So how come your Country ended up being ruled by Spain and France? What happened there?
Long story short, in medieval times there were a bunch of small and medium sized kingdoms in what now is the Iberian peninsula, one of which was the Kingdom of Navarre, which included most (but not all) of the Basque-speaking areas.
Navarre was progressively conquered by the neighbouring, bigger Kingdom of Castile, roughly from the 12th to the early 16th century, after which Castile merged with the Kingdom of Aragon to form Spain. The part of Navarre that wasn't conquered by Castile survived as a kingdom only in name, but was merged with the French crown (so that the King of France was formally known as the King of France and Navarre) until the 19th century.
In the end, the four Basque territories under Spanish rule (Upper Navarre proper and three smaller ones that were conquered from her earlier in the process) ended up being four provinces of Spain, of which Navarre forms an autonomous region by itself and the other three together form another one; and the three Basque territories that ended up under French sovereignity (Lower Navarre and two other small provinces) were French provinces until the French Revolution dissolved the old territorial distribution, so legally speaking
they don't even exist anymore, and are part of one bigger French department.
[This is the "short" answer, so skip the next paragraphs if you're satisfied already.]
So ours is a nation divided in seven territories, four under Spanish sovereignity as two autonomous regions, and three under French sovereignity with no official recognition, other than a very recent so called "municipal community" which includes the three of them and is just a very weak form of administrative recognition.
To further complicate things, the name "Basque Country" has been progressively been applied only to the three westernmost provinces (which are officially named "the Basque Country") and the
Basqueness of Navarre is systematically denied by Spanish nationalists. Just imagine British people saying that Northern Ireland was never called Northern Ireland and is not Ireland indeed, you can only call it
Ulster.
If you want, try and search for "Basque Country" in Wikipedia. It will send you to a disambiguation page. Not long ago, it sent you to the page for the Basque Country proper and it told you
if you were searching for the Spanish autonomous region, go to Basque Country (autonomous region)". But now even the very definition of Basqueness is challenged.
So, not only are we not an independent country, we don't even have the right to have our name used properly anymore
