Catholic Church in Sichuan
The presence of the Catholic Church in the southwestern Chinese province of Sichuan and city of Chongqing dates back to 1640, when two missionaries, Lodovico Buglio and Gabriel de Magalhães, through Jesuit missions in China, entered the province and spent much of the 1640s evangelizing in Chengdu and its surrounding areas. The Paris Foreign Missions Society assumed full responsibility for the Sichuan Mission in the 18th century.
