(20 POINTS, PLEASE ANSWER SOON!!) What effect did the Crusades have on the spread of Muslim advances in science and medicine in the Middle Ages?

One effect of the Crusades was the creation of a new hero for the Islamic world: Saladin, the Kurdish sultan of Syria and Egypt, who in 1187 freed Jerusalem from the Christians but refused to massacre them as the Christians had done to the city's Muslim and Jewish citizens 90 years previously.

the ss was the main organization responsible for the genocidal murder of around six million people of european ethnic minorities, essentially jews, in the holocaust. the members of all its branches committed war crimes and crimes against humanity during the second world war (1939-1945). likewise, the ss were involved in commercial enterprises and exploited the inmates of the concentration camps as slave laborers.

the tortures and assassinations committed by the ss were the result of an ideology developed long before the armed conflict, this ideology was based on the racial supremacy of the germans over the rest.
