Aragon, Castile, and Aquataine, I believe and the remnants of the old Frankish kingdom of Germans.
And the famous "three cultures" (Christian, Jewish and Muslim) that people gush about was the city of Toledo, in Christian territory, ruled over by a Spanish Christian King (Alfonso X).
Most notably it was not Toledo but Seville, and the relationship were increadibly harmonious between for over 700 years.
Incidentally, that has not been the case at all ever since Isabella the Catholic who quickly made Spain sterile: she expelled not only Moors but her own non-Christian subjects subjects as well -- Jews and Roma. I find it interesting that, after the greatest of catastrophies, the Holocaust, there are bout 7,000 Jews in Munich 50 years later. In ontrast, there are no Jews in Spain, even 500 years after expulsion.
It was also very telling, when the official guide of Alhambra first of all pointed to the church on the hill. There you are, standing in the most magnificent creation of the Moors, suspended in time and space, but the lecture had to begin with the church that Isabella erected after tearing down the mosque.
The Sunday school history may not always be the authentic one. (FOr another good comparison consult Fiske on the Albigences affair, and then consult the official Catholic Encyclopaedia: what a difference).
