Evidently when Spain and Portugal were splitting up the new world there was a lot of tension. A meeting was held and an agreement was come up with blessed by the Pope that half the world would go to Spain and the other half to Portugal.
But then Portugal lost to Spain in some war and the other half of the world went to Spain as well as the spoils of war.

Properly speaking you all should acknowledge Felipe VI as your rightful monarch. I have dedicated the rest of my life to work towards a unification of the world under the Bourbon dynasty. Granted, its a bit of a stretch goal really.
