Madog and Englishmen
The Last Prince of Wales was the first nobleman to be drawn and quartered for his part in the previous Welsh rebellion but Wales is not yet pacified. King Edward I of England is building castles throughout Wales to press his advantage and he has imposed a 15% tax on "all movables" which one presumes to mean "anything that isn't nailed down." The people of Wales have rebelled again and Madog ap Llywelyn, sets himself at their front even though King Edward has been favoring him (probably because Madog opposed the Last Prince of Wales). This rebellion will go well for Madog until summertime of next year when the rebellion will collapse with terrible losses and Madog will be captured but he will not suffer capital punishment. King Edward will impose even harsher sanctions on the Welsh people. The pot is boiling and the King has clamped down on the lid. 
No One Crushes This Alliance
What do the Napoleonic Wars, World War I & II and the Falklands War all have in common? The alliance between Portugal and England is more of an understanding than a mutual defense treaty at this time but it will settle the succession crisis in Portugal when King Ferdinand I dies. This alliance will be formalized in the Anglo-Portuguese Treaty of 1373 and will draw England into war a number of times including World War I and II. Churchill will stun Parliament by citing the Anglo-Portuguese Treaty of 1373 as the reason he is allowed to establish an air and naval base in the Azores. This same facility will be used during the Falklands War as well. And the alliance will draw England into the war against Napoleon when the Duke of Wellington will say:
"All the business of war, and indeed all the business of life, is to endeavor to find out what you don't know by what you do; that's what I called 'guessing what was at the other side of the hill.'" 
No One Kow-Tows to Khan Any More
"In Xanadu did Kubla Khan / A stately pleasure-dome decree: / Where Alph, the sacred river, ran / Through caverns measureless to man / Down to a sunless sea."
Kublai Khan had not been paying much attention to his Empire in recent years as his string of failures will attest. Since the death of his wife and son, he has been spending more time indulging in alcohol and nursing his ailments than running the Empire. Now his time has run out to that "sunless sea" and he is no more. He was 79 years old and suffering from gout, alcoholism and obesity. Kublai Khan will be succeeded by his grandson, Temur Khan, but he won't be able to hold the Empire together. This greatest Empire will break up into four parts.
