Religious persecution by “zealous Taoist” emperor Wuzong:
“The religious persecution reached its height in the year 845 CE, ultimately confiscating the Buddhist temple properties, destroying 4,600 Buddhist temples and 40,000 shrines, and removing 260,500 monks and nuns from the monasteries.[9] Emperor Wuzong's reasons for doing so were not purely economic. A zealous Taoist, Wuzong considered Buddhism a foreign religion that was harmful to Chinese society.”
