The Christian Crusades
The Crusades had an important impact upon the
Christian world through intensifying the existing
European borrowing of the more sophisticated
technology, architecture, medicine, mathematics,
science, and general culture of Muslim civilization.
Europeans recovered much Greek learning lost after
the fall of Rome.
Italian merchants remained in Islamic centers after the
Crusader defeat and were far more important carriers
of Islamic advanced knowledge than the Christian
warriors.
Muslim peoples were little interested in aspects of
European civilization.
