Mr Levavi
According both to historians and legend the Muslim invasion in 732 was made possible because of betrayal in the Wisigothic Army. Betrayal by Christians. But the capture of Toledo, the Wisigothic capital, was due to betrayal by Jews.
Fast forward a few centuries. Christians have suffered a cruishing defeat at Alarcos at the hands of the Almohades (a North-African group of tribes who have invaded Spain) and know the later are preparing another expedition Northwards. Due to the losses at Alarcos the Christians have been forced to complement their forces with poor quality city milicias. But they are still outnumbered nearly two to one so they called for a crusade and thanks to the crusaders they have reached near parity with the Muslim Army. In addition the crusaders are far better quality than the city militias. Problem is that their favourite distraction is killing Jews. And the Catalian king ended sending them back before this battle he couldn’t afford to lose. Aftermath: the Christians won decisively and slaughtered the Muslim Army. However it was a very close thing and the outcome could have been the exact opposite.
Fast track again. A young man called Ferdinand who has at least one jewish grand father becomes king of Aragon and marries the queeen of Castilla named Isabel whose confessor Torquemada is also an inquisitor and has Jewish ancestors…
