Gutenberg Is Sued for Printing
The Gutenberg printing press is going to change everything but it's exact beginnings are murky. The first official mention of Johannes Gutenberg and any kind of printing is in a lawsuit he is currently involved in. Whatever he did, he was apparently experimenting with printing before now. He won't introduce a printing press with movable type until around 1439... just a few more years. When he does, he is going to put more than a few copyists out of work. They will manage to hang on for a time. The artwork they create in books is valued just for the beautiful lettering, but in the long run, copying books by hand will become a rare event.   
China: The Great Wall Withdrawal
With the death of the Yongol Emperor, China has begun a policy of withdrawal. In previous years they had pushed into what is present day Vietnam and north into Mongolia, but they have met heavy resistance. The "Great Viet" dynasty (Dai Viet), kicked the Chinese out in 1428 and the Mongols have been pushing back hard. This has led to a Chinese embargo of goods to Mongolia. China has also completed a series of defensive walls to the north of Beijing. Most people today call it "The Great Wall of China" but the Ming Dynasty calls it the Border Barriers. It is not the first such wall to be constructed but the Ming dynasty will discover that when men abandon the defensive walls, a wall is no defense at all.    
Parliament: It's a Swedish Thing
If you recall, in 1280, King Magnus the 3rd of Sweden offered to make anyone a noble (and given them tax-free status) if they would pay a lump sum or commit an able-bodied son to the king's army as a knight. This year Sweden has a meeting of the nobles in Arboga for their first parliament or "Riksdag of the Estates". It is an informal gathering of the nobles with their own interests in mind. No peasants are represented. The word "Riksdag" comes from the old Norse word "thing" which means "assembly".   
100 Years' War: Burgundy Packs It In
After Joan of Arc was burned at the stake, it was thought that a rather troublesome problem had been resolved, but Joan's inspiration, even after death, has quietly infused the French troops with the will to win. It is obvious now which way this war is going and the Duke of Burgundy is on the wrong side. Time to switch. Phillip the Good, Duke of Burgundy, signs a treaty with King Charles the 7th of France and joins the King in his war against the English. In exchange, King Charles promises to punish those who murdered Phillip's father, John the Fearless, who died unexpectedly... with an axe through his head.

He signed a peace treaty with Charles VI which recognized Charles as the one king of France. Charles promised in return to punish the murders of Philip's father.

A truce then ensued between Britain and France that lasted 13 years."
