The story of the Reconquista is pretty well known by those who trouble to study medieval history for themselves. It's not known in our public schools, because it's politically incorrect.
If you want a good summary of the events, you might look at the opening chapter of Warren H. Carroll, "Isabel of Spain: The Catholic Queen," Christendom Press, 1991. Some of the major events in the Reconquista are familiar in Spanish literature, notably the tales of Pelayo, Alfonso el Sabio, and El Cid Campeador.
