Just a thought...
Let's say that King Edward IV of England manages to live a bit longer, dying around the age of fifty in 1492--not too much of a stretch. What would the last eight years of his reign be like, in relation to domestic and foreign policy in England? I've heard it said that his policies were very similar to those adopted by King Henry VII, especially in terms of administration and trade. Is this accurate?
Also, assuming the POD is 1483, you have at this time King Edward's eldest son, OTL Edward V, betrothed to Anne of Brittany. His sisters, Katherine and Anne of York were also betrothed to Juan of Aragon and Philip the Handsome respectively. So, what would English foreign policy look like over the next decade ITTL? Particularly relations between France, England and the Empire after the Treaty of Arras?
Just curious. I've considered writing a Yorkist TL at some point in the future, but I've had trouble conceptualizing exactly what the period of 1483-1493 would look like in this scenario.
