The Knights Templar had risen to be one of the most feared and powerful societies in the 1100s. Their fame and fortune were unlike any other “religious” society of the time, which drew much unwanted attention and scrutiny their way. Eventually, they were ostracized and disbanded because of their unrighteousness, lack of charitable contribution, and ruthlessness when it came to debt owed. I conclude that their eventual disbandment was not because of their unrighteousness on the whole, but mostly because the Pope and other powerful men owed them too much money. They were disbanded only 200 years after their creation, but their lore and mystery remains even today.
