Here are some one liners...
Gutenberg Is Sued for Printing -- The Gutenberg printing press is not out yet, but apparently he's been experimenting and it didn't turn out well. Gutenberg is sued. (I also mention Korean efforts at movable type printing.)
China: The Great Wall Withdrawal --China is pulling back and building up it's defenses. The first part of The Great Wall has been completed. I also mention the French Maginot Line and ISIS.
Parliament: It's a Swedish Thing --It's their first parliament and in Old Norse the word "thing" means "assembly".
100 Years' War: Burgundy Packs It In --The Duke of Burgundy makes a deal with the King of France and switches sides! (He knows which side of the buttered bread hits the floor first.)
