The Templars started out living poor and a life of devotion to the scriptures. However, as the continuing crusades against the Muslims went on, they slowly accumulated wealth as papal bulls authorized them to keep whatever they acquired from the Muslims. The Templars also accepted gifts from the faithful as well as transporting valuable items from major trading routes and shipping lanes. Over the course of 200 years, the Knights gained dizzying amounts of wealth, land and at one point nearly 800 castles which later on served as full service banks. The Knights became bankers of Monarchs for their mortgages as well as offering loans to finance wars with their headquarters in Paris.
A knight could deposit money in Jerusalem
and make a withdrawal in the form of gold coins when he arrives in Paris. The
Knights templar has transformed into an institution of great wealth and power.
Nobody could seem to match their strength and they even planned to form their
own state just like how the Teutonic knights formed Prussia. However, all of
these would come to an end and all their wealth and influence would be brought
down over a loan and a series of Theocratic harassment by a struggling monarch,
King Philip IV of France.
