大秦景教流行中国碑
Opposition arose to the Christians in 698-699 from the Buddhists, and then from the Daoists in 713, but Christianity continued to thrive, and in 781, a stone stele (the Nestorian Stele) was erected at the Tang capital of Chang-an, which recorded 150 years of Emperor-supported Christian history in China. The text of the stele describes flourishing communities of Christians throughout China, but beyond this and few other fragmentary records, relatively little is known of their history. In later years, other emperors were not as religiously tolerant. In 845, the Chinese authorities implemented an interdiction of foreign cults, and Christianity diminished in China until the time of the Mongol Empire in the 13th century.
