was used, maybe line up 5 enemy soldiers and impale them?  Skewer and elephant?

Parts of the Great Yasa, laws set down by the Khan.  Although some of the penalties are severe, and I can't endorse the clothing policy, the tolerance for religious beliefs, etc is awesome.  Our politicians and religious zealots would do well to follow the Khan's advice.

The Khan had 4 sons that didn't get along at all.  They split up the empire, let it fall apart.
