The Chinese Rites controversy was a dispute among Catholic missionaries over the religiosity of Confucianism and Chinese rituals during the 17th and 18th centuries. The debate discussed whether Chinese ritual practices of ancestor veneration and other formal rites qualified as religious, and thus incompatible with Catholic belief. The Jesuits argued that these Chinese rites were secular rituals that were compatible with Christianity, within certain limits, and should thus be tolerated. The Dominicans and Franciscans, however, disagreed and reported the issue to Rome.

The Kangxi Emperor, also known by his temple name Emperor Shengzu of Qing, personal name Xuanye, was the third emperor of the Qing dynasty, and the second Qing emperor to rule over China proper. His reign of 61 years makes him the longest-reigning emperor in Chinese history and one of the longest-reigning rulers in history. He is considered one of China's greatest emperors.
