I've recently heard a lecture about the Islamic history of Spain; Grenada and Qortuba. And I understand (not really), that there's a celebration of the expulsion of Arabs. It's not the celebration that I'm asking about, but how did the expulsion come through? When did it happen? Under whose authority? Why?
Sorry if the question is vague, or sounded wrong, I'm new to the subreddit :)
The Spanish term for the expulsion of the Moors is called the Reconquista, it started roughly with the battle of Covadonga in 718 between the Umayyads and an army lead by a Visigoth named Pelagius resulting in the principality of Asturias and ends with the fall of Grenada in 1492. As for celebrations, in Valencia there is a series of festivals called Moros y Cristianos.
