Hold on,
800,000 inhabitants were not rich at all. And yet, they were brutally massacred.
"800,000 of the inhabitants were brought out in batches from the city to be massacred, and the greater part of the city itself was destroyed by fire
800,000 in baghdad yes? It was a rich city, therefore it was massacred incase they betrayed the mongols. But it wasn't Genghis who did that, i believe it was his grandson who led the invasion into whats today Iraq.
