The Age of Exploration: The Azores
The Portuguese continue to explore in every direction. The Atlantic islands of the Azores are about half the way to North America, but no one realizes it. The Azores are uninhabited so the Portuguese colonize it. Like the Madeira Islands, it will remain part of Portugal into the modern day.  
The Hussites Spank the Crusaders
Pope Martin the 5th is the right man at the right time. He is sternly rebuilding Rome, a city of 25,000 starving people, abandoned buildings and wolves wandering the streets. He is also making sense of the Church finances and maintaining control over the College of Cardinals. After 40 years of separation he is reuniting the Church, but the Hussites of Bohemia will not comply. General John Ziska has died of the Plague so the Pope thinks that the Hussites are now easy pickings. But what he doesn't realize is that before John Ziska died, he named a successor: not a second-stringer and not the equal of John Ziska. This man is EVEN BETTER! Prokop the Great will offer quarter to the 70,000 invaders but the Crusaders, who think they will need no quarter will offer none in return. So be it. The Battle of Assig is an absolute rout. The Crusaders will receive more casualties in retreat than in the battle itself.

The Crusaders fled without a fight and suffered considerable casualties from the villagers they had pillaged enroute to Meiss."

Than the Hussite heretics, the Turk himself, he said, was less the foe of Christianity; and it was a more urgent as well as a more meritorious work to endeavor to bring about the extirpation of the Bohemian adversary than the overthrow of the Moslem one."
