The history of the missions of the Jesuits in China is part of the history of relations between China and the Western world. The missionary efforts and other work of the Society of Jesus, or Jesuits, between the 16th and 17th century played a significant role in continuing the transmission of knowledge, science, and culture between China and the West, and influenced Christian culture in Chinese society today.
The first attempt by the Jesuits to reach China was made in 1552 by St. Francis Xavier, Navarrese priest and missionary and founding member of the Society of Jesus. Xavier never reached the mainland, dying after only a year on the Chinese island of Shangchuan. Three decades later, in 1582, Jesuits once again initiated mission work in China, led by several figures including the Italian Matteo Ricci, introducing Western science, mathematics, astronomy, and visual arts to the Chinese imperial court, and carrying on significant inter-cultural and philosophical dialogue with Chinese scholars, particularly with representatives of Confucianism. At the time of their peak influence, members of the Jesuit delegation were considered some of the emperor's most valued and trusted advisors, holding prestigious posts in the imperial government. Many Chinese, including former Confucian scholars, adopted Christianity and became priests and members of the Society of Jesus.
According to research by David E. Mungello, from 1552 (i.e., the death of St. Francis Xavier) to 1800, a total of 920 Jesuits participated in the China mission, of whom 314 were Portuguese, and 130 were French. In 1844 China may have had 240,000 Roman Catholics, but this number grew rapidly, and in 1901 the figure reached 720,490. Many Jesuit priests, both Western-born and Chinese, are buried in the cemetery located in what is now the School of the Beijing Municipal Committee.
Contacts between Asia and the West already dated back hundreds of years, especially between the Papacy and the Mongol Empire in the 13th century. Numerous traders – most famously Marco Polo – had traveled between eastern and western Eurasia. Christianity was not new to the Mongols, as many had practiced Christianity of the Church of the East since the 7th century (see Christianity among the Mongols). However, the overthrow of the Mongol Yuan Dynasty by the Ming in 1368 resulted in a strong assimilatory pressure on China's Muslim, Jewish, and Christian communities, and outside influences were forced out of China. By the 16th century, there is no reliable information about any practicing Christians remaining in China.
