Point of clarification. What are you looking for when you say "a general history of the Reconquista?" Although the underlying crusade ideology is there for the Christians, and as time wore on Muslims definitely realized their al-Andalus (by then comprised of many little kingdoms) was losing ground to a bunch of Christians, overall it's hardly a unified campaign or even always primarily making progress. There are larger swathes of time where territory either isn't changing hands, or already conquered territory is being filled in (most of the Iberian interior was fairly empty), or Christian and Muslim statelets alike are batting away at each other, making and breaking alliances. "Reconquista" is kind of a convenient name, but the point is, it's not really separate from the political and social history of later medieval Iberia.

Is that what you're looking for? Or are you looking for more, military history-style accounts of battles, sieges, civil wars?
