 The main factor which boosted industry and trade under the Ayyubids was the new interests Europeans developed when they came into contact with the Muslims . Commodities included incense , scents , fragrant oils , and aromatic plants from Arabia and India , as well as ginger , alum , and aloes . Likewise , Europeans developed new tastes in the matter of fashions , clothing , and home furnishing . Rugs , carpets , and tapestries manufactured in the Middle East and Central Asia were introduced to the West through Crusader @-@ Ayyubid interaction . Christian pilgrims visiting Jerusalem returned with Arab reliquaries for the keeping of relics . In addition , eastern works of art in glass , pottery , gold , silver , etc . , were highly prized in Europe .
