If Columbus doesn't sail for Spain, what happens to the Spanish? Obviously butterflies are massive, as at this point the Catholic Monarchs still have three living children ahead of Joanna la Loca in succession, all of whom had deaths that are presumably easily butterflied, or at least delayed until after a potential heir has been sired, but I think that it's more important to focus on what Spain itself does.
Without an instant claim on half the Western World, what does Spain do? Do they focus all of their energy on Italy, or is there more emphasis on Africa or even on controlling Portugal? Without American gold and silver, is the Spanish economy more stable? Is the Spanish navy less developed early on without so many overseas posessions?
Just to tie up loose ends, we'll say that Brazil is still discovered in 1500 by the Portuguese, thus allerting the European powers to the possibility of new land in the west.
