Now most folks often associate the Knights Templar with being knights. You can see here one of the knights on horseback. Here you see the knights protecting pilgrims on their way to Jerusalem, and they did do that. 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.
