Triunfa, España!

Spain and Portugal were temporarily united under the Iberian Union between 1580 and 1640. The Union was one of the most powerful nations of the world until the misjudgement of their leaders made Portugal to re-gain it's independence. But what if the two crowns had fully fused? The richness of the Union post-unification would made a conquest of Italy possible. With Italian gold, maybe Philip II of Spain would have bribed the English Parliament so that the Ibero-Italian and the English crowns fused. This is what this timeline, Triunfa, España! ("Triumph, Spain!" in English), is about.
