They did protect the pilgrims, and they were also active in battle during the Crusades thereafter. But it turns out that even though at the peak there were on the order of 20,000 Knights Templar, only about 10% of them were actual soldiers, were actually these warrior monks, as they're sometimes called, the rest of the Templars created this fairly significant, complex infrastructure to do multiple things to support the goal of the Knights Templar, and perhaps most significantly, they developed a sprawling financial enterprise of the time. If you were in London, and you wanted to do a pilgrimage to the Holy Land, you would need resources in order to do that, and you would want to have access to your wealth once you got to Jerusalem, and so you could imagine if you're traveling over a long journey to take gold coins with you, not only would they be heavy, but more importantly, they would be dangerous. A lot of people might want to take that gold from you. And so one of the services that the Knights Templar developed was that you could go to their temple in London, essentially deposit your money, they'll give you a note of credit saying that we, the Knights, owe you a certain amount of money, and then you make your journey, and when you get to Jerusalem, you can give that note to the Knights there, and they will give you your money. Now this is something that we take for granted today. I can go to an ATM machine anywhere in the world, and for the most part, I can put in my ATM card and get access to money.
