"A peasant rebellion against excessive imperial grain taxes in Central China." [Fall and Rise of China Guidebook, p. 200]
"The White Lotus Rebellion (...) was a rebellion initiated by followers of the White Lotus movement during the Qing dynasty of China. The rebellion began in 1794, when large groups of rebels claiming White Lotus affiliations rose up within the mountainous region that separated Sichuan province from Hubei and Shaanxi provinces. A smaller precursor to the main rebellion broke out in 1774, under the leadership of the martial-arts and herbal-healing expert Wang Lun in Shandong province of northern China. Although the rebellion was finally crushed by the Qing government in 1804, it marked a turning point in the history of the Qing dynasty. Qing control weakened and prosperity diminished by the 19th century. The rebellion is estimated to have caused the deaths of some 100,000 rebels." [Wikipedia]
