Thanks to nostr:npub1anarchyz6kyuse7qgszk7awkelmefuvgd40teh2g4kz3mfr6mtjqkxpvms for reminding me of that time Spain and Portugal said "let's go halfsies on the entire planet"
Fun fact: you won't see anybody signing that treaty as "king (or queen) of Spain" -- because "Spain" didn't exist as a polity back then, and wouldn't for a couple more centuries.
And as a geographic concept, Portugal was as much "Spain" as Castille, Leon, Aragon, Granada...
So, no, actually "Spain" and Portugal did not really agree to anything.
Ah interesting, good catch! Although even though it was signed by royals of Aragon, Castile, and Asturias, it states that it "divided the newly discovered lands outside Europe between the Portuguese Empire and the Spanish Empire (Crown of Castile)". So how does that work?
Who does? Wikipedia -- not the Treaty or anyone who was there when it was signed.
It's an anachronistic expression, and it's specially ridiculous to invoke it at that specific time. Neither Ferdinand nor Isabel ever claimed the title of Emperor/ess.
You can forgive it in a non-academic and often extremely biased and manipulated source like Wiki, but not in a more serious text or if you want to be accurate.
