User blog:Jazon Naparleon/Questions of Romans and Mongols

I was wondering about a few somewhat-related things, attempts at research in other venues being fruitless, that I figured some of my wiki-mates here could help me resolve.


 * I: What if the Battle of the Khalakhaljid Sands  had gone a bit differently and Ogedai was killed, rather than wounded and lost?


 * II: Could the Mongols have actually conquered Japan had the weather not been atrocious, or would its mountainous terrain plus the Japanese Homefield Advantage been too much for Kublia Khan and his horde?


 * III: If Caesarion had escaped Octavian's grasp back to India, or simply stayed in India altogether, would he (Or one of his descendents) have been able to win control of Rome?


 * IV:What if Jesus (As in, Christ) was killed when he was a baby, in particular, how would it affect the longevity of the Roman Empire?
