“The Crusader states were able to cling to survival only through frequent delivery of supplies and manpower from Europe. [They] were defended primarily by three semi-monastic military orders: the Templars, the Hospitallers, and the Teutonic Knights. Combining monasticism and militarism, these orders served to protect pilgrims and to wage perpetual war against the Muslims.”

Palmira Brummett, world historian, 2007

“Whenever I visited Jerusalem, I always entered the al-Aqsa Mosque, beside which stood a small mosque which the Franks had converted into a church ... [T]he Templars, ... who were my friends, would evacuate the little adjoining mosque so that I could pray in it.”

Usamah ibn Munqidh, Muslim historian,

Jerusalem, circa 1138
