Followers of the Eight Trigram Sect loyal to Lin Qing attack the Forbidden City in a failed attempt to oust the Jiaqing Emperor of the Qing dynasty.
Baguadao
Baguadao or Eight Trigram Teaching (八卦教) or Attain Origin Sect (收元教) or Pure Water Sect (清水教) is a network of Chinese folk religious sects, one of the most extended in northern China. The tradition dates back to the late 17th century Ming dynasty, and was heavily persecuted during the following Qing dynasty when affiliated sects organised an uprising in 1813, led by Lin Qing. Affiliated sects appeared under various names, but during the latter half of the 18th century they adopted Bagua Jiao as their common designation.
Forbidden City
The Forbidden City is the imperial palace complex in the center of the Imperial City in Beijing, China. It was the residence of 24 Ming and Qing dynasty Emperors, and the center of political power in China for over 500 years from 1420 to 1924. The palace is now administered by the Palace Museum as a UNESCO World Heritage Site. The Forbidden City is arguably the most famous palace in all of Chinese history, and is the largest preserved royal palace complex still standing in the world.
Eight Trigrams uprising of 1813
The Eight Trigrams uprising of 1813 broke out in China under the Qing dynasty. The rebellion was started by some elements of the millenarian Tianli Sect (天理教) or Heavenly Principle Sect, which was a branch of the White Lotus Sect. Led by Lin Qing and Li Wencheng, the revolt occurred in the Zhili, Shandong, and Henan provinces of China.
Jiaqing Emperor
The Jiaqing Emperor, also known by his temple name Emperor Renzong of Qing, personal name Yongyan, was the sixth emperor of the Qing dynasty and the fifth Qing emperor to rule over China proper. He was the 15th son of the Qianlong Emperor. During his reign, he prosecuted Heshen, the corrupt favorite of his father and attempted to restore order within the empire while curbing the smuggling of opium into China. Assessments of his reign are mixed, either seen as the "beginning of the end" of the Qing dynasty, or as a period of moderate reform that presaged the intellectual movements of the 1860s.
