There were four divisions of brothers in the Templars:
- the knights, equipped as heavy cavalry
- the serjeants, equipped as light cavalry and drawn from a lower social class than the knights
- farmers, who administered the property of the Order
- the chaplains, who were ordained priests and saw to the spiritual needs of the Order.
On October 13, 1307, what may have been all the Knights Templar in France were simultaneously arrested by agents of Phillip the Fair (Phillipe le Bel), to be later tortured into "admitting" heresy in the Order.
During extreme torture (as documented in "Born in Blood" By John Robinson), some Templars "admitted" to worshipping a "bearded head." Some authors (such as John Robinson) discount this as a common accusation from the Inquisition, and therefore a typical forced admission, while others use it as the basis of conspiracy theories (such as Michael Baigent).
