How would the world be different, or history would diverge, if
The Mongolian invasion of Japan was successful, with no typhoons ruining any of the Mongol ships, and Mongol overtaking the island.
Seems pretty possible, as the Japanese at the time did not know to handle against a large scale army. They did have a lot of skill in personal combat, but it would not be enough of a factor. The Mongol invasion would have most likely succeeded if the typhoons did not ruin much of their fleet.
The mongols+chinese had 140,000 troops, the Japanese had 40,000. 130,000 drowned or died before landing, drastically changing the war.
But what if the typhoons never occurred, and the Mongols still had their army of 140,000?
Would Japan eventually gain independence? Or Would Japan become part of Mongolia? How would world history play out differently, Sengoku Jidai, WW2, etc?
