The King Crusader is Dead
King Louis IX of France sets out on the Eighth Crusade to counter the threat of the Mamelukes (former Egyptian Muslim slaves) ...only to die at the gates of Tunis during a siege, probably from tainted water. His brother, Charles I of Sicily, and the Sultan of Tunis agree to end the siege. In the meantime, the Mamelukes are on the rampage in the city of Ashkelon. The city will be destroyed and the harbor filled in. It will never be rebuilt. The Crusader States are in trouble so Prince Edward I heads to Syria to make a stand.  
The Koreans are Revolting!
The Koreans are rebelling against the puppet government set up by their Mongol overlords. This is yet another example of the tenuous hold Kublai Kahn has over his Empire. The only people the Koreans will hate more than the Mongols will be the Japanese, but that is far in the future. For now, the Mongols are enough.  
To Sum Up.... God Is Logical!
Thomas Aquinas completes his Summa Theologica which contains, in part, a logical proof of the existence of God. It is an impressive piece of logic but over time, counter arguments will weaken his original line of logic. His work remains an important part of philosophical thought to this day.
