I know it’s a shitpost, but here’s an interesting piece of History:

• Back in the late 15th century, before Christopher Colombus officially discovered the Americas (more on that later), the Portuguese and the Spanish made a Treaty - the Treaty of Tordesillas - where they divided the World in half, each one getting one half of it.
• Whilst making the Treaty, the original proposal was that the dividing line (remember, this was before the first trip around the World) would be a North-South line, located 20 nautical miles East of the Cape Verde Islands (which are just East of the coast of Africa). With the Portuguese side being to the East of that line and the Spanish side to the West.
• The Portuguese refused that location and instead wanted that line 20,000 nautical miles East of the Cape Verder islands, which was what ended up in that Treaty.
• Where is now Brazil is to the East of that line, on the Portuguese side, and the rest of South America is to the West of that line, on the Spanish side

This is why the Portuguese and the Brazilians speak the same language, whilst the rest of South America speaks the same language as the Spanish.

Nowadays it’s actually believed the Portuguese discovered the Americas before Christopher Columbus did (hence explaining the insistence on the location of that line in the Treaty), though there’s also proof that the Vikings discovered the Americas centuries before that.
