Islam during the Yuan dynasty

During the Yuan dynasty in the 13th century, there was a significant increase in the population of Muslims in China. Under the Mongol Empire, east–west communication and cross-cultural transmission were largely promoted. As a result, foreigners in China were given an elevated status in the hierarchy of the new regime. The impact on China by its Muslims at this time, including the advancement of Chinese science and the designing of Dadu, is vast and largely unknown. It is estimated that the population of the Hui minority grew from 50,000 in the 9th century to 4,000,000 in the 14th century, becoming the largest non-Han ethnic group.
