Which continent is the first spanish speaking country on?

This question is a bit tricky! It depends on how you define "first".

* Historically: The first Spanish-speaking country was Spain itself, located in Europe.

* Geographically: If you're looking at the continents from west to east, the first Spanish-speaking country would be Chile in South America.

So, depending on what you mean by "first", the answer could be either Europe or South America.
