Rise of the south: How Arab-led maritime trade transformed China, 671–1371 CE

China's center of socioeconomic activities was in the North prior to the Tang dynasty but is in the South today. We demonstrate that Arab and Persian Muslim traders triggered that transition when they came to China in the late seventh century, by lifting maritime trade along the South Coast and re-creating the South. Between 742 and 1393 CE, prefectures with better access to maritime trade, or higher porcelain trade participation, experienced significantly higher population growth, but the predictive coefficient weakened substantially after the maritime trade ban of 1371 CE. These findings are robust after controlling for many confounding factors.
