Combining the "Edward IV doesn't marry Elizabeth Woodville" and "George marries Mary of Burgundy" ideas, let's setup the following scenario: Warwick dies in 1464, with Edward IV marries Joanna of Portugal. George of Clarence marries Mary of Burgundy in 1466, with Charles the Bold having no male children. Prince Afonso still dies, with his cousin Manuel dying as well, with Joanna succeeding her brother. With members of the House of York ruling England, Portugal, and Burgundy, how does change the following decades?
