<P> At its height, the Mongolian empire stretched from Shanhaiguan in the east to Budapest in the west, from Rus' in the north to Tibet in the south . This meant that an extremely large part of the continent was united under one political authority . As a result, the trade routes used by merchants became safe for travel, resulting in an overall growth and expansion of trade from China in the east to Britain in the west . Thus, the Pax Mongolica greatly influenced many civilizations in Eurasia during the 13th and 14th centuries . </P> <P> Before the Mongols' rise, the Old World system consisted of isolated imperial systems . The new Mongol empire amalgamated the once isolated civilizations into a new continental system, and re-established the Silk Road as a dominant method of transportation . The unification of Eurasia under the Mongols greatly diminished the number of competing tribute gatherers throughout the trade network and assured greater safety and security in travel . During the Pax Mongolica, European merchants like Marco Polo made their way from Europe to China on the well - maintained and well travelled roads that linked Anatolia to China . </P> <P> On the Silk Road caravans with Chinese silk; pepper, ginger, cinnamon, and nutmeg came to the West from the Spice Islands via the transcontinental trade routes . Eastern diets were introduced to Europeans as well . Indian muslins, cottons, pearls, and precious stones were sold in Europe, as well as weapons, carpets, and leather goods from Iran . Gunpowder was also introduced to Europe from China . In the opposite direction, Europeans sent silver, fine cloth, horses, linen, and other goods to the near and far East . Increasing trade and commerce meant that the respective nations and societies increased their exposure to new goods and markets, thus increasing the GDP of each nation or society that was involved in the trade system . Μany of the cities participating in the 13th century world trade system grew rapidly in size . </P> <P> Along with land trade routes, a Maritime Silk Road contributed to the flow of goods and establishment of a Pax Mongolica . This Maritime Silk Road started with short coastal routes in Southern China . As technology and navigation progressed these routes developed into a high - seas route into the Indian Ocean . Eventually these routes further developed encompassing the Arabian Sea, Persian Gulf, Red Sea, and the sea off East Africa . </P>
