The Basques have the greatest level of autonomy of any group in Spain. The goal of ETA is to create an independent Basque homeland, which is what their moniker means "Euskadi ta askatasuna": Basque Homeland and Liberty. I agree that Franco was an SOB to the Basques...they don't forget it, nor will they. Euskaraz (teaching Basque) was outlawed during the dictatorship, and even having a Basque flag (ikurriña) was illegal. My wife's uncle would've been thrown in jail, at age 14, had the Guardia Civil officer who caught him with an ikurriña not been a family friend...instead he told him to put it away, and he'd let him go...
You are also right that the Basques, although politically associated with Spain, never really came under Spanish "control" until recently (last century).
Sure the Basque region was part of Spain geographically, but don't be fooled,

, the only reason you didn't have an ETA-like group under former castellano kings was the the laissez-faire attitude that they held towards the Basques. They were allowed to be Basque, and then, when their military might was needed, they saw the Spanish monarch as an ally, who they deemed worthy of support. Today, that trust is broken.
Franco plundered the Basque land and shipped in a bunch of unemployed Spaniards from other portions of the country to work in the steel mills. By doing so, he tried to blur the lines between Basques and Spaniards, hoping to dilute the culture there until it became a non-issue. He failed, as the Basque language and culture are thriving. However, now there is a vocal minority of Basques who say "no more betrayal, we want out."
