@steemitcountry, there has been violence between different schools of Buddhism and also rulers, mostly from the Brahman caste. I've read stories of one Brahman King sought vengeance on Buddhist monasteries because the Brahmins lost power and wealth when Buddhism became the favored religion of rulers. He destroyed monasteries in his kingdom and killed many monks. The Brahman leaders could no longer make money from sacrificing animals to the Gods and lost influence with the elites. Eventually, Buddhism died out in India because the monasteries lost touch with the everyday people who supported their needs, they no longer taught how to overcome suffering and avoided ordinary people for purity's sake, plus competing religions including Islam became popular.
