It was during the Crusade when there was an interaction between the Islamic World and Medieval Europe.

Explanation:

The crusade was not only a religious war, but it helped in exchanging cultures between Christians and Muslims. Crusades in the Middle East introduced items and goods which were new to Europeans. Muslims introduced textiles, spices, silk, carpets also foods like fruits, sherbet, sugar, rice, coffee. The Crusades helped Europeans to become conscious in traveling and businesses. Merchants began trading with the Muslims and opened trading links in Jerusalem. The crusades contribute to the spread of Renaissance ideas throughout Europe by opening contact with the Islamic World who knew cosmology, science, medicine, and mathematics.
