The Knights Templar were a religious organisation, but also a quasi-banking institution in Europe; they took and protected deposits of gold, and issued 'cheques' allowing, for example, travellers to deposit gold in London and spend the money in Southern Europe. They were dissolved because they were beginning to rival the Papacy and nations in power due to their immense wealth.
Also, few know this, but many African slaves who were victims of the slave trade became slaves due to debt-slavery (though this didn't involve formal banks). I've seen estimates of up to 25% of slaves back then having been debt-slaves.
Yes! I had heard a bit about the Knights Templar, I guess I would have categorized them as religious first, financial/governance functions second. But also the Order of Malta had quite a lot of power, to the point I believe that it is still recognized by the UN!
I hadn't realized that about African slaves; debt for what?
