 Palestine had always been a crossroads for trade; now, this trade extended to Europe as well.European goods, such as the woolen textiles of northern Europe, made their way to the Middle East and Asia, while Asian goods were transported back to Europe.Jerusalem was especially involved in the silk, cotton and spice trade; other items that first appeared in Europe through trade with crusader Jerusalem included oranges and sugar, the latter of which chronicler William of Tyre called "very necessary for the use and health of mankind."
