Contact between China and the Near East predates the advent of Islam in the seventh century; sea and land routes connected the two regions as early as the third century B.C. The main route was the Silk Road, named after the most important commodity that was traded along it—Chinese silk (see map). The ease of travel across Asia and the Middle East was facilitated in the thirteenth and fourteenth centuries by the Pax Mongolica (literally, "Mongol peace")—the unification under the Mongol conquerors, who swept through Asia establishing control over territories stretching from East Asia to eastern Europe (see map).
In addition to traveling by land routes, merchants also traded via sea routes, carrying luxury commodities such as ceramics, carpets, rice wine, musk, perfumes, paper, dyestuffs, pearls, ink, and ivory in great quantities.
During the reign of the Abbasids (750–1258) there was remarkable expansion in international trade. Sea routes stretched all the way from Iraq to Indonesia, and ships traveling back and forth would stop at many ports along the way to buy and sell goods. Abbasid merchants returned home with finished goods (such as ceramics, paper, silk, and ink from China) as well as raw materials (like spices from India and teakwood from Southeast Asia). This boom in trade transformed Iraq into an international marketplace in which prized Chinese and Southeast Asian imports such as silk, paper, tea, and ceramics were sold.
