When the crusades were happing
The jewish didn't know much about Jerusalem but it was the holy temple. They were in it because it was the holy land.There was the destiny for them to go there.
The point of view was to defend the city of jerusalem. From that the strong one were killed or burned alive. The rural jews were expelled or obliterated. The rest were sold into slavery.
The effect of the jews was big. They weren't allowed to go into the holy temple they had to pay the king for a small room for all of them were going.But they were released from slavery.
They said that they were equals to the others.But i beg to differ. I think that they were lower to the Christian. Either that or they were higher because they were apart of the "christ killers".
